Glow Worm™ Pigments

For best results, use Glow Worm™powders with a fast-curing translucent resin such as Smooth-Cast® 325. The fast curing resin allows uniform filler dispersion throughout the finished casting. If the resin system is too slow, fillers may settle unevenly in the finished casting.Glow Worm™ powders can also be added to translucent / clear silicone rubbers such as Dragon Skin™ or EcoFlex™ Series for glow in the dark props that are soft and flexible. Glow Worm™powders can also be blended to create additional finished effects.

Directions for Use – Pre-mix all liquid resin, rubber or foam before dispensing. Store and use all materials at or near 23°C. Glow Worm™ powders must be kept dry (see ’Guarding Against Moisture’ section). Use with adequate ventilation. Read and follow directions for material used to mix with Glow Worm® powders. The following example features SmoothCast® 325 (A+B) mixed with Glow Worm® powder. The powder must be thoroughly dispersed into a two component liquid resin or rubber to a uniform consistency.

Recommended Mix Ratio by Volume: 1A + 1B + 1 Part Glow Worm™ powder.

By Volume Mixing & Casting Procedure:

1. Dispense 1 cup of Smooth-Cast® 325 Part B into a clean mixing container.
2. Dispense 1 cup Glow Worm® powder into mixing container.
3. Mix thoroughly.
4. Dispense 1 cup of Smooth-Cast® 325 Part A into mixing container.
5. Mix for 30 seconds until all filler particles are dispersed and pour into rubber mold.

Lower Your Cost Per Casting - Glow Worm Powders are Expensive: Mix small amounts as directed above and brush layers into a mold to coat the mold cavity (known as a face coat or gel coat).

Optional: Combine Smooth-Cast™/Glow Worm™ mixture with 1 part Ure-Fil™ 11 to increase brushability of gel coat. Follow by backfilling with straight resin or foam.

The glow effect will be the same vs. a solid casting and material cost will be greatly reduced.

Guarding Against Moisture – All powders will absorb atmospheric moisture over time which will react with urethane resins. If you notice a moisture reaction between resin and powder or suspect that your Glow Worm™powder contains moisture, you can remedy by spreading powder evenly over a metal cookie sheet at ¼” (0.6 cm) thickness and bake in oven for 4 hours at 150° F/60° C. Allow to cool before mixing powder with resin. Store powder in a tightly closed container in a cool, dry environment with a desiccant pouch (available at your local hobby/arts and crafts store). Replace used desiccant pouches every other time you open container.

Glow Worm™ Powders are up to 50% brighter than the competition.
