FAQ
FAQ OF Tin cure silicone rubber for making silicon models:
1. Why will 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 can destroy 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 or 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.)
2. Why does the silicone mold appear to dry outside but wet inside?
Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.
Solution: Add 0.1% water into the silicon rubber and Stir over a low speed briefly when you use it.
3. Why is the tear strength of the silicone mold weak?
In order to reduce the viscosity of silicone rubber, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, adding silicone oil might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.
