Melamine formaldehyde resin composition, coating composition containing melamine formaldehyde resin composition, coating and application of melamine formaldehyde resin composition and coating

The invention provides a melamino-formaldehyde resin composition, a coating composition containing the melamino-formaldehyde resin composition, a coating and application of the melamino-formaldehyde resin composition and the coating. In a Fourier transform infrared (FT-IR) spectrum of the melamine formaldehyde resin composition, a ratio of a first peak intensity at 3334 cm to 3344 cm to a second peak intensity at 1072 cm to 1074 cm is less than or equal to 0.021. In addition, the invention further provides a coating composition containing the melamino-formaldehyde resin composition, a coating and application. By controlling the relative ratio of the first peak strength to the second peak strength, a coating can have excellent glossiness, excellent chemical resistance, proper hardness and good adhesive force, and the overall performance of the coating and an application product is improved. 本发明提供一种三聚氰胺甲醛树脂组合物、包含其的涂料组合物、涂层及其应用。于所述三聚氰胺甲醛树脂组合物的傅里叶变换红外(FT-IR)光谱中，在3334cm-1至3344cm-1处的第一峰值强度相对
