PHOTOLUMINESCENT POWDER INTRODUCTION

    PHOTOLUMINESCENT POWDER INTRODUCTION

    Photoluminescent powder, also known as pigment, is a

non-toxic, non-radioactive new environmentally friendly alkaline earth aluminate pigment. Most of the visible or UV light

will charge the pigment particles (excitation). The photo luminescent pigment then releases energy for 10 to 24 hours in the

form of visible light (which glows in the dark). The photographic light-emitting pigments provide duty-cycle operation

with a very high ratio of glow time to the desired charging time. Luminous intensity (brightness) and afterglow time than the

traditional ZnS (zinc sulfide) or usually sold retail store products more than 30 times higher.

                Photoluminescent Powder Characteristics
 
                        Safe for normal uses as it contains no radioactive or toxic materials.

                   
                        Long glow time. Compared with previous photo storage materials, it has up to 50 times longer emission

(glow) time.

                   
                        High initial brilliance. Initial luminance of up to 40,000 mcd/m2.

                        High durability. Long shelf life if the crystalline structure is not damaged.

                   
                        Outdoor usage. Suitable for outdoor usage as it does not suffer luminance reduction even when placed

under a 300-watt high-pressure mercury lamp for 1000 hours.

                   
                        Stable Chemical Reaction. Not-encapsulated powder is stable as it is resistant to most anhydrous

chemicals, both organic and inorganic. However, it will decompose into metal oxide and lose its luminance when brought into

contact with water. Waterproof powder should be used for high water content mediums such as kids water paint. Most resin,

epoxy, silicone and acrylic paints can be used with our not-encapsulated pigment and brighter pigment.

                        Temperature Resistance:

                            High Temperatures. The performance and brilliance remain stable under temperature of nearly 1100

degrees Fahrenheit (600℃).

                            No decrease in performance even when tested at temperatures of -40 degrees Fahrenheit (-40℃).

High durability.

                How bright are these glow products?
           
           
                Many photoluminescent pigments and products manufacturers refer to

the extinction time of their products, which is defined as the time required for afterglow to be reduced to 1 masb (0.032 mcd

/ m2, or about 100 times the human perception limit). In practice, it is very difficult, unless your eyes are completely dark

to adapt, and you are in a completely dark environment.
For practical purposes, the brightness of one to two millimeters per square meter is a more appropriate limit for life safety

applications, even if a smoke-free environment is assumed. Therefore, the zinc sulfide product may take 30 to 45 minutes

after its excitation source is extinguished. On the other hand, the afterglow of strontium aluminate products can be seen for

days or even longer. All PhotoLuminescent Powder are based on strontium aluminate.
At the other end of the time scale, strontium aluminate products can provide surprising initial afterglow. For example, four

inches of square material from the magazine page can provide enough light, at least in the first minute. In addition, the

microprism retroreflector and other brightness enhancement techniques can increase the brightness of the material several

times.

    Are Photoluminescent Exit and Egress Signs OSHA Compliant?


    Most people can figure out how to exit a building in normal circumstances. But add fear and an emergency, and normal

tasks suddenly become difficult. Darkness after losing power and a fire’s smoke make everything worse. This is why it’s so

essential to make egress—the act of escaping a building—simple and easy. And glow in the dark exit signs that are approved

by OSHA are one way of lighting the way to safety.


    In this article, we look at the requirements from OSHA, NFPA, and the IBC for the listing and performance of

photoluminescent signs. These mandates include the need for

proper light sources, glow duration, and legibility from a distance.


    Feel free to skip to the sections on:

            The basics of photoluminescent exit signs and egress markers

       
            Listing requirements from IBC, NFPA 101, and others for photoluminescent signs

       
            Are photoluminescent signs OSHA-compliant?

            Installing, inspecting, and testing photoluminescent safety signs

    The basics of photoluminescent exit signs and egress markers


    Effective means of egress are described and regulated by multiple model building and safety codes. The National Fire

Protection Association’s NFPA 101: Life Safety Code (2018 edition) is one key document. Another is

the International Building Code (IBC, 2018 edition), which has been incorporated into the building codes of every

U.S. state.


    Proper signage is a key part of emergency preparedness, which is why you see light-up “EXIT”

signs everywhere. Smaller egress markers, which often have arrows indicating direction and pictographs of a

running man, are also common. These give directions in confusing parts of a building or where exit signs are far apart. All

signs have to work well in the dark and without main power, so NFPA 101 and IBC both have specific requirements for

backup illumination.


    Photoluminescent signs (aka “glow-in-the-dark signs”) are a useful technology for exit and egress signage. They

glow without a dedicated power source. Instead, they absorb the energy of light from normally well-lit surroundings—often a

particular wavelength of light—and release it over time as a glow. The brightness of their glow diminishes after the

charging light source is removed, but glow in the dark signs that are NFPA-, IBC-, and OSHA-compliant remain visible long

enough to get people to safety.


    Photoluminescent signs can be used as egress markers and exit signs as long as they meet the necessary performance

standards. Indeed, many egress markers (being smaller and more common than exit signs) must be self-

luminescent—electric illumination won’t do.


    PVC Signage


    Let’s be clear and as non-technical as possible in the description of

PVC signs. The chemicals and the molecular makeup

are the same as the pipe referred to in the opening of this article. The best way to help in differentiating the two as that

the signs are more lightweight and porous, meaning full of pores. How does this translate to what you want to know? With all

those tiny little pores in a PVC sign, it means it will accept liquids. In your case, it means they can accept ink, and

thus we can create graphics on the sign you want for your company.  


    PVC signs have a matte finish, which means it eliminates glare or reflection. It makes your graphics easier to read. If

you really feel you want a shinier gloss finish, we can do a decal print and affix it to your sign.


