Product Description
Description
Prototype rubber silicone and shoe mold rubber silicone are both condensed two-component room temperature vulcanized silicone rubbers, which have the characteristics of low viscosity, invariance, and low linear shrinkage, which are suitable for the replication of small batch products.
Features
A. Mainly used for shoe soles mold making
B. Two-component silicone rubber with tin-catalyst
C. Cured under room temperature
D. Low shrinkage
E. Excellent fexibility & easy demould
Application
For Prototype rubber silicone: widely used in Prototype models, PVC plastic molds, cement product molds, low melting point alloy molds, alloy toy crafts, plastic toys, electronic crafts, stationery industry, large statues, reproduction of cultural relics, (shoe molds) soles Model development and design for mold manufacturing, pad printing positioning, and earthquake resistance of electronic equipment.
Using Instruction
The component A of shoe Mold Silicone Rubber is white flowing liquid and the component B is the curing agent. For example,
take silicone rubber of 100g and add 2% curing agent for mixing evenly. After the silicone rubber and the curing agent are
completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid
silicone rubber into the product to be duplicated or into the mold frame.

Attention
Shoe mold silicone rubber is used for pouring or brushing technique. That is to say, fix the product or sole model to be duplicated onto a plane plate, then enclose the plane frame with wooden plates to prevent the leakage of the silicon , mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model, then brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.
