    Abstract: PROBLEM TO BE SOLVED: To obtain a coating compsn. which gives a coating film improved in outdoor durability by combining the first component having carbamic ester groups and urea groups (or groups convertible into urea groups) with the second component comprising a substd. alkoxymethylurea cross-linker reactive with the functional groups of the former component. SOLUTION: The first component is an oligomer having the above-described functional groups and a mol.wt. of 148-2,000 and/or a polymer having the above- described functional groups and a mol.wt. of 2,000 or higher, examples being polyester, epoxy, alkyd, urethane, acrylic, polyamide, and polsilane polymers. For example, it is a polymer having carbamic ester groups and repeating units represented by the formula (wherein R is H or methyl; R' is H, alkyl, or cycloalkyl; L is a divalent linking group; A is at least one unit derived from an ethylenically unsatd. monomer; x is 10-90%; and y is 90-10%). A pref. example of the second component is a 1-4C alkoxymethylurea.

    Abstract: PROBLEM TO BE SOLVED: To provide a curable coating compsn. which can provide a coating having excellent resistance to environmental corrosion and high flexibility. SOLUTION: This curable coating compsn. comprises the following components (A) and (B): (A) A carbamate or urea functional compd. which is a reaction product between a mixture comprising the following compds. (1) and (2), (1) a compd. which is a reaction product between the following compds. (a) and (b) and has a carbamate group or a urea group (a group convertible to a carbamate or urea group) and a hydroxyl functional group, (a) a compd. contg. a carbamate or urea group (a group convertible to a carbamate or urea group) and an active hydrogen group reactive with a lactone or a hydroxycarboxylic acid and (b) a lactone or a hydroxycarboxylic acid, and a (2) a compound which is reactive with the hydroxyl group on a plurality of molecules of the compd. (A) (1) and unreactive with the carbamate or urea group on the compd. (A) (1); and (B) a compd. having a plurality of groups reactive with a carbamate or urea.

    Abstract: The invention provides a powder slurry composition comprising a first solid particulate component (a) dispersed in a crosslinking component (b) having at least one crosslinking resin which is liquid at 20.degree.C. First component (a) is in solid particulate form having an average particle size of from 3 to 30 microns. Component (a) has a compound (i) having a T g > 40.degree.C and at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group appended thereto. Crosslinking component (b) has at least one crosslinking resin (i) which is liquid at 20.degree.C. Most preferably, crosslinking component (b) will further include a self-crosslinking aminoplast resin (ii) having at least two aminoplast groups and at least two groups which are nonreactive with solid particulate first component (a) but which are reactiv e with said aminoplast groups. The powder slurry composition of the invention has a VOC of less than 1.0 lbs./gal and provides performance and application improvements over the prior art

    Abstract: A crosslinking agent comprising one or more carbamate groups or groups convertible to carbamate and two or more polyfunctional amino moieties having the formula ,wherein L is selected from the group consisting of alkyl or aryl, cycloalkyl and alkylaryl having a carbon chain length between 1 and 6 carbon atoms and N is a polyfunctional amino moiety. L may also have additional bridging groups such as eaters, ethers, ureas, or urethanes groups. Also included is a method of making the croselinker, a coating composition containing the crosslinker and a method for coating a substrate with the composition.
