Application Information

Coatings Industry
Special Features and Benefits

The additive is used as an anti-cratering and leveling additive in all solvent-borne coatings. It increases gloss and gives the coatings a long wave effect. It only causes a minor reduction in surface tension and does not negatively influence the recoatability and intercoat adhesion. BYK-358 N does not cause turbidity in clear coats or haze in pigmented systems. The additive is thermally stable.
Recommended Levels
0.1-1% additive (as supplied) based upon total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.

 

Ambient-curing Plastic Systems
Special Features and Benefits

The additive is used as an anti-cratering and leveling additive in all solvent-borne and solvent-free systems. It only provides a minor reduction of the surface tension and facilitates the acceptance of spray mist and dust. BYK-358 N does not cause turbidity in non-pigmented systems or haze in pigmented systems.
Recommended Use
The additive is recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins.
Recommended Levels
0.1-0.5% additive (as supplied) based upon total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.
