The use of additives in epoxy flooring is a very common problem, in which the additives are equivalent to catalysts. If used properly, it will have an inestimable effect. Once used poorly, it will have the opposite effect: 1) dispersant epoxy flooring paint, filling content, teaching volume is relatively high, when dispersed, the effect will be different. Dispersion, low efficiency, floatation and blurring are easy to occur. Common methods to improve wetting dispersant should be added. Glycolate dispersant has ideal wettability, low education, dispersion, anti-float and anti-blur effect. It also improves the gloss of the coating, promotes leveling and prevents the precipitation effect of the coating. 2 ）耐磨环氧自流平地坪涂料剂，由于少无溶剂环氧地坪漆耐磨的溶剂含量和不含挥发性溶剂，油漆教高的表面张力，穷人的建设后润湿基材，练级差，易发生剥离涂层，刷痕，波纹，火山口等表面针子状态的缺陷。因此，受流平剂添加，减少涂料的表面张力，延长时间的流动，改善流平性能。
2) Wear-resistant epoxy self-leveling floor paint, due to less solvent-free epoxy floor paint wear-resistant solvent content and no volatile solvents, paint teaches high surface tension, poor construction wetting base material, poor training, easy to peel coating, brush marks, ripples, craters and other surface needle defects. Therefore, the addition of leveling agent reduces the surface tension of the coating, prolongs the flow time and improves the leveling performance.
3) Defoamers contain a variety of surface activity for wear-resistant materials and are easy to foam epoxy floor coatings; cement mortar substrates have many pores, which will be replaced by thin film coatings left in the air; mechanical mixing and scraper coating for construction cause a large amount of air to enter the film; and their paint viscosity, stable bubbles in the shadow. In the film, it is not easy to discharge, these factors make the coating should be added accelerated gas discharge defoamer, reduce needle son, fish eye and other defects.
