Byk -071 Polysiloxanes BYK Chemie Defoamer / Antifoaming agent >> Silicone Coatings >> Solventborne Architectural / Decorative General Industrial /Maintenance Wood & Furniture Coatings Xylene Byk®- 071 is a solution of foam destroying polysiloxanes. BYK®-071 displays its optimum defoaming properties during production, filling and application of coatings. Best defoaming action is achieved in low polarity wood coatings. In high polarity wood coatings, BYK®-141 is the recommended defoamer. BYK®-071 does not cause turbidity in wood coatings and is even suitable to defoam "wet-look" systems. Additionally it improves levelling and partially increases surface slip. In curtain coating application, BYK®-071 does not cause instability of the curtain. The product also improves the orientation of flatting agents, leading to a more even flatting effect. It is used in industrial, architectural and wood & furniture coatings.
