USING INSTRUCTION
1-Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
2-vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available
3-Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.
APPLICATIONS
MC RTV-2 mold making silicone rubber are suited for casting a wide range of materials Polyester/ Polyurethane/ Epoxy resin, gysum/ plater, cemetns/ concrete , wax , Jewelry, Food grade for chocolate, shoe insole, etc.
Package
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
Certificates
Storage
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
RTV-2 silicones are specifically designed to replicate stones, marble, wood, and other construction materials, producing outstanding fidelity for every detail, including veins and surface texture. The various grades of architectural molding silicones enable builders to replicate accurately the look they desire while providing long mold life and excellent resistance against casting materials.
Benefits of MC Silicone
Ease of processing
High resin resistance increasing the number of cast parts
Low linear shrinkage for greater accuracy
Easy release of shapes, including large pieces and complex geometries
High compatibility with water-rich casting materials such as gypsum
Increased compatibility with high performance concrete
Dimensional stability due to very low shrinkage
High mechanical properties over a range of flexibility
