摘要:
A method of painting a substrate having an undercoat or intermediate coat, which comprises applying to the coated substrate (1) a water-borne clear paint comprising a mixture consisting of, per 100 parts (by weight) thereof, (A) 30 to 94 parts of a vinyl copolymer having an acid value of 5 to 100, a hydroxyl value of 20 to 100, a solubility parameter (δsp) of 9.0 to 13.0 and a number average molecular weight of 3,000 to 50,000, and which is prepared by copolymerising an ethylenic monomer having an acid group, an ethylenic monomer having a hydroxyl group and another, copolymerisable ethylenic monomer; (B) 5 to 40 parts of a cross-linking component; and (C) 1 to 30 parts of resin particles swollen with an organic solvent having a solubility parameter of 7.5 to 13.0, the swollen resin particles having an average particle size of 0.01 to 10 µm; and (2) (without curing the water-borne clear paint) a thermosetting clear paint comprising a mixture consisting of, per 100 parts (by weight) thereof, (D) 60 to 95 parts of a copolymer having a hydroxyl value of 20 to 100 and a solubility parameter not less than 0.3 different from that of the vinyl copolymer, and which is prepared by copolymerising an ethylenic monomer having a hydroxyl group and another, copolymerisable ethylenic monomer; and (E) 5 to 40 parts by weight of a cross-linking component.
摘要:
New and improved curable compositions useful as non-yellowing, acid resistant coatings for a variety of substrates and as adhesives and binders are disclosed. The curable compositions comprise a polymeric component comprising poly(C₁-C₆ alkyl acrylamidoglycolate) functional units and poly (active hydrogen) functional units and preferably an effective amount of a protic acid crosslinking catalyst. In preferred embodiments acid-catalyzed room temperature curable coating compositions are provided. The compositions may be cured effectively at lower temperatures without the use of amines or other toxic crosslinking agents and do not liberate formaldehyde on curing. A method for making poly(C₁-C₆ alkyl acrylamidoglycolate) functional polymers is also disclosed.

Die vorliegende Erfindung betrifft die Verwendung einer wäßrigen Dispersion, enthaltend
(A) ein carbonylgruppenhaltiges Copolymerisat aus monoolefinisch ungesättigten Verbindungen, von denen mindestens 10 Gew.% mit Hydrazidgruppen reagierende Carbonylgruppen auweisen und (B) Polyhydraziden, als Unterbelag eines mehrschichtigen Überzugs auf einem Substrat sowie ein Verfahren zu dessen Herstellung.
摘要:
An improved thermosetting coating composition comprises a film forming component and an amino compound, which cures by reaction between the amino compound and hydroxy functionality present on the film forming material. The curing is catalysed by an oligomeric hydroxy functional organophosphate ester of the formula: - wherein N = 1 or 2 and
R is selected from mono or dihydroxy radicals containing one or more ester linkages and having a molecular weight of from 120 to 1500.
