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..
Features of RTV-2 molding silicon rubber
Good tensile and tear strength, high reproduction times and with resistance of high temperature, etc.
Operations for molding silicon rubber:
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
