A crosslinkable coating composition comprising: ingredient A that has at least two protons that can be activated to form a Michael carbanion donor; ingredient B that functions as a Michael acceptor having at least two ethylenically unsaturated functionalities each activated by an electron-withdrawing group; and a dormant carbamate initiator of Formula (1) wherein Rand Rcan be independently selected from hydrogen, a linear or branched substituted or unsubstituted alkyl group having 1 to 22 carbon atoms; 1 to 8 carbon atoms; and Ais a cationic species or polymer and n is an integer equal or greater than 1 with the proviso that Ais not an acidic hydrogen; and optionally further comprising ammonium carbamate (HNRROC&#x2550;ONRR). The crosslinkable coating composition can be used for a variety of coating applications including nail coating compositions.

Wetting and anti-foaming agent

A coating composition containing a crosslinkable coating composition. The coating system comprises: ingredient A that has at least two protons that can be activated to form a Michael carbanion donor; ingredient B that functions as a Michael acceptor having at least two ethylenically unsaturated functionalities each activated by an electron-withdrawing group; and a catalyst system. In one embodiment, the catalyst system comprises diethyl carbonate, quaternary ammonium hydroxide or quaternary ammonium alkoxide, ethanol and 4-6 wt. % water. In another embodiment, the catalyst system comprises carbon dioxide, quaternary ammonium hydroxide or quaternary ammonium alkoxide, ethanol and 2-4 wt. % water. In certain embodiments, the coating composition optionally further comprising ammonium carbamate (HNRR+&#x2014;OC&#x2550;ONRR), wherein RRare each independently selected from hydrogen, a linear or branched substituted or unsubstituted alkyl group having 1 to 22 carbon atoms; 1 to 8 carbon atoms; 1 to 3 carbon atoms.

A polyamide composition for use in sealants, adhesives and high solids coatings.

Polyamide compositions for sealants and high solids paints

A wetting agent according to Formula (I): wherein Ris selected from a branched alkyl group or linear alkyl group or a cycloaliphatic group or an aromatic group, each having 6 to 15 carbon atoms; Ris selected from hydrogen, methyl, or ethyl; Ris selected from hydrogen, methyl, or ethyl; Ris selected from hydrogen, methyl, or ethyl; Ris selected from methyl or ethyl; x ranges from 0 to 5; y ranges from 0 to 10; z ranges from 1 to 10; with the proviso that when x ranges from 1 to 5, Ris different from R; and with the proviso that when x=0, Ris different from R. The wetting agent also imparts anti-foam properties to aqueous solutions while reducing surface tension.
