Specific Anti Foaming Agent

Specific Anti Foaming Agent I. Basic performance and application Specific antifoaming agent T603 specific 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 BYK961. II.
