Features:

825S is a high-performance chlorinated polypropylene resin, which is made of isotactic high-grade PP chlorinated and then grafted with functional groups. After being melted into a liquid state, it has excellent adhesion to various types of plastic materials, and is compatible with large Some common solvent-based resins have good affinity and are widely used in one-component advanced coating systems.

After the 825S resin is dissolved into a liquid, it has good resistance to low temperature freezing, and the solution does not freeze at (-5°C to 0°C).

主要用途：

1. Plastic composite binder.

2. Gravure plastic composite ink binder.

3. PP, PET, ABS, PVC use material binder.

4. Heat resistant ink binder.

5. Anti-corrosion coating binder.
