• Features and Advantages:

  • It has the properties of self-emulsification, easy dispersion, strong versatility, good compatibility, and low dosage.
  • It performs defoaming and foam suppression without affecting gloss and leveling, without impacting recoatability, and without causing craters. It does not produce surface defects or affect film formation.
  • It has particularly good effects on water-based coating systems, and possesses excellent heat resistance and chemical stability, with no impact on adhesion.

• Application Fields:
  Suitable for anti-corrosion and marine coatings, architectural coatings, automotive production line coatings, automotive refinish paints, can coatings, coil coatings, wood and furniture coatings, paper coatings, and water-based adhesives, etc.

• Recommended Dosage:

  • In the coating industry: The dosage of the additive (in as-supplied form) is 0.1% - 1.0% based on the total formulation.
  • In adhesives: The dosage of the additive (in as-supplied form) is 0.05% - 1.0% based on the total formulation.

• Addition Method:
  This additive can be incorporated at any stage of production. It is beneficial to add the defoamer in two portions: 2/3 of the defoamer is added to the millbase, and 1/3 is added during or after the letdown stage.

• Packaging Specifications:
  Available in 30 kg/60 kg/200 kg drums.

• Storage and Transportation:
  This product is not a dangerous good, non-toxic, and non-flammable. It should be stored in a sealed container in a cool, ventilated, and dry indoor area. During transportation, it must be tightly sealed to prevent moisture, exposure to strong acids or alkalis, and contamination by rainwater or other impurities.
