Creative Expression with Glowing Resin

A Guide to Glow Resin Types and Usage:

How do you maximize design features and performance using luminescent Glow in the Dark resin?

We are often asked about resin colors, attributes and available forms.  Our unique resin provides the greatest range of design options. We will touch on a few basics to help sort out your brightest choices. 

The Glowing Crystal Element
Crystal-White-300x276It all starts with glow crystals!

The active ingredient in high performance glow in the dark technology is our proprietary glow crystal. The best crystals absorb most forms of light storing them as energy, and then emit a glowing illumination in near to full darkness.  The glow crystal material is sometimes called glow powder or pigment, although technically neither term is exactly accurate.

Depending on the requirements of the project, we work with varied types, grades and sizes of glow crystals, but all behave in the same basic way.  High performance photoluminescent crystals absorb light (energy) from natural sun or room light, then emit light for many hours until recharged.

The crystals themselves are very hard like tiny diamonds. To improve processing, glow crystals should be evenly mixed or encapsulated into a clear base medium. The clear base resin is the carrier for the glow crystals and may add required properties. Once the crystals are incorporated into the clear base, the mixture can be integrated into actual designs and processed into finished glowing pieces.

Epoxy Resin and Glow Crystals

The term “resin” has multiple meanings that include both clear epoxy resins and the plastic resin pellets used for injection molding and extrusion.

Clear epoxy resins (also known as casting resin) is typically used as a protective coating for sculptures and statues, in jewelry making, or to protect artwork and paintings. Epoxy resin is a two-part system that includes mixing a liquid base with a hardening agent. When the two parts are mixed, a chemical reaction causes the material to cure and harden.

Glow in the Dark Plastic Resin Pellets

Using our special processes, we encapsulate high quality glow crystals into plastic resin polymer. This ensures consistent processing of the resin pellets for injection molding, extrusion or rotational molding applications. The quality and concentration of glow crystals determines both light output and longevity of the glow. This can be tailored to meet or exceed specific project parameters. For example, a formula that is loaded at 40% glow load level will emit a visually stronger glow output than a formula mixed in a ratio of 20% glow crystals, assuming the crystal quality is the same.

Most common base resin materials can be used as the carrier, such as ABS, Polypropylene, TPE, EVA, HDPE and more. It is best to start off with the clearest possible resin material. This allows the glow crystals to achieve optimum results and absorb/emit light in an unobstructed fashion.

Glow resin materials are available as either a concentrated master color batch to mix with your own base, or as a fully pre-mixed custom order ready to run.

Original glow in the dark materials were only available in a neutral or pastel daytime color. With recent breakthroughs in technology, illuminating resins are now available with vibrant day and nightglow color combinations, including new Neon Brights.

Prototyping and Home use

Custom compounded plastic resin pellets are intended for use with injection molding, extrusion or blow molding operations in a professional setting.

This means the Resin pellet material is meant for processing in professional injection molding or extrusion equipment in a production environment. This type of equipment heats the small pellets to a very high melting temperature so it can be poured into a mold or extruded. Once the resin cools, the completed shape is ready for further assembly.

We occasionally receive requests from customers asking if they can creatively replicate this process using home equipment such as a stovetop. Their one of a kind projects are usually for making a prototype or creating finished products like jewelry. We do not recommend this approach, as the plastic resin material is not intended for home stoves or cookers.

While there are a few videos online showing melting resin pellets at home on a stove or in an oven, this technique can create serious issues with smoke and fumes. Prolonged exposure to fumes emitted during the melting process can be dangerous. Despite our warning, if you attempt this at home please use a very well-ventilated area.
