Is 52 universal glue?
Yes, 52 is a strong glue. Because of its strong adhesion, it is suitable for almost all surfaces. It is also called universal glue.
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, if exposed and exposed to trace water vapor in the air, is characterized by rapid polymerization, solidification and adhesion, so it is called instant adhesive. The chemical molecular formula of 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, but 52 glue is a cyano compound after all, and it will 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.
