Abstract

Glycidyl ethers soluble in organic solvents which can be cured at room temperatures to give resinous products having improved resistance to corrosion &c. when used as coating compositions are obtained by reacting the glycidyl ether at above 50 DEG C. with an organic compound having at least three active hydrogen atoms which are attached to the nitrogen atoms of an aromatic diamine or which are present in the form of alcoholic or phenolic hydroxyl groups of a phenol-aldehyde resin having at least three phenolic OH groups in the molecule or 2 phenolic hydroxyl groups and in addition at least one methylol group. The reaction is maintained until the viscosity is constant and the soluble product is cured by addition of the usual aliphatic polyamine curing agents, e.g. ethylene diamine, diethylene triamine or the adduct thereof with a glycidyl ether; reduced quantities of curing agent are required as compared with glycidyl ethers which have not been subjected to the solubilizing treatment. In examples 2 parts m-phenylenediamine were added to 100 parts of a glycidyl ether dissolved in toluene and the solution heated to 120-125 DEG C. for 2 hours. After cooling the solution was diluted with a mixture of equal parts of methyl isobutyl ketone cellosolve and toluene and after the addition of 1.5 parts ethylene diamine per 100 parts reaction product was sprayed on to steel panels; the film obtained after hardening for a week at 23 DEG C. was found to have a pencil hardness of 4H. In Example 2 a phenol-formaldehyde resin having an average per mol. of 6 phenolic OH groups, 4.2 CH2OH groups and 1.8 DH2OC4H9 groups was used as the solubilizing agent. Specification 691,543 is referred to.
