There are several names for Two-component glue. In Taiwan, we call it as AB glue, two glue, two-component glue, mixed glue, 2K or two-component, and so on. According to different characteristics, two-component glue can be categorized into three types, they are:
1. Polyurethane: generally called PU. Main agent “Poly” needs to be mixed with catalyst/hardener; also known and used as “Iso,” it is able to resist acid and alkali and prevent the corrosion of organic solvents. It can be widely used in the industrial fields, such as bonding, coating, foaming and gasket.
2. Epoxy: by mixing the agent A and B, a chemical curing reaction is produced. The material has excellent electrical properties, water resistance, wear resistance and high level of adhesion. It is mainly used for lamination, filling, sealing, coating, or structural reinforcement.
3. Silicone: the material has strong thermal stability (which can be maintained between 100-250°C), water tightness and antioxidant capacity. After mixing, the material is moisture proof and it also has good elasticity. Its industrial usage are filling, sealing, gasket, and so on.
In addition to the three types raw materials above, our two-component glue equipment is also suitable for Acrylic, thermal grease, UV glue, liquid silicone rubber (LSR), and so on.
On the whole, “two-component glue” means the mixing of a certain proportion of agent A/ main agent with a certain proportion of agent B/hardener/catalyst, and achieves its physical properties after curing. In contrast, “single fluid” means the raw material can be used alone without mixing.
