PURPOSE:To obtain a resin compsn. with excellent cavitation resistance and sand abrasion resistance by compounding a rubber-modified epoxy compd. and an aliph. polyamidepolyamine. CONSTITUTION:This resin compsn. comprises a rubber-modified epoxy compd. and an aliph. polyamidepolyamine as a curing agent. It is pref. that said resin compsn. contains an inorg. filler and/or polybutadiene rubber. In addition, it is pref. that said rubber-modified epoxy compd. contains 50-70wt.% polybutadiene, siloxane, fluoroalkyl or fluoroalkyl ether skeleton. Furthermore, it is pref. that said aliph. polyamide is a compd. of the formula (wherein m and n are each 1-100). It is pref. that said inorg. filler is an inorg. filler with a mean particle diameter of 8-20mu and/or a whisker or a mica filler the surface of which is treated with a coupling agent.
