1 Polyaddition Silicone Rubber Catalysis

Catalysis of polyaddition silicone rubber is a fundamental process for creating resin products. This type of silicone rubber is known for its ability to cure rapidly thanks to the addition of a catalyst.

2 Inhibitory Substances in Catalysis

There are several substances that can inhibit the catalysis process of polyaddition silicone rubber. Among the most common are heavy metals such as tin, copper, and zinc. These substances can be present in trace amounts in other materials and contaminate the resin surface, compromising the catalysis.

3 Action Mechanism of Inhibitory Substances

Inhibitory substances act by binding to the catalyst present in the silicone rubber, preventing its proper functioning. This binding can cause an alteration in the polyaddition reaction, slowing it down or even completely blocking it.

4 Strategies to Prevent Catalysis Inhibition

To prevent the inhibition of polyaddition silicone rubber catalysis, it is essential to use high-quality materials and carefully control the cleanliness of tools and work surfaces. Additionally, specific catalysts can be used that offer greater resistance to inhibitory substances. In summary, to avoid issues related to catalysis inhibition of polyaddition silicone rubber, it is advisable to rely on quality materials like those available on RESINPRO. On the website, you can find all the necessary products to ensure effective and smooth catalysis.
