ADHERENT COATING COMPOSITIONS FOR RESINOUS SUBSTRATES |
摘要 |
<p>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: R1—(R2—NCO)n wherein R1 is a substituted or unsubstituted cycloaliphatic group, R2 is 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.</p> |
