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

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. Especially note that the silicone should not touch or mix with compounds including nitrogen, phosphorus, sulfur, tin, lead or metal organic acid.
3. Addition cure Silicone RTV-2 is an environmentally-friendly liquid silicone product is not easy to burn which can be stored and transported as non-hazardous goods.
4. The shelf life is 12months from the date of production.
It can be reused after reinspection when it exceeds the storage period.
It is low viscosity ,good tensile and tear strength ,high duplication times and aging -resistance for candy mold making
