Can 502 glue stick to plastic, can 502 glue stick to plastic

502 glue can be used to stick plastics, and is widely used in steel, non-ferrous metals, non-metallic ceramics, glass, wood and flexible materials such as plastic products, leather shoes, soft and hard plastics, etc.

We often use 502 glue in life, its functionality and practicability are very strong, so can 502 glue stick to damaged plastics? Let's talk about it.

01 502 glue is the common name of a large class of fast adhesives with a side chain of ethyl cyanoacrylate, and ethyl acrylate is an important chemical adhesive, a wide range of applications, ethyl cyanoacrylate is generally liquid at room temperature, the main difference between different varieties of 502 glue is in the size of the side chain, and different additives will also bring certain differences to the properties of the glue itself.

02 Different from the solvent glue we generally use when making models, 502 glue is a kind of resin glue, which does not have a dissolution effect with the host, but relies on the force between the ethyl acrylate formed during the curing process and the host to form a firm adhesion effect.

03 502 The curing process of glue requires heat exchange, and the better the heat exchange conditions, the faster the curing, which is why bonding metals with good heat conductivity is faster than bonding plastics, and a thin layer of glue also dries much faster than a large drop of glue.

04 502 glue can stick to plastics, if exposed to the trace amount of water vapor in the air, that is, it is catalyzed and quickly polymerized and solidified and adhered to the characteristics, so it is called instant adhesive. It is widely used in steel, non-ferrous metals, non-metallic ceramics, glass, wood and flexible materials such as rubber products, leather shoes, soft and hard plastics, etc., but for polyethylene, polypropylene, PTFE and other difficult-to-stick materials, its surface needs to be specially treated before it can be bonded.

Sticky plastic with 818 glue can be sticky.

502 Jiaosong silver water can not stick to plastic.

502 glue can not be used to stick plastic, plastic is a polyethylene material, not an active molecule, in the process of pasting, it is not easy to produce heat exchange, so it can not play the bonding role of exchange, resulting in the later use of cherry blossoms, there is a situation of falling off.

The correct way to use 502 glue:

1. In the process of using 502 glue, it is necessary to clean up the dust and stains on the surface of the construction surface to ensure the paste effect in the later stage. Under normal circumstances, when bonding metal, it is necessary to carry out grinding work first, and when PE and PP plastic are bonded, it is necessary to activate the surface.

2. When using 502 glue, you need to open the lid of the glue, and use your fingers to buckle the position of the tip so that there will be no residual liquid, and then use scissors to cut out the holes. Then, a small amount of glue drops are placed on the construction surface and then pasted until it is hardened. Note that the bonding area should not be too large.

3. When the 502 glue is used up, the glue bottle needs to be wiped clean, then covered with a lid and placed in a cool, dry area for preservation. Note that if there are children in the family, it must be raised to avoid accidental ingestion by children and unnecessary trouble. <>

502 can stick plastics and plastics. This product is widely used in steel, non-ferrous metals, non-metallic ceramics, glass, wood and flexible materials, such as rubber products, leather shoes, soft and hard plastics, etc., but for polyethylene, polypropylene, PTFE and other difficult-to-stick materials, the surface needs to be specially treated before bonding.

502 This glue will not dissolve with the article during use, and it is cohesive to achieve the effect of sticking through curing. 502 glue needs heat exchange in the curing process, (those who have been glued by 502 glue may know that the glue dripping on the hand will have a hot feeling, which is the obvious external manifestation of heat exchange), the faster the curing, the faster the sticking.

No. 502 is an instantaneous super strong adhesive. It does not have a dissolution effect with the host, but relies on the force between the ethyl acrylate formed during the curing process and the host to form a strong adhesion effect.

The curing process of 502 glue requires heat exchange, and the better the heat exchange conditions, the faster the curing, which is why bonding metals with good heat conductivity is faster than bonding plastics, and a thin layer of glue also dries much faster than a large drop of glue.

502 glue can stick to ordinary plastics, but difficult to stick plastics can't, so use HY-302AB glue for difficult to stick plastics.

HY-302ABPP glue is mainly used for adhesives of various plastic products, PP PE POM, NYLON and other difficult-to-stick plastic materials, which require high requirements for rapid adhesion between different materials and super adhesion.

502 quick-drying glue can stick some ordinary plastic materials, and the surface is more difficult to stick with special glue.
