Features and advantages:

VOK®- FL 3603 can improve the scratch resistance of waterborne coatings, and has no effect on the gloss and transparency. As alumina nanoparticles

Transparency and high gloss have no effect and can be applied with varnish or paint system. Even low dosage can provide long-term scratch resistance.

VOK®- FL 3603 can be used for waterborne and waterborne UV curing systems, as well as the following systems:

-Acrylic acid dispersion

-Self crosslinking acrylic dispersion

-Dispersion

-Polyurethane acrylic dispersion,

-Aliphatic polyester polyurethane dispersion.
