三、特性
Application of low viscosity, solid and fast, wide, short term, cheap and practical.
四、用途
Mainly used in metal, rubber, leather, plastics, glass, wood, paper, ceramics, jade, assembly line production.
Main ingredients: N
CH2=C(CN)-COO-C2H5
Properties: colorless, transparent, low viscosity, non flammable liquid, single component, solvent-free, slightly pungent, volatile, volatile weak tear gas. Wet water was catalyzed rapid curing adhesive. After curing drug.
Features
1, a single ingredient: solvent-free and easy to use.
Moments 2, then: the use of trace amounts of water vapor in the atmosphere, then in a very short time.
3, cold hardening at room temperature without heating can be used.
4, transparent colorless: good results do not deteriorate.
5, high viscosity: suitable for porous and absorbent materials
502 glue using methods and points for attention
Using method
1, first clean surface, remove surface dirt, grease, rust and so on, when the metal, the best PACKING, such as PE, PP and PTEE plastics, surface activation first.
2, open the front cover, and tapped her fingers on the tip part, so there is no residual fluid, then the scissors to cut out the hole.
3, was followed by dropping a small drop of glue, instantly and keep up to harden, then size should not be too large, then the layer thickness should not exceed 0.2mm.
4, after use, wipe the container and lid and store in a cool, dry place or refrigerated.
Matters needing attention
1, glue vapors Gill mucous membranes and eyes.
2, avoid contact with skin and eyes, if by accident, immediately wash with plenty of water and taken to hospital, when cleaning the eyes, use a dilute solution of sodium bicarbonate.
3, touching hands, SOAP, wash water, washing-up liquid and a pumice stone. Or soon will be condensed in the hand, to recede in a few days.
Storage: 20 ℃ 3-12 months.
Structural formula: CH2=C(CN)-COO-C2H5
Principle: in addition polymerization catalyzed by trace water in air, fast-curing and stick the sticks in prison.
502 convenience at the same time, sometimes accidentally stick to stuff that you don't want to paste, and removal methods are:
1, water droplets on the glue stains with bananas, but used an old toothbrush and constantly stir the brush, glue traces soft off, then rinse with clear water, repeatedly brushing, brushing the net so far. In clothing with traces of glue on the back pad of absorbent cloth, then rub white vinegar on the traces of glue and finally wipe with cotton dipped in water
2, with the insulating oil, pour transformer insulating oil at table, 502 glue will soon become soft and can begin to rub out.
3, 502 glue is a resinous gum, organic solvents dissolved resin for as long as you can, such asacetone. But inhaling acetone poisonous, using methods, you can partially stuffed into a bottle of glue. Is said to have frozen in the fridge, glue will fall off, you can try it.
4, 502 glue glued to a small area, soak in hot water as long as you can, if large areas coated with 502 glue, apply acetone, approximately 5-10 minutes may drop.
5, recommended, such as acetone, petrol, oil, poured the insulating oil in transformers in hand, 502 glue quickly softens, it is easy to rub out.
6, closed heating can be explosive. (Try not to use this method of risk).
7, if unfortunately stuck to the skin, nail enamel Remover (water) or resurrection of the towel to quickly dissolve the glue on your skin. 、
