RTV2 Translucent Platinum Cured Liquid Silicone Rubber For Epoxy Resin Mold Making
MCPLA-L20 Two-component addition type Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a Shore A20 rubber. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a translucent, elastic and resistant material. Polymerization occurs without formation of heat.
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 guarantees the products confirms with the sales Specification.
