USE & PERFORMANCE
o
Outstanding properties: Offers heat resistance up to 200 C, weather resistance and light stability,
resistant to solvents and chemicals. Offers resistance to most customary solvents used in the coat-
ings industry, also offers good chemical resistance. Colorfastness and weather resistance are excel-
lent. Posses excellent dispersing properties. The use in exterior applications is possible without
limitations. The coatings are recoatable.
Recommended for products: printing inks, wood lacquers, UV-curing coatings, coil coatings, lac-
quers on foils, aqueous wood, furniture varnishes, leather finishes
Concentrations used, wt%: 1-15
