Liquid silicone rubber has one component and two components, and the need to use platinum catalyst is a two-component liquid silicone rubber, the lack of platinum catalyst this type of two-component liquid silica gel is unable to form, of course, the catalyst is not only platinum type, and is organic tin. There are differences in the properties of silica gel products vulcanized by the two catalysts. In the operation of liquid silicone rubber to add platinum catalyst according to the proportion of ratio, so if the proportion is not correct, add more or less will lead to what happens?

Liquid silicone rubber needs to add platinum catalyst for operation, and the general operation ratio, that is, the ratio of AB component is 1:1. Need to pay attention to its operation ratio is weight ratio, or volume ratio, some old master usually according to their own feelings for visual ratio, do not use external tools for operation, such as electronic scales, measuring cups. Usually in this case, the operation ratio is not accurate, and the platinum catalyst component is increased or decreased. Adding too much platinum catalyst to liquid silicone rubber will lead to accelerated vulcanization of silica gel. It is possible that the operation is not completed, and the liquid silicone rubber will enter the vulcanization stage, resulting in the final inability to operate.

In addition to affecting the vulcanization speed of liquid silicone rubber, it will also lead to the deterioration of the performance of the silicone rubber mold and products after vulcanization molding, such as the tension is poor, a tear is broken, the service life is short, and it may also lead to the occurrence of oil on the surface of the silicone product. Therefore, when operating liquid silicone rubber, it is necessary to use the corresponding operation tool to proportion according to the operation instructions, to avoid the error of proportion, which leads to a series of problems.

If you want to accelerate the vulcanization of liquid silicone rubber, you can use heating to accelerate the speed, and try to avoid adding excessive platinum catalyst to accelerate the speed. Liquid silicone rubber added platinum catalyst series bad would happen, excessive organic tin type liquid silicone rubber will also appear similar situation, so no matter what type liquid silicone rubber to strictly follow the operation ratio of operation instructions, such as unclear ratio of concrete operation can be directly consulting liquid silicone rubber factory, avoid error, lead to bad happened.
