				Silicone levelling additive with defoaming action.  It improves the surface properties of solvent-based coatings, with particular emphasis upon levelling.  Causing only a slight surface tension reduction, in contrast to most silicone additives it does not stabilize foam and can even impart defoaming action.  BYK-325 increases surface slip and thus improves scratch and mar resistance.  Formation of Beard cells is prevented and orientation of flatting agents is improved. BYK-325 prevents ghosting (wipe-marks) if recoated with the same paint.  It does not cause dewetting and intercoat adhesion problems.  In most solvent-based systems, BYK-325 demonstrates better compatibility than BYK-320 therefore it does not cause turbidity in clear coats, but reduces hazing.  |
