Product Application

Liquid Coatings

Special Features and Benefits

  • The additive is used as an anti-cratering and leveling additive in all solvent-borne and solvent-free 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-361 N does not cause turbidity in clear coats or haze in pigmented systems.

Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.

Powder Coatings

Special Features and Benefits

  • The additive combines the best anti-cratering effect with optimum leveling and DOI (distinctness of image).
  • Fish eyes and pinholes in the powder coating layer are prevented.
  • It does not cause haze in pigmented powder coatings and does not cause turbidity in powder clear coats.
  • Its low viscosity and good compatibility enable easy incorporation in the resin when producing the masterbatch.

Recommended Use
The additive is recommended for manufacturing resin masterbatches for powder coatings, especially for powder clear coats.

Incorporation and Processing Instructions
The additive is added to the powder coating resin at the end of the manufacturing process and mixed with the resin.

Printing Inks and Overprint Varnishes

Special Features and Benefits

  • The additive improves leveling and increases gloss in all solvent-free and aqueous UV-reactive printing inks and overprint varnishes.
  • It only causes a minor reduction in surface tension and does not negatively influence the overprinting capability.

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-361 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.

Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.
