TMMGU system powder coating catalyst composition capable of providing texture effect, and powder coating

The invention discloses a TMMGU system powder coating catalyst composition capable of providing a texture effect, and a powder coating, and relates to the technical field of powder coatings. The powder coating catalyst composition comprises a tertiary amine compound and a sulfonic acid compound. According to the invention, different texture effects can be obtained by different selections of sulfonic acid compounds in the composition and tertiary amine compounds, the texture effects can be new water ripples, and the water ripples are not reported in TMMGU system powder coatings; and the texture can also be moire, and the difference from the moire powder coating reported in the prior art is that no epoxy compound is added. After the powder coating containing the catalyst composition is cured, the layout texture is clear and uniform, the continuity is good, the decorative effect is obvious, and the reproducibility is good. 本发明公开了一种可提供纹理效果的TMMGU体系粉末涂料催化剂组合物及粉末涂料，涉及粉末涂料技术领域，所述粉末涂料催化剂组合物包括叔胺类化合物和磺酸类化合物。本发明通过对组合物中磺酸
