Gypsum and Concrete Mold Making RTV 2 Silicone Rubber

Brief Introduction 

Product Description

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 Gypsum and Concrete Mold Making RTV 2 Silicone Rubber:

 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.
