Scientific name: Polymethylhydrosiloxane CAS No.: 63148-57-2
Colorless and transparent liquid, with weather resistance, good hydrophobic effect and other characteristics, can be cross-linked into a film at low temperature under the catalysis of metal salts, and has moisture-proof, mildew proof, rust proof and air permeability. It can be used as the moisture-proof and waterproof treatment of gypsum, fabric, glass, ceramics, paper, leather, metal, cement, marble and other materials.
It can also be used as anti yellowing agent of high temperature vulcanized silicone rubber, cross-linking agent of addition silicone rubber series products, diluted silicone ink, anti sticking isolating agent and cross-linking agent of paper.

Widely used:
① Waterproof agent (gypsum board, fabric, glass, ceramics, metal, cement, marble, powder, granular and other materials) to make it water repellent and prevent caking
② Used as the finishing of fabrics (cotton, linen, silk, acrylic, polyester, etc.), giving them waterproof and antifouling properties, good hand feel, drapability, anti shrinkage and wrinkle, etc
③ Water repellent treatment of powder to prevent caking (such as powder treatment of dry powder extinguisher, mica, clay, silica and other powders)
④ Anti stick isolating agent and cross-linking agent for paper, waterproof softener for glass fiber
⑤ Anti yellowing agent of high temperature vulcanized silicone rubber
⑥ Crosslinking agent of addition silicone rubber series products
⑦ Thinner for silicone ink
