Poly GlassRub 50 Clear Liquid Rubber

platsil-71-40Poly GlassRub 50 liquid rubber is an easy 1:1 mix system designed for making clear molds that can be cut away from a master with less chance of damage and better seam positioning since objects are visible through the rubber. In addition, GlassRub is used to make decorative rubber castings and art, as well as for encapsulating objects for intriguing display applications. With the addition of PolyColor dyes, GlassRub can be used to create transparent parts of any color.

Cured GlassRub may yellow slightly over time if exposed to UV light sources (florescent bulbs) and can be mixed with PolyColor dyes to mask this effect.
