BYK® -051

Solution of foam destroying polymers, silicone-free. Acts as a silicone-free, good compatible, defoamer for solvent-borne and solvent-free systems. Exhibits optimal efficiency in polar systems. Also exhibits less pronounced defoaming activity in non-polar systems. Due to its very good compatibility, it typically will not reduce transparency of overprint varnishes. Does not causes craters in typical formulations. Used in industrial, automotive, protective, architectural, wood and furniture and coil coatings, in printing inks and overprint varnishes. Its recommended dosage level is 0.05-0.5%.
