Byk -085 Methylalkylpolysiloxane BYK Chemie Defoamer / Antifoaming agent >> Silicone Flow / Levelling agent >> Silicone Scratch/ Srcub/ Mar resistance agent >> Silicone-based Slip control >> Silicone Coatings >> Solventborne Byk® -085 is a methylalkylpolysiloxane. Silicone defoamer to prevent foam and bubble formation arising during paint production and application in non-polar to high polarity solvent-based systems. BYK®-085 improves the surface properties of coatings, with particular emphasis upon levelling, increases surface slip and thus improves scratch and mar resistance. Formation of Bénard cells is prevented and orientation of flatting agents is improved. BYK®-085 does not cause dewetting or defects in intercoat adhesion when recoated. BYK®-085 is the solvent-free version of BYK®-077 and is used especially in systems in which solvent-free additives are requested or where a special solvent requirement exists. Methylalkylpolysiloxane. Used in coatings. Prevents foam and bubble formation. Offers improved levelling. Provides increased surface slip. Possesses improved scratch and mar resistance.
