What is Heptamethyl trisiloxane?


With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Heptamethyl trisiloxane which has developed particularly rapidly in recent years. Do you know about Heptamethyl trisiloxane?

The official answer:Polymethyl hydrosiloxane is a kind of silicone oil used in biology and chemistry. Under the action of metal salts catalyst, low temperature can be cross-linked to form a film, in a variety of material surface shape Chemicalbook into a waterproof film, can be used as a waterproof agent for various materials such as fabrics, glass, ceramics, paper, leather, metal, cement, marble; especially the waterproof of fabrics.

What’s the application of Heptamethyl trisiloxane?

Polymethyl hydrosiloxane is a kind of silicone oil used in biology and chemistry. Under the action of metal salt catalyst, it can cross-link to form a film at low temperature and form a waterproof film on the surface of various substances, which can be used as a waterproofing agent for various materials such as fabric, glass, ceramics, paper, leather, metal, cement, marble, etc.; especially the waterproofing of fabric. Methyl hydrogen-containing silicone oil emulsion and methyl hydroxyl silicone oil emulsion shared, can waterproof and keep the breathability of the fabric and can improve the tear strength, abrasion strength, and stain resistance of the fabric, improving the feel of the fabric and sewing performance. In addition, it is used as an anti-adhesive isolating agent and cross-linking agent for paper.
