Epoxy Resin Mold Making RTV2 Platinum Silicone Liquid Rubber Tensile Strength 4.2-4.8 Mpa Linear Shrinkage ≤0.1%

MCPLA-L Series Platinum-cure liquid silicone rubber also known as addition-cure silicone mold rubber, two components 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 a translucent, elastic and resistant material. platinum silicone exhibit the lowest long-term shrinkage and have the longest library life of all mold rubbers which are good for making molds for casting a variety of materials, like polyurethanes, epoxy resin, plaster, concrete,candle molds.

Features of MC RTV2 Translucent Platinum Cured Liquid Silicone Rubber
-Totally non-toxic, odor-free,and eco-friendly
- High strength; good tensile strength and tear strength
- Very suitable hardness
- Low shrinkage less than 0.1%
- Good flexibility, very Stretchy
- Excellent UV-irradiation resistance and aging resistance

Applications of Platinum Cured Liquid Silicone Rubber Mold Making
1.mold making for various materials.
polyurethane and other reactive resins, epoxy resin molds making
Small pieces of cement,plaster,gypsum,concrete molds making .
Food like chocolate,fondants,desserts molds making
Wax,candle,soap molds making

2.Life casting, making prosthesis , artificial skin, silicone dolls ,shoe insole.

Processing of Addition Cure Silicones Liquid 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


Note:
Contamination from sulfur (e.g., sulfur-based clay), amines, tin compounds, cured polyester resin, some paints and some silicone rubbers may inhibit surface cure of platinum-cured rubbers.

Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.

When the silicone rubber is stored at or below 25 degree Celsius in the original unopened containers, Silicone Base and Curing agent have a usable life of 12 months from the date of production. After 12 months' stockpiles, please use tool to stir the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
1.Store the original packing tightly sealed and at a temperature below 25 degree Celsius.
Use the product as soon as the packaging has been opened.
2.Close the lid tightly after taking out the proper amount of liquid silicone rubber.
