BLISTER FREE 75

Defoamer for solvent borne and water-based coating systems, silicone free

 

Chemical base:   Polymer in solvents mixture
     
Properties:   BLISTER FREE 75 is a product with interfacial activity, which suppresses the formation of entrapped air in coatings and printing inks, i.e. air bubbles are destroyed before the film dries. Therefore, cratering is prevented. In many cases levelling is improved.
     
Applications:   BLISTER FREE 75 shows very good defoaming properties in solvent borne:
  • NC-systems and NC-combinations
  • AC- and epoxy-systems
  • PU and air drying acrylic systems

BLISTER FREE 75 has very good defoaming effect in water-based coating systems based on the following binders:

  • Long oil alkyds
  • Medium oil alkyds
  • Acrylate/medium oil alkyds
  • Acrylate/long oil alkyds
  • Epoxides
