Blister Free 77

Surface active polymers in a solvent mixture. Acts as a defoamer. Effective deaeration is required for smooth film formation. Trapped air, pinholes can cause dirt retention and difficulties when topcoating as well as polishing. Apart from these surface defects frequently a reduction in gloss and a deterioration in water resistance are observed. Also the even formation of the wax layer with unsaturated polyesters is promoted.
