USE & PERFORMANCE
Outstanding properties: Improved anti-blocking in aqueous coatings. It increases surface slip,
scratch resistance, abrasion resistance and provides a soft feel effect.
Recommended for products: architectural and leather coatings, printing inks and overprint var-
nishes
Concentrations used, wt%: 1-3% coatings (based on total formulation), 2-5% printing (based on
total formulation), 1-25% surface maintaining and protecting
Food approval FDA: 175.300/resinous and polymeric coatings, 176.180 components of paper and
paperboard in contact with dry food
