RTV-2 Liquid Silicone Rubber Platinum Cured Resin Crafts Moulding Silicone
Product description
MCPLA-L20 A/B two-component addition cured silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a flexible rubber. 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. Polymerization occurs without formation of heat.
What are the Advantages of MCPLA-L20A/B RTV-2 platinum cured 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.
#High Temperature Resistant: MCPLA-L20A/B is suitable for casting resin crafts with Temperature Resistant property.
What are the Applications of MCPLA-L20A/B RTV-2 platinum cured silicone rubber
First: making many kinds of molds:
1.Low melt metals (mold life can be short), Cement, Concert,concrete stones, wax molds, PU molds, resin molds, gypsum casting, candle molding, chocolate , candy and any other food product mold making, prototyping etc.
2.Making molds for food grade products: chocolate molds, cake molds, sugar molds,ect.
3.Making molds for life casting: real hand molds, real feet molds, prosthetics ect.
