Application areas 

Powder coating 

Product features and benefits 

The additive improves the surface smoothness and scratch resistance of powder coatings, and improves the stain resistance of powder coatings. 

Recommended dosage 

0.5-2 % additive dosage (in supply form) based on total formulation. 

The above recommended addition amount is for reference only, and the suitable addition amount needs to be determined by a series of tests. 

Incorporation method and processing guidance 

The additive should be mixed and stirred with resin, curing agent, pigment and other additives at high speed, and then all extruded and discharged.

Coatings industry 

Product features and benefits 

The additive adds a smooth surface of solventborne coatings and improves scratch resistance, metal resistance and dark heel marks. It also increases the hydrophobic properties of the coating. 

Recommended use 

Architectural coatings 

Coatings for wood and furniture

Can listen to the coating 

Coil coatings

Recommended dosage 

0.3-2 % additive dosage (in supply form) is based on total formulation. 

The above recommended addition amount is for reference only, and the suitable addition amount needs to be determined by a series of tests. 

Add method and processing guidance 

The additive is best added to the coating at a moderate shear rate at the end of the production process.
