Crosslinkable hydroxy terminated polydiene polymer coating compositions for use on substrates and a process for preparing them

摘要: A crosslinkable composition for coating primed and unprimed substrates comprising from 10 to 80 percent by weight of a hydroxy functional polydiene polymer having functionality at least 1.3, 8 60 an amino resin crosslinking agent, 2 40 reinforcing agent. The invention also encompasses process make such compositions partially reacting the three components 0.5 hours 120° C., optionally in presence small amount catalyst, give phase stable subsequently completely baking on substrate. painting substrate which comprises priming with primer selected group consisting epoxy primers polyester primers, applying basecoat over clearcoat dihydroxy polydiene-based clearcoats, acrylic clearcoats.
