Product Application

Coatings industry
Special features and benefits
BYK-088 is a defoamer for all solvent-borne and solvent-free coating systems, especially aromatic-free systems.

Incorporation and processing instructions

  • To achieve optimal defoaming, the defoamer should be added to the millbase.
  • If it is incorporated at a later time, sufficient shear forces must be ensured in order to achieve good defoamer distribution and to prevent crater formation.

Printing inks
Special features and benefits
BYK-088 is a defoamer for all solvent-borne and solvent-free printing inks, especially UV systems.

Incorporation and processing instructions

  • To achieve optimal defoaming, the defoamer should be added to the millbase.
  • If it is incorporated at a later time, sufficient shear forces must be ensured in order to achieve good defoamer distribution and to prevent crater formation.

Thermosets
Special features and benefits

  • Air release agent to prevent foam and bubbles during the manufacture and application of ambient curing plastic applications.
  • Recommended for floorings and casting systems on polyurethane basis.

Incorporation and processing instructions
Incorporate into resin before adding the other components. Can also be added to complete systems.
Adhesives and sealants
Special features and benefits
BYK-088 is a defoamer for all solvent-borne and solvent-free adhesives and sealants, especially aromatic-free systems.

Incorporation and processing instructions
Incorporate into resin before adding the other components.
