Potassium Methyl Siliconate Manufacturer introduces what is hydrogen silicone crosslinking development:

The traditional preparation method of silicone resin and room temperature vulcanized silicone rubber is to use the condensation reaction of silanol groups and alkoxy groups, and the development of the addition reaction of vinyl groups and hydrogen has brought great technological progress. The addition reaction can control the curing speed, and no by-products are formed, so the electrical properties and heat resistance of the products are improved. In terms of the condensation reaction, various crosslinking agents for single-component room temperature vulcanized silicone rubber have also been developed. On the basis of the original acetic acid type, ketoxime type and alcohol type crosslinking agents, oxygen type, and amide-type crosslinking agents which can make the silicone rubber have low modulus and large elongation were developed. Furthermore, an acetone-type crosslinking agent with low toxicity, fast curing, and no decomposition at high temperature has been developed.

In recent years, the liquid silicone rubber developed by hydrosilicone cross-linking has attracted people's attention. The rubber compound has single-component and two-component. At present, the most used is the two-component. The tensile strength of liquid silicone rubber can reach 8 ~ 9M Pa, it has high production efficiency, each machine can produce 106 parts in one year, and the production of small parts can reduce the cost by 1/4.
