52 adhesive is a one-component instant curing adhesive which is mainly composed of α-cyanoacrylate, and added with tackifier, stabilizer, toughening agent and polymerization inhibitor, etc. through advanced production technology. Can stick to many things.
52 glue is called instant adhesive, because it is exposed and exposed to trace water vapor in the air, and it is quickly polymerized and solidified by catalysis.
the chemical molecular formula of p>52 glue is CH2=C(CN)-COO-C2H5, which is colorless, transparent, low viscosity, flammable liquid, single component, solvent-free, slightly irritating, volatile, and volatile with weak tear.
52 glue has certain toxicity, but the toxicity will be reduced after curing. However, 52 glue is a cyano compound after all, and it will also produce toxic substances after decomposition. When it meets wet moisture, it is catalyzed and quickly solidified and adhered. Non-toxic after curing. The polyaddition reaction takes place under the catalysis of trace water in the air, which quickly solidifies and sticks the adherend firmly.
52 glue is used for bonding porous and absorbent materials, and for bonding steel, nonferrous metals, rubber, leather, plastics, ceramics, wood, nonferrous metals, nonmetallic ceramics, glass and flexible materials such as rubber products, leather shoes, soft and hard plastics, etc. However, the surfaces of difficult-to-stick materials such as polyethylene, polypropylene and polytetrafluoroethylene need special treatment before bonding. Widely used in electrical appliances, instruments, machinery, electronics, optical instruments, medical care, light industry and civil industries.
