Product Description

Product Description of silicone rubber

RTV-2 silicone rubber is generally named as two-part room temperature vulcanized silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.

Using Instruction of silicone rubber

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.

 
Storage & Shelf life of silicone rubber 

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.
