Abstract

A title compn., with good storage stability, comprise (i) a polymer having reactive groups and (ii) a crosslinker capable of reacting with said reactive groups, wherein the crosslinker is encapsulated in a material having a Tg (measured by DSC, 2nd scan, 20 Deg per min) of from about 80-170 Deg. A powd. compn. comprising of Uralac P954 62, Uranox P 7121 4, encapsulated epoxidized linseed oil (with Tg 120 Deg; prepd. from the oil, Povidone K 30, and Na dodecylsulfonate) 31, a flow agent 2, and an antioxidant 1% showed free-flow ability after 2 wk at 40 Deg and gave cured film (180 Deg, 20 min) on Al plate with good adhesion.
