Abstract
A curable phenolic resin composition comprises the reaction product of (a) a polyhydric compound of the formula <FORM:1068586/C3/1> where n is 1 or 2; (b) 10 to 40% by weight of (a) of phenol; and (c) at least one mole of formaldehyde per mole of phenolic OH in (a) and (b) in solution in a solvent volatile at the curing temperature. Reactant (a) may be obtained by reacting 2 moles of bisphenol A with one mole of epichlorohydrin or the diglycidyl ether of bisphenol A using an alkaline catalyst. Specified solvents for (c) are glycol ethers and ether-esters, MIK, diacetone alcohol and C1- 6 alkyl alcohols. Specified catalysts for the reaction include alkali and alkaline earth metal hydroxides, ammonium and tetraalkylammonium hydroxides, tertiary amines, hexamine and sodium amide. Acids may be added to the reaction product to accelerate curing e.g. phosphoric, sulphuric, hydrochloric, oxalic, citric or acetic. In the example (a) is obtained by reacting an epoxy material of epoxide equivalent 185 to 200 and M.W. 350 to 400, consisting predominantly of bisphenol A diglycidyl ether, with bisphenol A using lithium naphthenate as catalyst. The composition is used to coat steel panels by dipping and baking and may be employed as an internal coating for metal containers.ALSO:A curable phenolic resin coating composition comprises the reaction product of (a) a polyhydric compound of formula <FORM:1068586/B1-B2/1> where n is 1 or 2 (b) 10 to 40% by wt. of (a) of phenol, and (c) at least one mole of formaldehyde per mole of phenolic OH in (a) + (b) in solution in a solvent volatile at the curing temperature. Reactant (a) may be obtained by reacting 2 moles bisphenol A with 1 mole of its diglycidyl ether or epichlorohydrin. The composition may be used as an internal coating for metal containers and in the Example is applied to steel panels by dipping and baking at 400 DEG F. An alkaline catalyst may be used for the reaction and an acid catalyst for curing.
