ornament, planter,furniture decorative etc.)
Step One: Prepare and clean the prototype. You must make sure your original moulds 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 a cross-linking reaction, and no 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 a smooth surface. Without any mould 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 mould has been done.
Brushing cast:
1. It is a kind of non-dangerous goods. This product should be sealed and placed in a cool and dry place which should keep from sunlight and rain .
2. The shelf life is 12months from the date of production.
It can be reused after reinspection when it exceeds the storage period.
The rtv2 silicone rubber is light viscosity and good flowability for easy-operation .It is low shrinkage
,favorable tensile and tear strength ,high temperature resistance ,acid and alkali-resistance for resin craft molds casting
