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 &#x394;E less than 20. The invention also relates to RMA crosslinkable fatty resins for use in RMA crosslinkable top coatings.

RMA crosslinkable compositions and RMA crosslinkable resins for easy to clean coatings

The invention relates to a method for dual curing a RMA crosslinkable resin coating, to RMA crosslinkable compositions and to resins for use in the method.

Method for curing a RMA crosslinkable resin coating, RMA crosslinkable compositions and resins for use therein

The invention relates to 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, said 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 &#x394;E less than 20. The invention also relates to RMA crosslinkable fatty resins for use in RMA crosslinkable top coatings.

A method for curing of a coating of RMA crosslinkable compositions, to RMA crosslinkable compositions and A method for curing of a coating of an RMA crosslinkable composition involving two or more different curing mechanisms, wherein the two or more different curing mechanisms involve a) RMA crosslinking in combination with a second crosslinking reaction between hydroxy groups on the RMA crosslinkable components with polyisocyanates or siloxanes; or b) RMA crosslinking in combination with a second crosslinking reaction with polyamines, with crosslinkable components comprising component B and/or with epoxy groups on the RMA crosslinkable components; or c) RMA crosslinking in combination with a second crosslinking reaction based on auto-oxidative drying of unsaturated groups on the RMA crosslinkable components; or d) RMA crosslinking in combination with a second radical crosslinking reaction of reactive components B on the RMA crosslinkable components; or f) combinations thereof.
