Abstract: Reactive, hardenable polymer mixt. contains (A) epoxy cpds. and (B) polycarboxylic acid units. (B) contains (a) a cpd. of formula (I) or (Ia): (where R1 is the residue of an OH gp.-contg. polymeric polymsn. and/or condensn. prod. polyester having OH-no. 20-300 or phenoplast having OH-no. 100-800; R2 is the residue of an at least tetrabasic carboxylic acid contg. an esterifiable COOH gp. in o- or peri-position; R5 is as R2 or is the residue of an at least dibasic carboxylic acid contg. an esterifiable COOH gp. in the o- or periposition) and/or (b) an at least tetrabasic cyclic carboxylic acid cpd. contg. two o- or peri-COOH gps. or one anhydride gp. together with at least one R1 gp. and/or (c) a cpd. (I) or (Ia) in which the anhydride gps. are replaced, at least partly, by free acid and/or ester gps., and/or (d) a cpd. (b) in which the anhydride gps. of the polycarboxylic acid cpds. are replaced, at least partly, by free acid- and/or ester gps. The mixts., as solns. or powders, may be used as coating compsns., e.g. as stovable lacquers, primers, top lacquers, 1-layer lacquers, shock-drying systems for coil-coating in lacquering food tins. The mixts. can also be used as laminates, as protective coatings, e.g. for articles exposed to aggressive media, weathering, solvents, heat, 2-component hot melt- and thermosetting adhesives; as binders, e.g. for textiles, and as moulded resins, casting resins, putties, foams and insulating lacquers. The mixts. are stable, have high reactivity, can be crosslinked at 20 degrees C, and can be used as powders which cause no environmental pollution in use. Powder lacquers may be hardened by stoving at 100-180 degrees C in 30 min.

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.

Abstract: Single-layer coatings are based on a mixt. of (A) a synthetic polymerisation addn. or condensn. resin, and (B) a hono- and/or co-polymer of vinyl monomers with =4, pref. =2, F atoms, in which (A) is hardened at =30 degrees C, by (a) oxidative drying, (b) physical drying, (c) cross-linking of a 2-component system, (d) acid-hardening (e) high-energy radiation, or (f) a combination of at least two of (a) to (e) without soln. or melting of component (B). Used to provide protective coatings on wood, ceramics, glass, concrete, plastics or esp. on metals, in vehicles, and ship-building, on components exposed to fuels and solvents, household equipment, electrical components and thermally-stressed articles. Excellent adhesion is obtd. without application of primers or intermediates layers. The coatings can be deformed e.g by deep-drawing, profiling, embossing, etc. and show high resistance to weather and chemicals.

Abstract: A water soluble, reactive binder comprises >=3 units of (A) halogen free polycarboxylic acid mixts., (B) a salt forming material chosen from alkali(ne earth) metal and quaternary ammonium salts, organic bases and/or NH3, (Cl) OH contg. polymers and/or (C2) epoxy cpds. The binder hardens at low temps. and has high mechanical strength and chemical and light resistance. The binder has good storage stability and is used as a lacquer esp. an electroimmersion lacquer for metals. The lacquer has good adhesion and high weather stability. The compsn. may also be used in sealants, mouldings, foams, insulation varnishes and street markings.
