Does 502 glue have formaldehyde?

I believe everyone is familiar with 502 glue. It is widely used in life, because 502 glue has good viscosity, which can be used not only for bonding shoes and clothes, but also for bonding steel, metal, rubber, plastic, ceramics, wood and so on. If you accidentally stick it on your hand, you will even tear off the skin if you want to forcibly separate it. So does 502 glue have formaldehyde as a kind of glue? Let's take a look with Qijia. Com experts.

502 glue has no formaldehyde after curing. Although 502 glue has certain toxicity, it only exists in liquid state. When it is liquid, it is stored in a closed container, and its toxicity will not be emitted. Once exposed to air, 502 glue will be catalyzed by water vapor and instantly solidified and bonded. It is non-toxic after curing, so there is no formaldehyde.

What are the advantages and disadvantages of 502 glue?

Advantages of 1 and 502 glue

502 glue is a single component, which is very convenient to use. It can be quickly bonded in a small amount of water vapor in the air and hardened at room temperature. When in use, heating is not required. The bonding effect of 502 glue is very good, and it will not deteriorate basically without external force. The key is a wide range of bonding materials, such as metal, plastic, ceramics, rubber and so on.

2.502 disadvantages of glue

502 glue also has many shortcomings, basically not resistant to impact and vibration, and its brittleness is relatively large after curing. 502 glue can't be used on PP, PE and other non-polar polymer, so it is difficult to bond. In addition, 502 glue is not resistant to aging, high temperature and water, and it is easy to fail when used in high temperature, humidity and other environments.
