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

    • The present invention is directed to a method of producing an adherent coating over untreated thermoplastic and thermosetting resinous substrates from a coating composition that includes a crosslinkable component and a crosslinking component that are mixed prior to application and applied over the substrate. The crosslinkable component includes a polymeric mix containing at least one crosslinkable copolymer polymerized from a monomer mixture comprising one or more ethylenically unsaturated monomers having on average 1 to 10, preferably 1 to 4 and more preferably 1 to 2 hydroxyl groups and a saturated hydrocarbon polymer. The crosslinkable component includes one or more cycloaliphatic polyisocyanate of the formula: R 1 (R 2 -NCO) n wherein R 1 is a substituted or unsubstituted cycloaliphatic group, R 2 is independently selected from a direct bond, a straight aliphatic group or branched aliphatic group, and wherein n ranges from 2 to 10. The method is well suited to produce adherent coatings on olefinic substrates such as those used in automotive and general commercial application without any pretreatment of the resinous substrates.
