RTV SILICONE SEALANT ADHESIVE (ACID) factory introduces the composition of silicone sealant
RTV SILICONE SEALANT ADHESIVE (ACID) factory introduces the content of silicone sealants to you.
Silicone sealant refers to the sealant produced with linear polysiloxane as the main raw material, also called silicone sealant, which is a kind of silicone rubber. The polymer main chain of silicone sealant is mainly composed of silicon-oxygen-silicon bonds, and other organic sealants whose polymer main chain is mainly composed of carbon-carbon bonds (such as: polyurethane sealant, acrylic sealant, polysulfide sealant, etc.) Compared with sealants, etc.), the most notable features are excellent high and low temperature resistance and weather resistance.
According to the types of small molecules released during curing, architectural silicone sealants can be mainly divided into deacetic acid type, deketoxime type, dealcoholized type, and deamidated type.
Basic knowledge of silicone sealants
Room temperature vulcanized silicone rubber (RTV) is a new type of silicone elastomer that came out in the 1960s. The most notable feature of this rubber is that it can be cured on the spot without heating or pressing at room temperature, and it is extremely convenient to use. Therefore, as soon as it came out, it quickly became an important part of the entire silicone product.
RTV SILICONE SEALANT ADHESIVE (ACID) factory tells you: 'Now room temperature vulcanized silicone rubber has been widely used as adhesives, sealants, protective coatings, potting and molding materials, and it has its uses in all walks of life. RTV silicone rubber is known as liquid silicone rubber because of its low molecular weight. Its physical form is usually flowable fluid or viscous paste, and its viscosity is between 100 and 1,000,000 centistokes.
MODIFIED ACRYLIC AB ADHESIVE (BOXES) uses methyl methacrylate as the main raw material, with tougheners, reinforcing agents, stabilizers, initiators, polymerization inhibitors, etc., two components synthesized through advanced technology (A, B) Reactive structural adhesive.
