How to use 502 Super Glue; Eight bonding characteristics of 502 Super Glue

I believe everyone knows 502 super glue, because in daily life, this kind of super glue is still commonly used, and we often use it to bond some things. 502 is a fast and convenient super adhesive, and it is also convenient to buy in the market. Most supermarkets or canteens will sell it, so 502 is a popular product, and it is a kind of super glue that is very popular and commonly used in life. The following small series will tell you the characteristics of this glue.

Introduction of 502 Super Glue

502 glue, if exposed to air, comes into contact with a trace of water vapor, which is characterized by rapid polymerization, curing and adhesion, so it is called instant adhesion.

The chemical molecular formula of adhesive 502 is CH2 = C(CN)- Chief Operating Officer -C2H5, colorless and transparent, low viscosity, flammable liquid, one component, solvent-free, slightly irritating, volatile, volatile and weakly tearing.

502 glue has certain toxicity, but the toxicity will be reduced after curing, but 502 glue is a cyano compound after all, and it will produce toxic substances after decomposition. When it encounters moist moisture, it is catalyzed, rapidly polymerized, solidified and adhered. Under the catalysis of trace water in the air, the polyaddition reaction takes place, which quickly solidifies and sticks the adherend firmly.

Glue 502 is used to bond porous and absorbent materials, as well as 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. 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.

Similar products are 40 1, 4 15 and so on. The effect is similar to that of 502, and the price is relatively expensive on the market. There is also low-priced green red glue, which is also a kind of AB glue, and the price is relatively cheap.

How to use 502 super glue

1. Before use, clean the surface of the adherend to remove dust, oil stain and rust. When bonding metals, it is best to grind them first. When bonding plastics such as PE and PP, surface activation should be carried out first.

2. Open the front cover of the glue bottle, gently buckle the tip with your fingers without leaving any residual liquid, and then cut out the hole with scissors.

3. Drop a small drop of this glue on the surface of the adherend, and stick it immediately until it becomes hard. Of course, the bonding area should not be too large.

4. Wipe the glue bottle clean after use, cover it tightly, and store it in a cool and dry place or in cold storage.

Specific safety matters of 502 super glue

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.

1. The steam of this adhesive will irritate eyes, so be careful when using it.

2. Avoid contact with skin and eyes. If there is an accident, immediately rinse with plenty of water and send it to the hospital. When cleaning eyes, you can use dilute sodium bicarbonate solution.

3. When touching your hands, you can wash your hands with soapy water, washing liquid or pumice.

Eight bonding characteristics of 502 super adhesive

1, single ingredient: solvent-free, easy to use.

2, instant connection: using a small amount of water vapor in the atmosphere, you can connect in a very short time.

3, room temperature hardening: can be used at room temperature, without heating.

4, transparent and colorless: good effect, no deterioration.

5. High viscosity: suitable for adhering porous and absorbent materials.

6, 502 super glue, colorless and transparent, liquid with good fluidity, volatile, polymerized and solidified in water.

7. The product has the advantages of single component, fast curing speed, convenient use, strong adhesion and wide range of bonding materials.

8, 502 glue is a kind of one-component instant curing glue, because of its fast bonding speed and firm bonding.

The characteristics and effects of 502 super glue are well known to everyone. It's easy to use and it's a good adhesive. But when you use this 502 super glue, you will also encounter some problems, that is, you accidentally stick it wrong, or the super glue sticks to other things or hands, which is also very laborious. But don't worry about this. There are many ways to remove super glue now. If you are interested, continue to pay attention to us and learn!
