• 应用

特点和优势

1. The additive deflocculates the pigment through steric stabilization, and it also makes the pigment particles carry the same charge. The resulting repulsive effect and steric stabilization prevent the pigment from coarsening, thereby eliminating the problem of floating color in systems containing multiple pigments.
2. Due to the small particle size of the deflocculated pigment, high gloss can be obtained and color strength can be enhanced. 另外, the transparency of transparent pigments and the hiding power of opaque pigments can also be improved. Due to the reduction in viscosity, the leveling performance is improved and the amount of pigment added can be increased.

公司注册和加工说明

实现最佳性能, 应先将添加剂添加到研磨中, 其次是颜料. 预混合研磨的树脂和溶剂成分, 然后在搅拌的同时慢慢加入添加剂. 在添加剂充分混合之前不要添加颜料.
