Silicone rubber waterproof coatings are emulsion-type waterproof coatings prepared by mixing silicone rubber emulsion and other high molecular polymer emulsions as the main raw material, mixing appropriate chemical additives and fillers, etc., uniformly mixing. The coating has good permeability, film-forming properties, water resistance, elasticity, adhesion, high and low temperature resistance, etc., and can be used for construction operations on dry or damp bases without clear water.Silicone w ...

Release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when it comes in contact with the chemical components of different resins (especially styrene and amines). The release agent also has heat resistance and stress properties, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the processed part, and does not interfere with painting or other secondary ...

The main ingredients of food-grade defoamers include calcium carbonate\sorbitan fatty acid ester\silicone oil\food preservatives, etc. Of course, there will be a certain amount of short-chain fatty acid defoamers in general defoamers. There are many types of antifoaming agents. Alkyl, polyether, silicon and ether grafts, containing amines, imines and amides, have faster defoaming speed, longer foam suppression time, wider range of applicable media, and even harsh media environments such as high ...

Foamed silica gel is also called addition molding silica gel. It is composed of silica gel and curing agent at a ratio of 1:1. After being vulcanized, it becomes a soft elastic material. It is an environmentally friendly material, the products produced are non-toxic, tasteless, safe and sanitary. Flexible silicone rubber products such as human body, insoles, shoulder pads, patches, non-slip pads, etc. can be made. Tear strength: 55Kn/m; ductility: 100%; temperature range: -40-220℃; fire rating: ...

1 Industry status of methyl high-hydrogen silicone oilMethyl high-hydrogen silicone oil is often referred to as high-hydrogen silicone oil. It is a very important silicone oil product that is very popular at home and abroad. The siloxane main chain in the high-hydrogen silicone oil product contains highly active silicon-hydrogen bonds, which can react with many active groups, and the surface energy of methylsiloxane chain links is low, so its synthetic materials have good properties. Water resis ...

The oil-based glue defoamer is made of ether, fatty alcohol and multiple active additives through a special process. It is easy to disperse in water-based system, has strong self-emulsification, good defoaming, long-lasting foam suppression, and has special effects on water-soluble polymers and medium and low viscosity systems. It is especially suitable for latex-type water such as styrene-acrylic, ethylene-propylene, pure acrylic, vinyl acetate emulsion, and carboxylated styrene butadiene. It h ...

Background technique:The existing silicone surfactants used to prepare polyurethane rigid foams all use hydrogen-containing silicone oil and allyl alcohol as the initiator, and the allyl polyether reaction of the alkylation reaction of ethylene oxide and propylene oxide The allyl polyether, which is usually used to prepare the silicone surfactant of polyurethane rigid foam, is an unblocked polyether.Although the acetyl-terminated allyl polyether has a high end-capping rate, some products can rea ...

High resilience liquid silica gel is a kind of silica gel with better resilience. Because liquid silica gel is safe and environmentally friendly, it can fully meet the requirements of food grade. It can be used for baby products, such as baby pacifiers. High resilience liquid silica gel has good flow properties and fast vulcanization., Fast molding speed, yellowing resistance, heat aging resistance, excellent tear strength and other advantages, and easy to use, so it has a wide range of uses, su ...

Silicone resin is a highly cross-linked polyorganosiloxane with a network structure, usually methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylbenzene Various mixtures of dichlorosilanes, in the presence of organic solvents such as toluene, are hydrolyzed at lower temperatures to obtain acid hydrolysates. The initial product of the hydrolysis is a mixture of cyclic, linear and cross-linked polymers, usually containing a considerable number of h ...
