Frequently asked questions of Silicone RTV2 for mold making 

 1. 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 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.)

Operation Instruction of Silicone RTV2 for mold making

1. Silicone RTV2 for mold making is applied to small products or products with fine patterns. The mold  for the fine detailed and small products should be made of soft silicon to protect the products from easy breaking when demoulding.

2. Silicone RTV2 for mold making: If large product duplication or fabrication, the mold should be made of higher hardness silicone rubber so that the products made will not deform.
