2. high reproduction times
3. good tensile strength

Detailed

tin-catalyized silicon

 

Model: HY620 RTV-2 tin-catalyized silicon rubber

HY620 tin-catalyized silicon application

for small size of PU/poly resin, unsaturated resin, plaster, candles and gypsums crafts, toys, soap, statuary ,casting molds making,etc.

 

tin-catalyized silicon description

 

tin-catalyized silicon rubber is white or red flowing liquid with general hardness of 22-50 shore A after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

FAQ. Why the tin-catalyized silicon rubber just can be reproduced for a few times?

It can be due to the following reasons: 

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs. 

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
