Abstract
A RMA crosslinkable coating composition, a method for the preparation thereof and a resulting coating having easy to clean properties useful in applications like graffiti resistant, sanitisable coatings and in flooring, the composition comprising RMA crosslinkable component with at least 2 RMA donor groups and at least 2 RMA acceptor groups characterized by having fatty components selected from the group of fatty acids, fatty alcohols, fatty amines, fatty thiols and dimeric fatty acid in an amount represented by an Oil Content OC between 0, preferably 4 and 40 wt %, and crosslinking density XLD of at least 1.4 a glass transition Tg of at least 290 in combination providing a easy to clean value ΔE less than 20. The invention also relates to RMA crosslinkable fatty resins for use in RMA crosslinkable top coatings.
