2, features: single component, no heating, instant bonding under contact pressure.

3. Main uses: used in steel and non-ferrous metals; Self-adhesion or mutual adhesion of rubber, leather, plastics, ceramics, glass, wood and other materials.

However, when used in polyethylene, polypropylene and polytetrafluoroethylene products, the surface of the material needs special treatment. Generally, T-type medium and high viscosity series products also have flexibility and excellent water resistance, and the filling gap is 0. 1-0.25mm, which is suitable for bonding porous materials with large surface gap. The fast-curing S-type (commonly known as 3-second glue) is also suitable for bonding difficult-to-stick materials such as plasticized PVC and synthetic foam.
