Application of Rtv Liquid Moulding Silicone Rubber

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

Features of Rtv Liquid Moulding Silicone Rubber

RTV liquid moulding silicone rubber has the following features

a. low viscosity, exceptional fluidity and easy operation : 21000 cps suitable for pouring
b. resistance to deformation, high-temperature 220 degree centigrade
c. acid, alkali and ageing-resistance
d. low shrinkage< 0.2%
e. good tensile strength 36±2 (kgf/cm)
f. high reproduction times

Operation instructions

Step 1: prepare the original molds

Make sure your original molds perfect. fix it on a board. And fix the original mold on a board , then used four piece of board to enclose the original molds .

Step 2: Take 100 G parts A and add 3G parts B and mix them evenly.

*Notes: Mold making silicon rubber is a kind of flowing liquid ,it contains two parts. Part A is a kind of flowing white liquid and part B is the curing agent or catalyst .Pls follow the step strictly:

1.Weigh the two part exactly by electronic weight..

If not , for example add two much catalyst , the operation time will be too fast to operate ,which will cause inconvinience to operate .

2.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 molds will meet a short life. All of these will cause a waste of silicon rubber.

Step 3: Vacuum pumping

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

Step 4: Pouring casting or Brush operation

*Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .

2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .

3. We sugges to set the silicone mold for another 12 hours after demould before put into large production
