• 应用

特点和优势

1. It can efficiently disperse and stabilize untreated and treated silica type matting powder.
2. It can strongly reduce viscosity and reduce thixotropy when dispersing matting powder, so that a higher content of matting powder can be added, and the addition and orientation of matting powder can be made more uniform.
3. 它不含挥发性溶剂，并且与紫外光固化涂层系统中常用的所有聚合物和单体具有优异的相容性.

• 推荐用途

紫外光固化涂层, 油墨.

添加量

根据供应形式计算:

无消光粉: 3-15%

有机颜料: 10-20%

高表面炭黑: 40-60%

*. 以上数据为实证剂量, 而最佳剂量需要通过一系列测试来确定.

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.

如果顺序错误, 可以通过后续添加进行补救, 但需要在高剪切条件下缓慢添加.
