Patent GB-824335-A (GB)
Title: Compositions comprising reaction products of methylol-aminotriazine allyl ethers with -a:-ß-unsaturated compounds and capable of drying at room temperature
IPC: C09D4/00
Filed: 1956-07-26
Abstract: Coating compositions capable of hardening throughout at room temperature comprise a metal drier, a peroxide and a condensation product of a methylol-aminotriazine allyl ether containing at least 2 amino groups and at least 2 allyl groups with an alpha, beta-unsaturated compound containing only one group capable of condensing with the methylolaminotriazine allyl ether.  Pigments, e.g. titanium dioxide, and further polymerizable components may also be present, e.g. unsaturated polyester resins and styrene. The peroxide may be added at the time of applying the coating by the injector action of the air stream of a spraying gun.  The compositions may be applied to polyester-glass fibre laminates or glass plates.  For test purposes, the glass plates are coated by a doctor roll, by pouring or by casting.  Specifications 611,012 and 753,568, [both in Group IV (a)], are referred to.ALSO:Compositions capable of hardening throughout at room temperature comprise a metal drier, a peroxide and a condensation product of a methylol-aminotriazine allyl ether containing at least 2-amino groups and at least 2-allyl groups with an alpha, beta unsaturated compound containing only one group capable of condensing with the methylol-aminotriazine allyl ether.  As the alpha-beta unsaturated compound there may be used compounds containing carboxyl, hydroxyl, acid chloride, acid amide, amino or isocyanate groups such as acrylic.  crotonic or cinnamic acids or their alkyl, aryl, halogeno or heterocyclic substitution products, sorbic acid, 1-cyclohexene-1-carboxylic acid; or the monoesters of di-carboxylic acids such as maleic, fumaric, mesaconic or citraconic acids with unsaturated monohydric alcohols such as allyl alcohol; or polyesters containing only one carboxyl or hydroxyl group per molecule derived from unsaturated dicarboxylic acids or from polyvalent alcohols and unsaturated monocarboxylic acids, e.g. glycol monoacrylic acid ester or glycerine diacrylic acid ester; or there may be used acrylamide, vinylamine, divinylamine or acrylic acid chloride.  The condensation reaction between the methylol-amino-triazine allyl ether and the alpha, beta-unsaturated compounds may be carried out simply by heating under reduced pressure and in the presence of a polymerization stabilizer, e.g. hydroquinone.  The metal drier is preferably a cobalt drier, e.g. cobalt naphthenate or octoate and the peroxide may be benzoyl, ditertiary butyl or methyl ethyl ketone per oxides or hydroxy cyclohexyl hydroperoxide.  The hardenable composition may also comprise titanium dioxide and a polymerizable monomeric and/or polymeric compound such as styrene, divinyl benzene and substitution products, vinyl esters, ethers or halides; or diallyl phthalate, triallyl cyanurate. allylglycide, diallylamine or triallylamine; acrylic and methacrylic acids or their esters, e.g. butyl methacrylate, acrylonitrile or diallyl maleate; or unsaturated polyesters such as reaction products of maleic or fumaric acids with glycols.  The compositions may be used to produce coatings, films or mouldable bodies which harden at raised or even room temperatures. Specifications 611,012 and 753,568 are referred to.
