1, b component is a catalyst, easy to moisture hydrolysis, so the lid should be used after the cover tightly.
2, a, b group once mixed, chemical reaction; immediately start, viscosity gradually rise, can not be suspended, in order to avoid waste, should be used according to the amount, with the match, should be used immediately after the match, can not be delayed.
3, a, b group ratio, related to the speed of the chemical reaction and the performance of the mold. b component more, the faster the reaction, the higher the strength and hardness of the product, but the toughness with the reduction, therefore, weighing requirements are accurate.
4、 Before preparation, the a component material should be stirred up and down evenly, and then weighed.
5、 The pouring method is suitable for the relief class, and the painting method is suitable for the production of three-dimensional class molds. Pouring relief class mold should be made first length and width are larger than the original carving length and width of 4-6cm border. The border should be flat and the inner surface should be smooth. When pouring, place the frame on a clean glass plate, and then place the original in the frame, leaving a gap of 2-3cm on each side.

Because unsaturated resin and resin products with peroxide curing agent after the reaction of resin will generate a lot of heat, the general resin curing time of 3 minutes, so 3 minutes after the mold as soon as possible, in order to prevent the silicone mold will not produce the phenomenon of burning mold.
Why does mold silicone have a low number of mold turnovers?
In the process of making the mold added too much silicone oil, silicone oil destroyed the molecular weight of silica gel, so the mold will appear to turn the mold less times not durable and other phenomena. If it is said to do small products with more complex patterns
