Two-Part RTV Liquid Polyurethane Rubber For Making GRC Molds
Description of Liquid Polyurethane Rubber:
Product Description
There are many different formulations of polyurethane rubbers for mould making. The polyurethane casting rubber can be pure or filled with special mineral charges. Are available different hardness from 35 Shore A to 80 or 90 Shore A.
Applications of Liquid Polyurethane Rubber for Making Wall Block Molds:
Applications
A: Cultural relic duplication, architectural decoration
B: Resin crafts
C: Picture frames, concrete blocks
D: Plaster, Gypsum, Cement decorations
F: Model design, product exploitation, etc.
Applications are the realization of models, the encompass of electrical circuits or capacitors.
The new formulation into the polyurethane rubber family products is a transparent bi-component pouring rubber for different applications such us the encompass of objects. The rubber is transparent like the glass with no yellowing tendency.

Using Instruction
1-Take 100g of part A and add 100g of part B and mix the silicone rubber and curing agent evenly.
2-vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available
3-Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.
