    CPC classification number: C09D167/00 C08L2666/02 C08L2666/28 C09J167/00

    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.
