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.
