USE & PERFORMANCE
Outstanding properties: Increased surface protection and a matting effect. Offers very good stor-
age stability in the finished polish, without any settling or creaming. The additive has a dirt-repel-
lent effect and adds filling capacity to the system. Abrasion resistance is improved, black heel
markings are reduced, and the floor is quickly ready for foot traffic. Offers very good scratch and
mar resistance. Exhibits a smooth, soft surface feel, and easy dispersibility. Imparts very good in-
can stability. Offers smooth and silky feel. Amine-free. Offers uniform matting.
Recommended for polymers: alkyd resins, acrylics and acrylic copolymers, polyesters, PU, cellu-
losic resins, PVC
Recommended for products: soft flooring like parquet, PVC, linoleum, rubber, wood and furniture
coatings. Used for solvent-borne and water-borne coatings
