Product Description

RTV-2 mold making silicone rubber is generally named as two part silicone rubber that vulcanizes at room   temperature.Part A is a flowable liquid ,part B is the catalyst. 



  • 1.Good characteristics of easy-operation
  • 2. Light viscosity and good flowability
  • 3. Low shrinkage
  • 4. Favorable tensile and tear strength
  • 5. High temperature resistance ,acid and alkali-resistance
  • 6.High duplication times
  • 7.Vulcanize at room temperature
  • 8.Easy for demoulding
  • 9.No smell ,non-flammable ,safe and reliable



Making molds for


  • Cultural relic duplication, architectural decoration, statues 
  • Resin crafts ,climbing holder
  • Lighting ornaments, candles, hand soap
  • Plaster, Gypsum, Cement, Concrete decorations

Step One: Prepare and clean the prototype.

You must make sure your original molds perfect.

Step Two: Mixing part A and part B evenly

Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Step Three: 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 Four: Pouring cast or brushing cast

After released the bubble, we can pour/brush the silicone rubber on the prototype 

Pouring cast:

It is suitable for simple products with the smooth surface. Without any mold lines, which helps you save time and is easy for operation. Evenly and slowly pouring the mixed silicone rubber into the square frame. After the cross linking reaction and the silicone rubber turns dry, you can take the products out. Thus, the mold has been done.

Brushing cast:


  • Evenly brush the mixed silicone rubber on the product which is covered with mold spray with a brush or a brush pen.
  • After the cross linking reaction (about 30 minutes), brush a second coat which can increase the tension and tear strength of the mold.
  • Cover a glass cloth on it after another 30 minutes of a second cross linking reaction, and use a brush pen or a brush to avoid any interstices.
  • Cover a third coat.
