Applications of RTV-2 molding silicon rubber

 RTV-2 molding silicon rubber is mainly applied for making various molds,such as reproduction of poly resin, epoxy, polyurethane-polymer, plaster, gypsum, soaps, candle & lighting, architecture, decorative arts and crafts, plastic toy, gift and stationery, big statue, cultural relic product, etc..

Good tensile and tear strength, high reproduction times and with resistance of high temperature, etc.

 

 

Step One:Take 100g of part A and add 2g of part B and mix the silicon rubber and the curing

agent evenly.

Note:Molding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent. Remember to mix part A and

part B evenly, otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What's more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber materials.

Step Two: vacuum pumping

Without exception, this takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step Three: Brushing cast & Perfusion Molding operation
