Translucent Platinum Liquid Silicone Rubber 25 Shore A For Urethane Resin Molds
Product description
MCPLA-L25 A/B two-components addition type silicone rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a 25 Shore A 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.
Applications
1. A range of materials can be cast into the cured silicone mold:
Polyurethane, Epoxy resin and other reactive resins
Small pieces of cement,plaster,gypsum,concrete products.
Food like chocolate,fondants,desserts
Wax,candle,soap;
Low melt metal
2. 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. In order to preserve best properties it is recommended to follow strictly the following guild lines:
Store the original packing tightly sealed and at a temperature below 30 degree Celsius.
Use the product as soon as the packaging has been opened.
