Who knows how toxic 502 glue is and what will be the consequences of long-term exposure?

Ordinary glue, its composition is basically water, and some polyvinyl alcohol, white latex, sodium stearate, talcum powder, urea, ethylene glycol, sucrose, essence and so on. They are all added and harmless to human body (if eaten). If used as eye drops, the consequences are estimated to be more serious. 1, product name: product name: a- cyanoacrylate quick sol, 502 glue 2, English name: a- cyanoacrylate adhesive super glue 3, main ingredient: N | CH2=C-COOC2H5 4, physical and chemical properties: colorless and transparent, low viscosity, nonflammable liquid, one component, solvent-free. When it encounters moist moisture, it is catalyzed and quickly solidified and adhered. Non-toxic after curing. 5. Features and uses: If this product comes into contact with water vapor in the air, it will quickly polymerize and solidify through catalysis, so it is called quick-drying adhesive. This product is widely used for bonding flexible materials such as steel, nonferrous metals, nonmetallic ceramics, glass, wood and rubber products, leather shoes, soft and hard plastics. However, the surfaces of difficult-to-bond materials such as polyethylene, polypropylene and polytetrafluoroethylene need special treatment before bonding. Usage: When using, first clean the bonding surface to remove oil stains, then apply proper amount of glue (8 ~ 10 cm2 per drop of glue) to the bonding surface, and apply appropriate force and pressure to the bonding surface, and then stick it firmly later. The adhesive can be delivered when the maximum adhesive strength is reached in 24 hours. 7. Safety precautions: This product adheres quickly to prevent skin and clothes from sticking during operation. This product has weak tearing property, so be careful not to splash it into eyes, and pay attention to ventilation when using it.
