fda platinum cure rtv2 guochuang silicone rubber for candy molds

It is a two-component platinum cure silicone rubber which can be cured at room temperature and also can be heat cured.It is colorless oily liquid and becomes soft elastic material after vulcanization, it is good for molds making

food grade GC silicone rubber SP-820 for candy cake molds

1.FDA & ROHS certificate.
2.No limitation with product thickness .Can do deep curing .
3.High temperature resistance (can reach 0~250 degrees ) ,acid and alkali-resistance and aging resistance
4.Light viscosity and good flowability .easy for pouring operation .
5.Can be cured both at room temperature or be heated
6.Low shrinkage.Not releasing low molecular during cross-linking process .So the volume is constant .The shrinkage rate is less than 0.1%.
7.Favorable tensile and tear strength
8.High duplication times .aging -resistance
9.Tasteless.no flammable,safe and reliable
10.Customize as you need

How to Use

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:

Evenly brush the mixed silicone rubber on the product which is covered with mould 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 mould.
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.
