New developments in solventless polyester varnishes

Salient features in the formulation of solventless varnishes are discussed. Results of a laboratory investigation of a number of experimental solventless products are presented. Selected physical properties of solventless and solvent-type varnishes are compared. Particular attention is given to overcoming the low build and embrittlement characteristics while maintaining the high bond strength and excellent insulating properties of solventless varnishes.<
