    • 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 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 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.
    • 本发明涉及一种涂覆组合物,当涂覆在未处理的热塑性和热固性树脂基材上时,在其上产生粘附涂层。 组合物包括可交联组分和交联组分。 可交联组分包括含有至少一种由单体混合物聚合的可交联共聚物的聚合物混合物,所述单体混合物包含平均1至10个,优选1至4个,更优选1至2个羟基的烯属不饱和单体和饱和烃聚合物。 可交联组分包括一种或多种下式的脂环族多异氰酸酯:R 1 - (R 2 -NCO)n N其中R 1 取代或未取代的脂环族基团,R 2独立地选自直接键合,直链脂族基团或支链脂族基团,并且其中n为2-10。涂料组合物 非常适合于在烯烃基材上生产粘合涂料,例如在汽车和一般商业应用中使用的那些,而不需要对树脂基材进行任何预处理。
