Silicone pressure-sensitive adhesive is a special adhesive composed of silicone resin (commonly used MQ silicone resin), silicone rubber, catalyst, crosslinking agent and other additives. Silicone pressure-sensitive adhesives mainly include solvent type, high solid content type, solvent-free type, emulsion type, radiation curing type, resin modification type, biodegradable type, functional type and other systems.Since the solvent type contains a large amount of volatile organic compounds, during ...

Silicone glue is a kind of ointment, once exposed to moisture in the air, it will solidify into a tough rubber-like solid material. It is mainly divided into de-acetic acid type, de-alcohol type, de-ammonia type, and de-C type. Silicone glue is commonly called glass glue because it is often used for bonding and sealing of glass. One-component silicone glass glue is a kind of ointment, once it comes into contact with moisture in the air, it will solidify into a tough rubber-like solid material.Si ...

Commonly used foam agents and foam stabilizers are theseThey make the pores fine and uniform. When the system is in the low viscosity stage, it stabilizes the pore wall/the pores can grow to a thickness suitable for the opening, creating conditions for the final opening. The type of foam is different, and the type of stabilizer used is also; at the same time, its main function is to nucleate and emulsify each component in the formula. The compatibility of the various components in the foam formu ...

The leveling principle of silicone leveling agent: surface tension is the main driving force for the leveling of the coating film, but the poor surface tension is the main source of the surface defects of the coating film. Improve the surface tension of the coating film to achieve a balance of surface tension, which is very beneficial to the flow and leveling of the coating film, but it cannot be done. Therefore, people have to reduce the surface tension of the coating film to eliminate the diff ...

Application and selection of defoamers for water-based coatings. The water-based paint defoamer is a composite product of organic polyether ester, mineral oil, and alcohol. It will not produce surface defects or affect the film-forming properties, and has a special effect on the water-based paint system.product manualUsing water instead of organic thorns to prepare paint is safe, inexpensive and hygienic. After the emergence of synthetic resins, water-based coatings developed rapidly. Water-base ...

Solvent-free impregnating varnish is widely used in the VPI insulation treatment of motor coils in high-end fields such as high-voltage motors, high-speed traction motors, and spacecraft engines. Silicone materials have the advantages of high temperature resistance and corona resistance, and are more suitable for insulation in the above fields deal with. With the continuous development of my country's high-speed railway, subway, light rail, and magnetic levitation technology, insulating material ...

Silicone resin materials are a kind of polymer materials with silicon-oxygen bonds as the main chain structure and organic groups as side groups. It has excellent thermal oxidation stability and insulation properties. Its service temperature can reach 200℃～220℃, and its heat resistance can even reach 250℃～300℃ after modification. At the same time, its molecular structure is close to that of silicate. It is a semi-inorganic polymer, so it has excellent insulating properties, with a dielectr ...

A silicone impregnating resin was synthesized from methylphenyl silane monomer and special silane monomer to prepare organosiloxane prepolymer. The impregnating resin does not contain any organic solvent and is a low-viscosity fluid liquid at room temperature. The structure and physical properties of the impregnated resin were characterized by infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy and gel chromatography. The results show that the polyorganosiloxane conta ...
