Description MC Silicone addition cure molding silicone rubber is a two component 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 transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Features High Transparency
High tear and tensile strength
Long shelf life with low shrinkage
Easy mixing
ApplicationsLabel manufacturing, Molding applications requiring low shrinkage e. G. Toys, jewelry, automotive, rapid prototyping etc.

Using Instruction1-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.
Storage & Shelf lifeWhen 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.
Packaging & Shipping| Part A base silicone | 5kg, 20kg/drum, 25kg/drum or 200kg/drum |
| Part B CA30 Curing Agent | 250g, 800g/bottle, 1kg/bottle |
