Coating agent can reduce the surface tension of the coating provides efficient silicone surface aids for good wetting and good shrink proof properties of the substrate with poor wettability. It also increases surface smoothness, scratch resistance and anti adhesion. Improved dust and spray receptivity, and allowed higher film thickness to remain on the vertical surface. It reduces the airflow sensitivity in wood coatings and furniture coatings, prevents Bernard formation and improves the orientation of matting agents.
