Making outer skin for models by brushing skin-safe silicone

Making outer skin for models by brushing skin-safe silicone Operations of Platinum cure silicone rubber Step One: Preparation of the Model Firstly, you should deal carefully with the Model, you want to be molded. If no polishing of the Original mold or the products you want to be molded, the surface of it is not so smooth or perfect, then the products made out of silicone molds will be not up to standard. Step Two: Take 100g of part A(silicone rubber) and add 100g of part B(curing agent) and mix two parts evenly. Notes1: Molding silicone rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of translucent flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber. Notes 2：the weight of the silicone and catalyst should be weighted correctly. Step Three: vacuum pumping Without exception, this step takes about 2-3mins,less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available. Step Four.Brushing cast: a. Evenly brush the mixed silicon rubber on the product which is covered with mold spray with a brush or a brush pen. b. After the cross linking reaction (about 30 minutes), brush a second coat which can increase the tension and tear strength of the mold. c. 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. d. Cover a third coat. (Note: if you have high requirements for the tension and the tear strength for the mold, please repeat step c and step d. Hence, the finished silicone molds will have a good quality and a longer life, which can help you save cost and increase production efficiency.)
