CX-205A

CX-205A is a non-silicone defoamer, suitable for solvent-based coatings, inks and thermosetting resin systems. It can also be used to eliminate bubbles generated during production, application and substrate wetting without affecting interlayer adhesion.

Product advantages

  • It has an extremely strong defoaming ability, which can solve the problems that are difficult to defoam in the system, inhibit the introduction of bubbles during stirring, and help release tiny bubbles from the coating.

  • It can solve the problem of stirring bubbles in matte powder and zinc powder, and help remove bubbles during the construction of porous substrates.

  • It can solve the problem of stirring bubbles in matte powder and zinc powder, and help remove bubbles during the construction of porous substrates.

  • It will not affect the interlayer adhesion and is especially suitable for defoaming primers.

Proposed dosage
It is recommended for two-component PU systems, amino baking varnish systems, nitrocellulose immersion coating systems, acid-cured amino systems, coil coatings, etc. The dosage varies according to different usage systems. It is recommended to add 0.05% to 0.5% of the total amount. Please test the optimal dosage.
Application area
Recommended: Industrial coatings, automotive coatings, architectural coatings, wood and furniture coatings;

Processing instructions
For the best performance, the defoamer should be added to the grinding material before grinding.
If added in the later stage, there must be a sufficiently high shear force to ensure the good dispersion of the defoamer and prevent craters.
Storage and transportation
This product should be transported and stored as a hazardous chemical. It should be placed in a cool and well-ventilated area, with the container kept tightly sealed and away from heat and fire sources. When the temperature is below 5℃, stratification and turbidity may occur. Heat until clear before use. Shelf life: 36 months.
Packing specification
25KG/glue barrel,190KG/metal bucket.
