#RTV2 Translucent Platinum Cured Liquid Silicone Rubber Mold Making
MCPLA-L Series Platinum-cure liquid silicone rubber also known as addition-cure silicone mold rubber, two component elastomer cross-linking at room temperature. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured into translucent, elastic and resistant material. platinums silicones exhibit the lowest long-term shrinkage and have the longest library life of all mold rubbers . While good for making molds for casting a variety of materials.

Processing and Instructions of Addition Cured Liquid Silicones Rubber
Step 1
The ideal working temperature is around a constant 25°C. Best
results can be obtained at constant temperatures between 21°C and
26°C, in a clean, dry, dust-free environment. Avoid working in high
humidity.
Step 2
Measure product in accordance with your intended use. Prepare 1
part A to 1 part B by weight and pour into a clean, smooth-sided
container large enough to hold all the liquid and allow room for
mixing.
Step 3
The material must be mixed thoroughly for at least 5 minutes. make
sure to scrape the container sides, bottom, and corners as you mix.
Be careful not to whip excessive air into the mixture.
Step 4
Prepare a container(not silicone material),add the item and keep
them face up.
Pour the mixed silicone onto the container and distribute evenly to
cover the top of the item by at least 6-7mm
Step 5
Adjust the position and then let it cure, the bubbles will melt
gradually.
Step 6
Pull the item out of the mold
Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.
Storage and shelf life of Addition Cured Liquid Silicones Rubber
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.
