HandymanHow to use PVC glue
The main component of PVC glue is polyvinyl chloride resin, which is a new type of single-component fully transparent solution glue. It can be used for mutual or cross-bonding of plastics and plastics, plastics and metals, and plastics and non-metals. This encyclopedia mainly introduces PVC glue from several aspects, such as the characteristics of PVC glue, the use of PVC glue, the precautions for using PVC glue, and how to wash off PVC glue.
1. Characteristics of PVC glue
First, it has the advantages of room temperature curing, high bonding strength, high elasticity, fast positioning, soft film, non-toxic solidified material, and easy operation.
Second, it has excellent water and heat resistance, acid and alkali resistance, corrosion resistance, oil resistance, and no whitening.
Third, it can be widely used for mutual and cross-bonding of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), ABS, PS, PMMA, sponge, film, nylon, metal, non-metal and other materials.
2、How to use PVC glue
First, clean the oil, dust and other dirt on the surface of the adherends and keep them clean and dry.
Second, directly apply the PVC glue evenly on the surfaces of the two adherends, wait for 5-10 minutes, until the film is slightly non-sticky and has a dry touch, align the two adherends for bonding, and apply a little pressure to make the bonding surface more closely fitted. Leave it for about 1-2 hours, it will reach a certain strength in 4-6 hours, and reach the highest strength in 24 hours.
Third, if you need to improve the strength and temperature resistance of the bond, you can pre-coat the surface of the material with a treatment agent, and add 5%-8% of the curing agent to the PVC glue and stir it thoroughly. This can significantly improve the bonding strength and temperature resistance. If it is heat-activated at a temperature of 60-75°C for 4-7 minutes before bonding, the effect will be better. Note that the glue with the curing agent must be used up within 12 hours.
3、Precautions for using PVC glue
First, PVC glue is flammable. When using it, pay attention to ventilation and avoid contact with open flames.
Second, the container should be tightly covered after use to prevent the colloid from solidifying.
Third, PVC glue should be placed in a cool place and sealed for storage. The general storage period is 1 year. When using the remaining stored glue, use a small amount at the end to test whether it is qualified.
Fourth, do not move the bonding surface easily to prevent air from entering and affecting its strength.
Fifth, PVC glue should be placed out of reach of children as much as possible to avoid accidental ingestion.
4. How to wash off PVC glue
First, how to wash off PVC glue on clothes
1. You can pour a little insulating oil on the clothes, which can make the PVC glue soften quickly and can be washed.
2. PVC glue is a kind of resin glue. It can be washed off with an organic solvent that can dissolve the resin, such as acetone. However, acetone is toxic, so be careful when using it.
3. If only a small area of PVC glue is stuck on the clothes, you can soak it in hot water. If a large area is stuck with PVC glue, it is recommended to apply acetone, which can be removed in about 5-10 minutes.
Second, how to wash off PVC glue on your hands
The best way is to dilute it with rosin, and then wipe it slowly, but the smell of rosin is unpleasant, so you can use soap or hand sanitizer to remove the smell.
