B618 silicon dioxide 1. Optimal matting effciency 2. Inorganic surface treatment. 3. Counter type of OK500.

B618 silicon dioxide 

This grade is good counter type to OK500 Matting agent.

   In order to meet the clients’ demand for using the organic surface treatment matting agent, through our technical research department, now we recommend a serie of new type matting agent for coating production. They have high transparent, high matting effection and dipsersion, with the good arrangement and handfeeling. Its particle size surface is treated by organic, it can meet the clients maximum demand.

Application characters

1,  High matting effection, good compatible with the resins.

2,   Low oil absorption, small , it can be widely used in the low VOC systems.

3,  It is directly to add into the coating systems, easy to disperse, specilally not easy to settlement and agglomeration;

4,  Not foam stable to the curtaining .

5,  It can improve the anti-scrubble and not effect the coatings mechanism character. It can have the excellence application and also can save a lot on the cost.
