Product description
Two-component addition type silicone rubber is a two-part, platinum-catalyzed, liquid silicone system that cures at room temperature. 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
Convenient to operate because the RTV property
Easy to mix due to the low viscosity (7000~9000Cps)
High duplication because of high tear and tensile strength
Long shelf life with low shrinkage
Can be accelerated for rapid cure
Applications
casting polyurethane and other reactive resins molds
casting Small pieces of cement,plaster,gypsum,concrete products molds
Food like chocolate,fondants,desserts
Wax,candle,soap;
Low melt metal
Processing and Instructions of Addition Cure Silicones
Note:
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 -L 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.
