USE & PERFORMANCE
Outstanding properties: Low concentrations reduce the surface tension resulting in improved
adhesion, excellent flow, and leveling. Reduce the dynamic surface tension, which improves sub-
strate wetting. When added to the millbase, it reduces the viscosity during pigment grinding,
increases gloss, color strength, and transparency, and reduces flooding/floating in pigment blends.
Recommended for polymers: acrylic, styrene acrylic, styrene butadiene, vinyl acetate-ethylene,
vinyl acrylic
Recommended for products: tapes, pressure sensitive adhesives, coated paper, wood and furniture
coatings, industrial coatings, printing ink, overprinting varnish
Concentrations used, wt%: 0.5-2%/coating, ink printing; 0.2/1.2/adhesives, sealants; 0.7-3%/glass
