摘要:
Disclosed is a polyester polymer prepared from a reaction mixture comprising a polyacid component and a polyol component that comprises lignin. Residues of lignin are incorporated into the backbone of the polyester polymer. Coatings comprising the same and substrates coated at least in part with such coatings are also disclosed.
摘要:
Coated sheet materials having high solar reflective index and corrosion resistance, and methods of making such coated sheet materials, are disclosed. In certain embodiments, the sheet materials comprise metal such as galvanized steel roofing sheets, and the coating is deposited from a latex resin.
摘要:
Waterborne primer coating compositions are applied to sheet metal substrates and rapidly cured. The primer coating compositions contain water, a latex resin and corrosion-inhibiting particles. The primer coating compositions may be applied to the metal sheets and rapidly cured at a rolling mill, followed by coiling of the coated sheets.

摘要:
A composition that includes a fluorine-containing copolymer containing at least 30 mol % of residues having the following alternating structural unit: -[DM-AM]-where DM represents a residue from a donor monomer having the following structure (I): R1 is linear or branched C1 to C4 alkyl; R2 is selected from methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and AM represents an acceptor monomer. The copolymer contains at least 5 wt.% fluorine. The composition may include co-reactive functional groups and may be a thermosetting composition, which can be used to coat a substrate. The thermosetting composition may be part of a multi-component composite coating composition that includes a base coat deposited from a pigmented film-forming composition and a substantially pigment free top coat applied over at least a portion of the base coat.
