The present disclosure relates to an isocyanate terminated saturated hydrocarbon polymer that can be used as a crosslinking agent in a coating composition. The coating composition can provide a composition that adheres well to resinous substrates. Also provided are coating composition comprising the crosslinking agent and methods for producing the adherent coating composition.

The present invention relates to an adhesion promoting cleaner solution for producing and adherent coating on a resinous substrate. The adhesion promoting cleaning solution comprises a telechelic diol in a carrier liquid such as an organic solvent. Also disclosed is a process of using the adhesion promoting cleaner solution to produce an adherent coating on a resinous substrate.

Adhesion promoting cleaner solution

A fast hardening clear coating composition for repairing a clear coat/color coat finish or a pigmented mono-coat of a vehicle comprising a film forming binder and an organic liquid carrier, where the binder contains a hydroxyl polymer component comprising (A) hydroxyl-containing acrylic polymer, (B) at least one hydroxyl-terminated component selected from the group consisting of (1) an organic diol having the formula 

The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors.

Polymerization of acrylic polymers in reactive diluents

The present invention is directed to a coating composition that when applied over untreated thermoplastic and thermosetting resinous substrates, produces an adherent coating thereon. The composition includes a crosslinkable component and a crosslinking component. 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&#x2014;(R&#x2014;NCO) wherein Ris a substituted or unsubstituted cycloaliphatic group, Ris independently selected from a direct bond, a straight aliphatic group or branched aliphatic group, and wherein n ranges from 2 to 10. The coating composition 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.

Adherent coating compositions for resinous substrates

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&#x2014;(R&#x2014;NCO)wherein Ris a substituted or unsubstituted cycloaliphatic group, Ris 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.
