Rtv2 liquid tin cure silicone rubber to make mold 

Description  

Two-component silicone, tin-curing, flowable, vulcanizes at room temperature. Can be used for a long time in the temperature range of - 65 ° C - 200 ° C and keep its soft and elastic properties.

Application

General mold making.

Suitable for reproducing and replicating products in large quantity for industries: Art crafts, sculptures, furniture, architectural elements, garden ornaments, tire, soap, candle and so on.

Used for making molds for variety of material, such as resin, PU, gypsum, plaster, concrete, cement, stone, GRC, PVC, polyester, wax, bronze and so on.

Operation instructions

1. Mix part A and pars B evenly with 100:2 mixing ratio.

Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.

2) Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and waste silicon rubber.

2. Vacuum pumping

Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture successfully, so as to ensure that there will be no bubbles in the finished mold.

2) This step is less than 10 minutes. Otherwise, it will cause cross-linking reaction, and no more further steps will be available.

• Pouring casting or Brush molding

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

2) For delicate pattern products we s est 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 s est to set the mold for another 12 hours after demould before put it into large production.
