摘要:
A coating composition including an unsaturated resin selected from polyesters, alkyds or combinations thereof; an alkoxy(meth)acrylic functional monomer, and a thermoplastic compound containing active hydrogen groups; a curing agent; and a curing promoter such as at least one metal drier.
摘要:
A method including applying a coating composition on a substrate to form a coating, wherein the coating has a first surface roughness; transferring a pattern to the coating to form a patterned coating, wherein the patterned coating has a second surface roughness different from the first surface roughness; and curing the patterned coating to form a cured coating with a desired level of gloss.
摘要:
A coated veneered article has at least one visible wood veneer layer coated with a multilayer finishing system comprising a coating layer nearest the veneer layer comprising a cationically polymerized moiety or moiety polymerized via cationic and free radical cure mechanisms, and an outermost coating layer comprising a free radically polymerized moiety. The article exhibits less veneer checking than a veneered article coated only with free radically polymerized coating layers.
摘要:
Soak-in and strike through on the exposed end grain portions of low density or porous wood substrates including alder, birch, pine, poplar, and soft maple are reduced by applying to the end grain a solvent-borne coating composition containing an (i) alkyd resin having a hydroxyl number less than about 150, (ii) acid catalyst and (iii) cross linker. The resin desirably has a number average molecular weight greater than about 2000, and may have a Gardner coloration less than about 3 or may be a short oil alkyd based on coconut oil. By using a reduced hydroxyl number alkyd resin, a reduced cross linker amount may be employed, thereby reducing formaldehyde evolution in compositions made with methylated amino resin cross linkers such as methylated melamine resins.

摘要:
Engineered wood product edges are protected by applying a two part edge sealing composition to at least one edge surface. The two part edge sealing composition can improve holdout, hide, and water resistance. An edge sealing system and substrates coated with the sealing system are provided.
摘要:
An aqueous coating composition containing (i) a polymer having one or more acetoacetyl-functional groups; and (ii) an acid-functional polymer, which may be the same as or distinct from the polymer comprising acetoacetyl-functional groups, wherein a nitrogen-free base has been used to neutralize or partially neutralize the acid-functionality on the polymer.

摘要:
Blooming may be reduced or eliminated in a low formaldehyde amino resin-crosslinkable coating composition by including in the composition, in addition to the ingredients necessary to form a crosslinked coating, an anti-blooming agent containing one or more of (i) an acid-functional polymer, (ii) ethylene glycol, propylene glycol or an ethylene glycol or propylene glycol polymer or copolymer, or (iii) for compositions containing the acidic catalyst p-toluene sulfonic acid (PTSA), a further acidic cure catalyst having greater hydrophobicity than PTSA. The anti-blooming agent has particular value in amino resin-crosslinkable alkyd resin formulations, but may be used in amino resin-crosslinkable coating compositions based on other film-forming polymers bearing amino resin-reactive functional groups including appropriately functionalized acrylic, polyester, vinyl and cellulose acetate butyrate (CAB) resins and nitrocellulose lacquers.
