USE & PERFORMANCE
Outstanding properties: Improved matting properties and scratch properties. Improved the degas-
sing and pigment wetting of powder coatings as well as the electrostatic charge during processing.
Acts as a surface modifier. Offers increased scratch resistance, significantly improves slip and
degassing properties, improves air release during cure preventing cratering.
Recommended for products: Recommended for powder coatings and aqueous coatings. Phase sta-
bility. Can be easily mixed into aqueous systems. Can be used in inks, coatings, mold release com-
pounds, lubricants and pigment dispersions.
Concentrations used, wt%: 0.5-40% (based on total formulation)
