Application: 1. The function of benzoin is to eliminate the bubbles in the molten powder coating solution, that is, to eliminate the main factors that cause pinhole defects in the coating film.

 

          2. This product is suitable for all types of powder coatings.

 

          3. Dosage: 0.3~0.8% of the total powder. The specific dosage should be determined by experiment.

 

          4, use: can be directly added, mixed with other materials and extruded.

 

          5. The amount of benzoin in the powder coating should be controlled because it will affect the yellowing of the film.
