Special Features and Benefits

  • The defoamer is used in all emulsion paints and plasters, especially in PVC ranges between 50 and 85.
  • It features an excellent cost/performance ratio and contains a paint-compatible silicone that reinforces the defoaming effect.

Recommended Use

  • The defoamer is particularly recommended for emulsion paints / exterior wall paints and emulsion plasters.
  • It may also be used in the production of emulsion binders.

Incorporation and Processing Instructions

  • Generally, 2/3 of the defoamer are added to the millbase and 1/3 is added to the letdown or the finished paint.
  • Sufficient shear forces are necessary for incorporation in order to avoid negative side effects.

Adhesives

Special Features and Benefits
The defoamer can be used used in any emulsion adhesive. It features an excellent cost/performance ratio and contains a compatible silicone that reinforces the defoaming effect.
Recommended Use

  • The defoamer is particularly recommended for emulsion adhesives on the basis of polyacrylates and polyurethanes.
  • It is also very effective in adhesives based on polyvinyl alcohol. It may also be used in the production of emulsion binders.

Incorporation and Processing Instructions

  • The defoamer should be added to the binder as early as possible.
  • Sufficient shear forces are necessary for incorporation in order to avoid negative side effects.
