Features of   casting materials and mould making 

RTV-2 mould making silicone rubber for molding is white or translucent flowing liquid with general hardness of 22-50shore A after curing. Molding silicone rubber is a kind elastic silicone 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, Stripping the gender is good, Linear shrinkage rate low, Size stability is good.

Note: according to user's requirements, production, commissioning, different color and performance products

FAQ of   casting materials and mould making 

Why should the silicone mold be reused only for a few times?

It can be due to the following reasons:

a. Adding too much silicone oil in to silicone rubber.

b. Using the silicone rubber with a high hardness to make molds for small sized products

with delicate and intricate designs .

Silicone rubber using instruction on 

Data of    casting materials and mould making 

Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2g curing agent for mixing evenly (silicone rubber and curing agent must be measured accurately). After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. If you don't have vacuum machine, please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself. Since the less curing agent you add, the slower the mould will curdle, the bubbles will bubble out itself.
