RTV-2 mould silicon rubber
HY615 RTV-2 mould silicon rubber application
Model: HY-615 RTV-2 mould silicon rubber Usage: Silicon rubber for PU/poly resin, unsaturated resin, plaster, candles and gypsums crafts, toys, soap, statuary ,casting molds making,etc.
This product RTV-2 mould silicon rubber is a white or red flowable liquid with a hardness of 22—50A° 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.

FAQ. Why the RTV-2 mould 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.)
