Disclosed are low temperature, moisture curable coating compositions, related coated substrates, and methods for coating a substrate. The coating compositions include an ungelled, secondary amine-containing Michael addition reaction product of reactants including a compound comprising more than one site of ethylenic unsaturation, and an aminofunctional silane.
摘要:
A one-package stable rubber based curable composition contains:(a) a functional rubber polymer selected from the group consisting of functional homopolymers of polybutadiene, isoprene or neoprene; functional copolymers of polybutadiene, isoprene and/or neoprene; and functional copolymers of polybutadiene, neoprene or isoprene with an aliphatic or alicyclic unsaturated hydrocarbon; and(b) a vulcanization system comprising sulfur, wherein the composition contains at least 15 parts of functional rubber polymer per 100 parts of composition and at least 15 parts of sulfur per 100 parts of the total amount of all rubber polymers in the composition, with the proviso that the cured composition has an elongation not exceeding 15 percent and the functional groups present on the functional rubber polymer of (a) remain essentially unreacted during cure of the composition.
摘要:
Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the coating as compared to a coating where no particles are present. Also, the difference between the refractive ranges from 1 to 1.5. A method for preparing a powder coating including the particles also is provided.

摘要:
Disclosed are improved curable powder coating compositions comprised of a particulate, film-forming mixture of a polymer having reactive functional groups, and a curing agent therefor having functional groups reactive with the functional groups of the polymer and present in an amount sufficient to cure the coating composition, wherein the inclusion of a particular polyester which has carboxylic acid functional groups improves adhesion to metal, particularly aluminum, and filiform corrosion resistance.
摘要:
Powder coating compositions having improved mar and scratch resistance are disclosed. The coatings generally comprise one or more particles that have been modified to render the particles more surface active. The improved resistance is achieved without affecting the appearance or mechanical performance of the coatings. Methods for using the coatings, and the substrates coated therewith, are also disclosed.
