摘要:
A coated article which includes a cement fiberboard substrate and a radiation-curable coating system applied to the substrate. The coating system includes one or more olefinic compounds and one or more PVC dispersion resins, and may be provided in the form of one or more coating compositions that may be applied in one or more layers.
摘要:
A coated article which includes a cement fiberboard substrate and a radiation-curable nonaqueous coating system applied to the substrate. The coating system includes one or more olefinic compounds and one or more non-olefinic resins which are soluble or dispersible in the one or more olefinic compounds. The non-olefinic resins may be chlorinated or non-chlorinated.

摘要:
A coating system, a method of coating a substrate, and a coated substrate (e.g., a coated cement fiberboard article) include one or more latex polymers, an aliphatic epoxy resin system, optionally a silicate additive, and optionally one or more olefinic compounds and an initiator. The coating system may be applied in one or more layers and may be applied to all the surfaces of the substrate (e.g., the front side, back side and edges of a board). The coated substrate may then be coated with other optional coatings, e.g., decorative or protective topcoats.
摘要:
The bottom of a cement fiberboard article is coated by conveying the article across a gap between a first conveyor and second conveyer and applying a liquid radiation-curable coating system to at least the bottom surface of the article while the article passes over the gap. The coating system is radiation-cured to at least a reduced tack state before the coated surface contacts the second conveyor.

摘要:
A coated article and method of employing a water-based coating composition on a fiber cement composite substrate is provided. The coating composition contains: an epoxy resin, a crosslinker having epoxide-reactive functional groups, a latex polymer distinct from the epoxy resin, and water.

A method for coloring powders is provided that includes mixing a base powder and non-incorporated pigments. A colored powder composition having a base powder particle and at least a partial shell of non-incorporated pigments about the base powder particle is also provided. Articles having a coating of the colored powder composition are also provided.
摘要:
A method is provided for producing a modified addition polymer from an ethylenically unsaturated monomer composition that includes at least one monomer having hydroxyl or carboxyl functionality. The ethylenically unsaturated monomer composition, and a free radical initiator therefor, is dissolved in a solvent-free molten composition maintained at an addition polymerization temperature, the molten composition comprising a cyclic compound reactive via ring-opening with the hydroxyl or carboxyl functionality. The resulting material is useful in the manufacture of paints in liquid or powder form.
摘要:
An alkyd-type electrodepositable coating composition derived from the reaction of a base alkyd with ethylenically unsaturated monomers including an amine-functional monomer is provided with improved resistance to chipping by chemically incorporating in it by covalent bonding one or more chemical agents selected from the group of:(a) preformed elastomers having functional groups reactive with carboxyl or hydroxyl groups of acid and polyol alkyl precursors, and(b) an addition polymerizable monomer having primary and secondary ethylenic unsaturation.
