GRC Casting Silicone
Product Descritpion:
GRC Casting Silicone is wonderful to make molds either with simple or intricate patterns, such as GRG(Reinforced concrete), GRC (glass-fiber-reinforced gypsum), cement and other decoration architectural products etc. With good resistance to heat, deformation, acid & alkali and expansion, finished silicone molds serve very good performance in reproduction process with every fine detail on designing models.
Appearance:
Part A: Silicone Rubber is an white liquid Part
B: Catalyst is an non-toxic and odorless liquid in transparent color.
ATT: we can provide catalyst of Fast, Medium,Slow for hot ,cold, warm season.
