Molding methods and Making silicone molds Instructions

Specific methods can be used bags, brush, filling one of the action, the process is as follows:
　　1 package mold: complex modulus silicone fluid is flowing white, two two groups: A group is a silicone, B is the curing agent, for example, 100 grams of silica gel with 2% hardener stir, pour finalists good mold species inside, put evacuated vacuum machine, vacuum smoked plastic mold naturally cured cement products.
　　2 brush mode: the product first before brushing or brushing a layer stripping machine model, then brush evenly coated silicone surface of the product. After waiting 30 minutes, pasted on the surface layer of fiberglass cloth to increase strength, then in the second city of silica gel coated silicone dry, do the outer membrane, the outer membrane can be applied plaster or resin and other materials.
　　3 irrigation mold: Mold around cement products, with an offset or glass enclosed, the smoked vacuum silicone directly into the products above, upon drying silicone molding, remove the product, mold on the shape (mold filling generally use relatively soft hardness do silicone membrane, so that stripping is easier, will not damage the silicone mold inside the product).
　　PS Note: a note the amount of curing agent, curing agent dosage should be depending on temperature, high temperature decreased. Curing agents used in excess, will die hard and brittle; curing agent is too small, the operating time will be extended. b To prevent mold silicone physical changes, it is recommended not to add silicone oil. The best c die after re-use in one day, in order to achieve better results.
