    Abstract: The invention pertains to a colorless ketimine or an adduct thereof displaying excellent color stability and usable as a cross-linking agent in a curable coating, impregnating, sealing or bonding composition wherein the ketimine is the adduct of a polyamine having a primary and a secondary amino group and containing at least 3 carbon atoms in a linear chain between both amino groups, and a ketone containing not more than 8 carbon atoms and having methylene groups adjacent to the carbonyl group. The invention also pertains to a process for preparing the ketimine and to the use of the ketimine in a curable composition.

    Abstract: This application discloses dimethyl ether propelled water based aerosol compositions. Classes of aqueous thickeners are described herein which are suitable for use in aqueous aerosol coating compositions. The thickeners lose their thickening capability in the presence of dimethyl ether which is the aerosol propellant employed, and thus allows a low enough temporary viscosity to afford suitable flow and breakup when dispensed in spray form from an aerosol dispenser. On evaporation of the dimethyl ether during the spraying process, enough of the dimethyl ether is lost to allow the thickener to regain its thickening capability. High gloss, thick film, aerosol paints can thus be achieved.

    Abstract translation: 本申请公开了二甲醚推进水基气溶胶组合物。 本文描述了适用于水性气溶胶涂料组合物的水性增稠剂类。 在使用气溶胶推进剂的二甲醚存在下，增稠剂失去其增稠能力，因此允许足够低的临时粘度，以便从气溶胶分配器以喷雾形式分配时可提供合适的流动和分解。 在喷雾过程中二甲醚的蒸发过程中，足够的二甲醚损失，使得增稠剂能够恢复其增稠能力。 因此可以实现高光泽，厚膜，气溶胶涂料。
