Abstract: Disclosed herein is a 2K clearcoat coating composition including (A) from 10% to 70% by weight of a first resin having at least one primary hydroxyl group; (B) from 2% to 40% by weight of a second resin including a resin (B-1) having at least one primary hydroxyl group and/or a resin (B-2) having at least one secondary hydroxyl group; and (C) a crosslinker including at least one polyisocyanate and at least one amino resin, and the weight percentages of components (A) and (B) are based on the total weight of the coating composition and the ratio by weight between components (A) and (B) is in a range of from 6:1 to 1:2. Further disclosed herein is an article coated by the coating composition and the article may have metal substrates.

Abstract: Disclosed herein is a silane-functional hardener for carboxyl-functional resins including at least one monomer and/or oligomer and/or polymer having at least one group represented by Formula I-(a) and/or Formula I-(b) and at least one group represented by Formula II-(a) and/or Formula II-(b): where, R1, R2 and R3 independently represent a C1-C18 alkyl group, C1-C6 alkoxyl group, phenyl group, aryl group, hydrogen atom, chlorine atom or fluorine atom and at least one of R1, R2 and R3 is a C1-C6 alkoxyl group, R4 represents a C1-C18 alkyl group, C1-C6 alkanol group, C1-C6 alkoxyl group, or hydrogen atom, R5 represents a hydrogen atom, C1-C18 alkyl group, or C1-C6 alkoxyl group, R6 represents a C2-C6 acyl group, C1-C18 alkylene group or arylene group and R7 represents a —NR4— group, C2-C6 acyl group, C1-C18 alkylene group, C1-C18 alkoxy group or arylene group.

Abstract: Disclosed herein is a dual-reactive composition including a). from 24% to 90% by weight of crosslinkable silane-functional monomer and/or oligomer and/or polymer; b). from 9% to 75% by weight of one monomer and/or unsaturated oligomer and/or unsaturated polymer; c). from 0.5% to 10% by weight of one initiator; and d). from 0.5% to 10% by weight of one catalyst, all weight percentages are based on the total weight of the coating composition and a film obtained from curing and drying of the coating composition as well as a substrate coated with the dual-reactive coating composition. Additionally disclosed herein is a process for preparing the dual-reactive coating composition and a roll-to-roll coating composition and a 1K clearcoat composition including the dual-reactive coating composition.
