AB announced the preparation of two-component glue

AB is a two-component adhesive (A-component)-based polymer and a filler material made of the distribution, and contains a crosslinking agent; (B-component curing agent) as a catalyst and a crosslinking agent formulated as a main component. That binder contains a crosslinking agent, a vulcanizing agent, the main component of the catalyst. When using, AB uniformly mixing the components by a certain percentage, then allowed to stand at room temperature vulcanized elastomer. 　　Contract type AB component RTV silicone rubber has the following features: 　　1 heat resistance, cold resistance, weather resistance, durability and chemical resistance; 　　2 Variety and quantity of  base and curing agent can be used to control the time; 　　3 Variety and volume  may base and curing agent can be used to control the time; 　　4 Use of deep curing agent, can be cured simultaneously with the internal surface; 　　5 Most species in contact with the substrate  without adhesion, and have a good mold release; when bonding requirements, the need to primer treatment; 　　6 There mobility of low viscosity to high viscosity, non-current varieties for selection.     　　AB-component silicone preparation 　　AB component of the curing process in the presence of a catalyst, the molecular basis of the carboxyl group with the crosslinking agent in the polymer molecular chain end a hydrolyzable group may be a condensation crosslinking reaction. A component-based polymers, fillers and other ingredients formulated the base material, the design should be based on the use of prescription and preparation process requirements, with pre-vulcanized and vulcanized to take performance to meet the requirements. Low viscosity base material, in a planetary mixer, and mixing the base polymer and the silica prepared directly for the preparation of good fluidity, the amount of reinforcing filler of the base material more than can be taken to be formulated in high kneader masterbatch filler content, the dilution method, anti-flowing nature of the base material, and can be formulated in connotation or planetary mixer. 　　B-component curing agent is generally from TEOS or n-propyl silicate, and their partial hydrolysis and condensation thereof as the crosslinking agent, a dialkyl tin dicarboxylate or the like as a catalyst, according to a certain mixing ratio, and then with other additives (curing deep catalytic additive, the vulcanization rate regulating additives, corrosion inhibitors, diluents, fillers, etc.) were prepared. Add the appropriate amount of curing agent organic acids, have mixed base may extend life. 　　Shenzhen Hongye Jie Silicone factory is specialized in silicone products and their production, research and development, and sales of Science and Technology Corporation.
