A coating comprising the reaction product of a natural oil derived polyol, a lactide and a radiation curable moiety, such as a (meth)acrylate, are disclosed.

Radiation curable coating compositions comprising a lactide reaction product

Disclosed are heat releasable multi-component composite coatings. These coatings include an under coating and an over coating deposited over at least a portion of the under coating. The under coating is deposited from a coating composition that includes a film-forming resin and thermally expandable capsules having an average diameter of 5 to 25 &#x3bc;m. The over coating layer has a 60 degree gloss of no more than 60 gloss units.

Heat releasable composite coatings and related methods

Crosslinked coatings comprising a reaction product of a compound containing two or more active hydrogen groups and a lactide are disclosed, as are substrates coated therewith.

Crosslinked coatings comprising lactide

Star polymers prepared by reacting a highly branched polymer and either a lactone or lactam are disclosed. These star polymers find particular application as additives for powder coating compositions, to improve various performance properties thereof. Powder coating composition comprising the described star polymers are also disclosed.

Polymer additives for powder coatings

Comb polymers prepared by reacting an epoxy resin and a lactone are disclosed. These comb polymers find particular application as additives for powder coating compositions, to improve various performance properties thereof. Powder coating composition comprising the described comb polymers are also disclosed.

Epoxy polymer additives for powder coatings

Methods for making composite flakes are disclosed. The composite flakes are formed from particles and one or more monomers and/or resins or resin systems. The polymer matrix of the flakes is highly crosslinked and/or high molecular weight. Use of the particles in powder coatings is also disclosed.

Composite flakes and methods for making and using the same

Comb polymers prepared by reacting an acrylic polyol or a siloxane polyol with a lactone are disclosed. These comb polymers find particular application as additives for powder coating compositions, to improve various performance properties thereof. Powder coating composition comprising the described comb polymers are also disclosed.

A crosslinking agent that is an ungelled reaction product of (a) an aminoplast resin and (b) a carboxylic acid-containing compound wherein the crosslinking agent is essentially free of reactive carboxylic acid groups and has a glass transition temperature of at least 10&#xb0; C. is disclosed. Methods for preparing crosslinking agents are also disclosed. Further provided is a curable powder coating composition including a polymer having a glass transition temperature of at least 30&#xb0; C. containing reactive functional groups and the present crosslinking agent; a multilayer composite coating composition and substrates coated therewith are also disclosed.
