CoatOSil FLX
CoatOSil FLX
CoatOSil® FLX is a polysiloxane resin modifier for silane/polysiloxane containing coatings, including hybrids. CoatOSil FLX coating modifier can be used as a “drop-in” replacement resin either in the grind paste of in the let down portion of a coating formulation.
The typical recommended dosage levels are between 0.1% wt to 10% wt in existing formulations on a total formulation basis.
