HSR_additives (high scratch resistance)

STONE HSR_products are additives for UV varnishes that increase the scratch resistance and the abrasion resistance of the varnish. They are compatible with existing formulations. For example, a reactive diluent is modified in that way it is significantly more scratch-resistant. The rheology of the treated substance increases slightly, the compatibility of these remains.
