Rtv-2 Platinum Cure Silicone Liquid Rubber Life Casting Silicone Food Safe
MCPLA-L20A/B RTV2 platinum cured liquid silicone rubber is a two-part, high-performance elastomer that is used for mold making, casting, and other industrial applications. It is called "platinum cured" because it uses a platinum catalyst to initiate the curing process, which results in a higher quality and more durable end product.
Applications of Platinum Cured Liquid Silicone Rubber Resin Mold Making
1.mold making for various materials
polyurethane and other reactive resins
Small pieces of cement,plaster,gypsum,concrete products.
Food like chocolate,fondants,desserts
Wax,candle,soap;
Low melt metal
2.casting body parts,artificial skin,shoe insole.

-Totally non-toxic, odorless, harmless, and eco-friendly
- High elasticity; good tensile strength and tear strength
- Very suitable hardness
- Low shrinkage less than 0.1%
- Good flexibility, permeability and easy operation
- Excellent UV-irradiation resistance and aging resistance
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.
