Features & Benefits

Key Attributes

Effective deaeration is required for smooth film formation and complete deaeration. Entrapped air, pinholes can cause dirt retention and difficulties when topcoating and polishing. Apart from these surface defects frequently a reduction in gloss and a deterioration in water resistance are observed. BLISTER FREE 77 defoams intensively and strongly reduces blisters. Also the even formation of the wax layer with unsaturated polyesters is promoted. BLISTER FREE 77 is effective in wax containing as well as in wax free systems.
