DISPARLON SPX-20

  DISPARLON SPX-20 is an anti-popping/defoaming agent based on a vinyl polymer developed specifically for highly polar coatings like high-solid baking systems.

ADVANTAGES:
Effective particularly in preventing popping associated with high-solid coatings involving
methylated melamine, which is difficult to control with conventional additives.
In addition to the ability to prevent popping, these products can give leveling properties to the coating, thus eliminating the formation of Benard-cells.
Silicone free/good recoatability
