502 glue component is the α-cyano-acrylic acid ethyl ester.
The main ingredients: N
CH2 = C-COOC2H5
Physical and chemical properties: colorless, transparent, low viscosity, non-flammable liquid, single component, solvent-free, slightly stimulate the taste, volatile, volatile gas with weak tear. Case of wet water gas is catalyzed, rapidly co-curing adhesive. After curing non-toxic.
Peculiarity: This product exposed to trace amounts of water vapor in the air access solution, that is, catalytic rapid polymerization curing adhesive characteristics, it is known as instant adhesives. This product is widely used in iron and steel, non-ferrous metals, non-metallic ceramic, glass, wood and flexible materials such as rubber products, shoes, soft, hard plastic itself or inter-adhesive, polyethylene, polypropylene, PTFE difficult sticky materials such as ethylene, its surface and subject to special treatment before being bonded.
502 glue role: The main ingredient with one sidechain cyanoacrylate categories rapid adhesives commonly known, and the ethyl acrylate is an important chemical adhesives, a very wide range of applications, cyanoacrylate B generally exhibit liquid ester at room temperature, 502 different varieties of glue main difference in the side chain size, different additives can bring some difference to the traits of the glue itself. Unlike general model solvent glue (for example: Tamiya glue), 502 glue is a resin glue itself does not dissolve effect between the host, but on the formation of ethyl acrylate in the curing process with the force between the host to form a solid stick and effects. 502 glue curing procedure requires heat exchange, the better the heat exchange conditions, the faster the curing, this is why the adhesive of good thermal conductivity metal faster than the adhesive plastic and a thin layer of glue than a large drops of glue to dry quickly many
Usage: when used to clean the rubber surface, in addition to net oil, then combined with surface coating, the amount of adhesive to moderate (each drop of glue can be coated 8 ~ 10cm2) anastomosis plastic junction and appropriate force pressure, slightly be a moment to cement. 24 hours maximum bonding strength adhesive material before delivery.
Security matters: the adhesive quickly and prevent the operation in the skin, clothing adhesion of this product with weak tear gas, beware of splash in the eyes, attention to ventilation.
How to wash away 502 plastic:
1, you can use a hot towel wet stick 502. Ten minutes after the curing of the 502 will become soft, can be cleared. There can be in the 502 place drop on a drop of 502, 502 cured become soft, this can be removed with a towel.
2,Insulating oil, pour point transformer insulating oil on the table, 502 glue quickly softened quickly rub off.
3,502 glue is an instant adhesive, as long as the organic solvent can dissolve, such as acetone. Acetone solution is washable. Inhalation of acetone toxic, pay attention to use part of viscose can be stuffed into the bottle. Is said to put in the fridge freezer, the glue will fall off, you can first try.
4, a small area of glue 502 glue, as long soak with hot water, if a large area stained with 502 glue, coated with acetone, about 5 to 10 minutes and so on can be removed.