    Brushed aluminium signs


    If you’re looking for long-lasting outdoor signs, brushed aluminium material may be just what you need. They’re strong

but lightweight and are quite durable. They can be cut to any shape or size and is quite popular due to their resistance to

bending and water. What’s more, brushed aluminium signed to give your designs a stunning silver metallic finish.


    This type of material is great for both indoor and outdoor advertisements, as well as decorative pieces. It is often the

preferred option for wayfinding signs, making them perfect for offices, waiting rooms, or reception areas.


    Painted aluminium signs


    These are the same as brushed aluminium signs

, except they have a smooth, painted finish. These are made from two synthetic plates with a hard di-bond door. They

are extremely sturdy, yet surprisingly lightweight.


    We suggest using this material when designing a panel for a sale or special offer. Just like brushed aluminium, this

material is water-resistant and difficult to bend. This makes it perfect for outdoor promotion.


    When you’re designing a custom interior sign, you have several options for materials, including plastic, wood, glass,

and a handful of metals. Ideally, you’ll choose a material that best reflects your brand or the message of your sign. If

that material is stainless steel, you’re in luck. Stainless steel signs signal strength and industriousness to your clients. If your business is about offering

protection, stability, or innovation, stainless steel can help communicate that to customers. Plus, it offers five other

excellent advantages we’ll detail below.


    1. Eye-Catching Shine


    Stainless steel is a highly reflective metal that gives off a pleasant shine. It helps catch people’s attention,

especially when it is also the focal point of a room, as a lobby sign or other custom interior sign should be. If

you use stainless steel for an outdoor sign, a sunny day will charmingly light it up.


    2. Longevity


    As stainless steel is rust and corrosion resistant you can use it for both outdoor and indoor signs. You can expect a

long life out of these signs, as long as you occasionally maintain them. When you need to invest in a permanent sign that

will broadcast your brand for the long-haul, choose stainless steel.


    3. Cost-Effective Metal


    Stainless steel is quite cost effective as a sign material, especially as compared to other metals. Bronze, gold and

copper, or fake versions of these metals, can be more expensive. With a stainless steel sign, you get the benefits of

metal without the disadvantages.


    4. Completely Customizable


    Many custom indoor signs need to be just that, very custom. If you’re thinking of an unusual shape, unique

font or another uncommon design choice, stainless steel can be manufactured to fit your unique vision exactly.


    5. Just Add a Bit of Steel


    You don’t need to make a whole sign out of stainless steel. This material is a “neutral” that can be combined with

several other materials to great effect. Consider adding stainless steel lettering on a plastic sign or combining wood and

stainless steel for an industrial look. There are many other possible combinations that can work for your brand.

    AESTHETIC


    Acrylic signs are eye-catching yet subtle and tasteful. They are ideal for companies who are looking to add signage to

their office which is both practical and aesthetically pleasing. It’s even possible to “float” the letters of the sign to

create an attractive 3D effect.


    DURABILITY


    One practical reason why many people use acrylic signs is that they are very durable and need little maintenance. They

can withstand any weather condition including snow, rain, hail high winds and temperatures.


    CUSTOMIZABLE


    Although an acrylic sign includes a relatively simple and straightforward design, there is still room for a high level of

customization. The plate itself can be frosted, clear or even a solid colour. The design can include a simple name in a wide

range of colours, or even logo designs.


    BRANDING


    Acrylic signs offer an excellent

opportunity to improve the branding and brand visibility of your company. Acrylic signs allow for simplicity, which means you

are free to use whichever typography or imagery necessary to communicate your brand.


     


    PROFESSIONAL


    We offer a variety of different signage solutions, but when it comes to combining visibility and professionalism, acrylic

signs are the best solution and reflect the class of your company. Most signage is appropriate for B2C, but acrylic signage

is primarily for B2B companies.

    What is Resin Stone?


    Resin stones are made by taking shards of

stone, binding them with a strong adhesive and molding them in with a special resin. The resulting mixture is then capped

with acrylic or other coatings to ensure that the surface and core is protected and scratch resistant. And, because it is

made from resin, the material is much lighter than normal stone without losing it’s durability.

    What common items are made from Resin Stone?


    Stone resin can be formed to make a number of common home items such as tile for flooring, bathtubs, sinks,

showers, garden stones and even some jewelry as well.


    What are the benefits of Resin Stone?


    In addition to being lightweight and affordable, there is a reason this material has a bit of an edge when compared to

other commonplace bathtub materials such as acrylic, fiberglass, porcelain and cast iron. The material will not warp

overtime unlike fiberglass and acrylic, nor will it break, shatter or chip due to heavy impacts from accidental drops or

falls like porcelain will and, as stated before, the material is as durable as cast iron with being four times lighter than

it. It is non-porous, meaning it will not absorb water unlike fiberglass and acrylic, which means the structural integrity of

it will never change, it also has excellent heat retention on par with higher end materials like enameled steel and copper.

And lastly, stone resin is very eco-friendly, made from recycled materials with an entirely green production model. With the

added benefit of being a durable material, it will also not create waste as stone resin bathtubs will last several lifetimes.

    How to clean and maintain Resin Stone


    Surprisingly, stone resin is also quite easy to maintain and clean, as most stains or dirt can be washed away with

water and can also be polished easily as well. Simply use a soap based solution or any non-abrasive cleaners to remove any

buildup or stains down the line. Avoid using acidic based cleaners or abrasive cleaners as it will damage and remove the

finish over time.

    How long does Resin Stone last with good maintenance?


    With good care and proper maintenance, stone resin can last a lifetime easily.
