Nacure® XC-293

Based on proprietary acids. Acts as an adhesion promoter. Improves the adhesion of melamine crosslinked systems to metal, especially on aluminum substrates, and adhesion of thermoplastic and ambient cure coating formulations. Exhibits excellent humidity, corrosion resistance, good package stability and improved cure response of amino crosslinkers, particularly partially alkylated types. Is soluble in alcohols, glycol ethers and glycols. Can be used as the sole catalyst for partially alkylated or high-NH type melamines or in conjunction with strong acid catalysts for fully alkylated melamine systems. Applicable for general industrial, can- and coil coatings. Recommended level is 0.5-2.0% as supplied on total resin solids.
