Described herein is a coating composition including one or more (meth)acrylic polymers including moieties of formula (I)*—C(═O)—O—CH—Si(R)(R)  (I)where R=methoxy; R=an alkyl group containing 1 to 4 carbon atoms or an alkoxy group containing 1 to 4 carbon atoms; x is 0 or 1; and the asterisk * denotes the position at which the moiety of formula (I) is attached to the polymeric backbone of the (meth)acrylic polymer; further containing one or more catalysts of formula (II)HC—C(R)(R)—C(═O)—OM  (II)where Rand R=alkyl groups containing 1 to 6 carbon atoms, with the proviso that the sum of the number of carbon atoms in residues Rand Rranges from 2 to 7, and M=for Li, K or Na, and further containing one or more aprotic organic solvents.

Coating compositions containing (meth)acrylic resins having silane groups

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a non-polar catalyst. A second layer of a second cure coating composition can have a second hydroxy-functional resin, a second crosslinking agent, and a polar catalyst. The non-polar catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The polar catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The polarity of the catalysts can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.

Low temperature cure coating formed via polarity-facilitated catalyst migration between layers in a double layer curing mechanism

The present invention relates to a nonaqueous coating material composition comprising at least one compound (A) having at least two amino groups and at least one oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups. Compound (B) is obtained using at least one monomer (B1) of formula (I) where R-R, A, X, Z, and Y are as set forth in the specification and at least two different comonomers (B2) and (B3) which are each different from the monomer (B1). The present invention further provides the coatings produced from these coating material compositions, and also the use thereof.

Coating material compositions and low-temperature-curable coatings produced therefrom, and use thereof

A nonaqueous coating material composition and coatings thereof are provided. The composition contains an oligomeric and/or polymeric compound (A) having at least two hydroxyl groups, an oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups of formula (I'), and a catalyst (D) where # stands for the attachment to the polymer backbone and
