Abstract

A lacquer comprises a solution in an organic solvent of a polyester which may contain amide, imide or ether groups, and at least one cross-linking agent, wherein a part of the polyhydric alcohol component used to prepare said polyester consists of one or more dimeric or polymeric fatty alcohols prepared by the reduction of the corresponding dimeric or polymeric fatty acids, or their esters, or addition compounds of said acids or esters with monomeric vinyl compounds. The content of dimeric or polymeric fatty alcohols is preferably between 7 and 25% of the polyester. Polyhydric alcohols for preparing the polyesters may be: ethylene glycol, glycerine, butane, 1,4-diol, neopentyl glycol, trimethylolpropane and pentaerythritol. Polycarboxylic acids may be: isophthalic, terephthalic and trimellitic acids. Solvents may be esters, ketones, glycol ethers and hydrocarbons. Cross-linking agents may be: phenolic resins, aminoplasts and polyisocyanates. In Example (1) a dimeric fatty alcohol prepared from dimerized unsaturated fatty acids of chain length C14 to C22 was mixed with ethylene glycol, butane 1,4-diol and isophthalic acid. Glycerine and tall oil fatty acids were added and the polyester obtained dissolved in solvent naphtha and mixed with a solution of butylated melamine-formaldehyde resin in butanol, to produce a lacquer. In Example (3) a polyester prepared from the dimeric fatty alcohol of Example (1). ethylene glycol, glycerine and dimethyl terephthalate was reacted with tolylene diisocyanate partly mixed with phenol in xylene and ethylene glycol acetate.ALSO:Electric windings are coated by dipping in a lacquer comprising a solution in an organic solvent of a polyester which may contain amide, imide or ether groups, and at least one cross-linking agent, wherein a part of the polyhydric alcohol component used to prepare said polyester consists of one or more dimeric or polymeric fatty alcohols prepared by the reduction of the corresponding dimeric or polymeric fatty acids or their esters, or addition compounds of said acids or esters with monomeric vinyl compounds. The content of dimeric or polymeric fatty alcohols is preferably between 7% and 25% of the polyester. Polyhydric alcohols for preparing the polyesters may be: ethylene glycol, glycerine, butane 1, 4-diol, neopentyl glycol, trimethylolpropane and pentaerythritol. Polycarboxylic acids may be: isophthalic, terephthalic and trimellitic acids. Solvents may be esters, ketones, glycol ethers and hydrocarbons. Cross-linking agents may be: phenolic resins, aminoplasts and polyisocyanates. In Example (1) a dimeric fatty alcohol prepared from dimerized unsaturated fatty acids of chain length C14 to C22 was mixed with ethylene glycol, butane 1,4-diol and isophthalic acid. Glycerine and tall oil fatty acids were added and the polyester obtained dissolved in solvent naphtha and mixed with a solution of butylated melamineformaldehyde resin in butanol, to produce a lacquer.
