USE & PERFORMANCE
Outstanding properties: High-performance anti-cratering and flow-control properties, plus excel-
lent compatibility with solvent-borne resins. Prevents surface defects during paint application and
improves the resistance and appearance of the dry coating film. Adjusts the coating's surface ten-
sion, preventing defects caused by additives, contaminants and the base substrate. Prevents crater-
ing caused by insufficient cleaning of the substrate, particles of dirt or incompatible substances
(defoamers or silicone oils). Improves surface smoothness and slip, prevents floating. Silicone
free, substrate wetting and leveling additive with the improvement of intercoat adhesion. Effec-
tively prevents application-related film defects, in the case of roller, spray, and dip-coating, such as
craters, poor flow as well as variable wetting of the substrate due to dirt.
Recommended for polymers: acrylic, polyester/melamine, epoxy, PUR
Recommended for products: solvent-borne and solvent-free coatings, industrial and architectural
coatings
