Liquid RTV silicone rubber for gypsum mold

1.Model: HY-625 to HY-640 condensation silicon rubber

2.Usage of Liquid RTV silicone rubber for gypsummold :

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

3.Description of Liquid RTV silicone rubber for gypsum mold:

This product is a white or red flowable liquid with a hardness of 25—40A° when cured. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

5.FAQ of Liquid RTV silicone rubber for gypsum mold:

Why the condensation silicon rubber mold 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.
