Translucent Platinum Silicone Rubber RTV2 For Resin Crafts 25 Shore A
Two-component addition type silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A25 rubber. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Features
Food grade, Skin Safe (SGS FDA certificate)
Easy to use due to Low viscosity(7000Cps)
High casting times with high strength
Temperature resistant
Applications
Polyurethane, Epoxy resin and other reactive resins molds
Small pieces of cement,plaster,gypsum,concrete products.
Food like chocolate,fondants,desserts
Wax,candle,soap;
Low melt metal
Life casting,casting body parts,prosthetics.
Processing and Instructions of Addition Cure Silicones
Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.
Storage and shelf life
MC Silicone MCPLA -H Series should be used within 12 months from
the manufacturing date. Beyond this date, MC silicone no longer
