Applications of RTV Silicon rubber :
Liquid RTV Silicon for Molds Making Applications is suitable for industries such as toys, gifts, decoration, plate engrave, human replica, art crafts, resin crafts, poly resin crafts, unsaturated resin crafts, candle crafts, plastic crafts, stationeries, plaster crafts and Buddhist statue crafts.
Working techniques of RTV Silicon rubber:
According to the different materials, two series of mould making silicon rubber are divided, which are HY-6 and HY-7.
A. HY-6 Series includes model codes of HY-620, HY-640, HY-628, HY-638 with the hardness of 18-22 shore A, 38-42 shore A, 25-30 shore A and 35-40 shore A respectively.
HY-620 and HY-640 are particularly suitable for pouring mould.
HY-620 is for small crafts mould making, while HY-640 is for large crafts mould making. Common features of HY-620 and HY-640: Light viscosity, pourable effort, good fluidity, easy-operation, good tension and high tear strength.
HY-628 and HY-638 are particularly suitable for brushing mould making.
Common features of HY-628 and HY-638: Moderate viscosity, easy-operation. Agents are available if requested. It wont affect the quality of silicon rubber but to make the operation much easier.
B. HY-7 Series includes model codes of HY-718, HY-728, HY-738 with the hardness of 15-20 shore A, 25-30 shore A and 35-38 shore A respectively.
HY-718 is a kind of soft silicon rubber and suitable for pouring mould making of small crafts.
HY7-28 with moderate viscosity is suitable for pouring mould and collapsible mould making of crafts in medium size.
HY-738 with high hardness is suitable for to collapsible mould making of crafts in large size.
FAQ of RTV Silicon rubber :
1. Why could 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. )
2. Why does the silicone mold get burnt out?
This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.
3. Why does the silicone mould appear to be 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 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.
