Abstract: A thermosetting coating or adhesive composition based on (A) at least one component selected from the group consisting of oligomeric and polymeric compounds containing at least one of the functional groups hydroxyl and epoxy groups, and (B) a polycarboxylic acid mixture comprising trimellitic acid and a major amount of at least one compound of one of the formulae (I) (II) (III) +TR wherein R, R' and R''', being the same or different, each represents a di- to hexavalent hydrocarbon radical having a total of from 1 to 12 carbon atoms, said radical containing from zero to 2 olefinic double bonds, said radical without double bonds being interrupted by up to 3 ether bridges: x and y which may be the same or different, each represents an integer of from 2 to 6; t an integer of from 1 to 5; and z and u, which may be the same or different, each represents zero or an integer of from 1 to 5 and a process for coating a substrate with said composition.

Abstract: An aqueous copolymer dispersion can be prepared, with a particular choice of the monomers and the ratios of their amounts, from styrene, esters of acrylic or methacrylic acid, vinyl esters, monomers containing hydroxyl groups, acrylic and/or methacrylic acid, acrylamide or methacrylamide and addition compounds of glycidyl esters of branched monocarboxylic acids with unsaturated carboxylic acids, by polymerization in the presence of an anionic emulsifier and a radical initiator and, if appropriate, a non-ionic emulsifier, which dispersion, in combination with an aminoplast resin, provides thermosetting coatings with excellent properties. These coatings provide highly elastic, weather-resistant, water-resistant surface coatings, which have high adhesion and are free of flaws, on metallic substrates.

Abstract: Thermosetting coating compsn. comprises (A) oligomers and/or polymers contg. OH and/or epoxy gps. and (B) a mixt. of polycarboxylic acids contg. trimellitic acid. The mixt. (B) contains >=1 cpd. contg. ester groups and having formulae (I)-(III): In the formulate, R,R' and R" are opt. branched hydrocarbon gps. of valency 2-6, pref. 2, contg. 1-12, pref. 2-6C and opt. having up to 2 olefinic double bonds or contg. up to 3 ether bonds; x and y are 2-6, t is 1-5 and z and n are 0 or 1-5. The compsn. pref. contains as third component (c) a polymer of fluorinated vinyl monomers contg. is not >=2F, the ratio of A+B:C being 9:1-1:9, pref. 3:1-1:3. Used for coating a variety of substrates e.g. ceramics, wood, glass, concrete, plastics and esp. metals. The compsn. is highly reactive and can be applied as a powder or in soln. It cures at 120-200 degrees C pref. 120-180 degrees C within 30 mins. (cf. 180-200 degrees C for prior art compsns.) Compsns. contg. component (c) are partic. suitable for coil-coating. The compsn. is storage stable and (B) is soluble even in weakly polar solvent.
