Glow Worm® phosphorescent powders can be added to Smooth-On liquid plastics, rubbers and foams to create castings that glow in the dark after being charged with light. Choose from either green or blue.
What sets Glow Worm® powders apart from other glow-in-the-dark powders? Used as directed and after being light charged as recommended, castings made with Glow Worm® powders will glow in the dark at least 10 times longer than other glow powders.
Glow-in-the-dark castings are used for Halloween theming displays, home hobby projects, aquariums, store displays and more. These materials are also used for industrial marking, municipal safety applications and more.
