antifoaming agent

Product Description

I. Basic performance and application
T**3 antifoaming agent can clean the powder of the air hole which is caused by powder containing water and iron, aluminum or other castings containing water and have good effect on increasing hardness and resisting scratch and adhesion, specially for the large area of foaming on iron casting, aluminum casting or other heavier workpieces. It is applicable to various powders and enjoys more effect as transparent powder, similar with BYK**1.
