RTV2 Translucent Platinum Cured Liquid Silicone Rubber Epoxy Resin Mold Making
MCPLA-L Series Platinum-cure liquid silicone rubber also known as addition-cure silicone mold rubber. It is called "platinum cured" because it uses a platinum catalyst to initiate the curing process. After mixing the two components liquid, RTV-2 platinum silicone rubber will cure into a translucent, elastic and resistant elastomer at room temperature,platinum silicone exhibit the lowest long-term shrinkage and have long library life,which are good for making molds for casting a variety of materials, like polyurethanes, epoxy resin, plaster, concrete,candle molds.
Applications of Platinum Cured Liquid Silicone Rubber Epoxy Resin Mold Making
#Polyurethane, Epoxy resin and other reactive resins molds
#Small pieces of cement,plaster,gypsum,concrete products.
#Food like chocolate,fondants,desserts
#Wax,candle,soap;
#Life casting,casting body parts,prosthetics.
Features of RTV2 Translucent Platinum Cured Liquid Silicone Rubber
#Easy to Operate : Due to the Room Temperature Cured feature and Low Viscosity, It's easy to use platinum liquid silicone rubber for your DIY Projects at home.
#High Strength: RTV2 platinum cure silicone rubber has a high tear strength, making it ideal for making complex molds that require multiple demolding times.
#Easy Release: RTV2 platinum cure silicone rubber has excellent release properties, which means that the mold or casting can be easily removed from the mold without causing damage to the final product.
#Bubble Free : Due to the low viscosity of MCPLA-L20A/B platinum silicone and long working time , the silicone could release the bubble itself.
#High Temperature Resistant: RTV2 platinum cure silicone rubber is suitable for casting resin crafts with Temperature Resistant property.
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
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.
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.
