Application Information

Characteristics and Advantages

uYINK-A52 serves as a standard anti-foaming agent in most solvent-based coatings, with strong defoaming performance, particularly effective in non-polar systems. Its compatibility as a standard defoamer requires testing for its impact on varnish transparency and cratering. For systems requiring high transparency, our YINK-A51 is recommended.

uYINK-A52 inhibits foam formation during the stirring and application of printing inks. It rapidly breaks foam without affecting intercoat adhesion and performs well in solvent-free radiation-curable printing inks and overprint varnishes.

Recommended Applications

vPrinting inks and overprint varnishes

vIndustrial coatings

vAutomotive OEM coatings

vWood and furniture coatings

vArchitectural coatings

vAnticorrosive coatings

Recommended Dosage

0.1-0.8% based on the total formulation.

The above dosage is empirical; the optimal amount should be determined through a series of tests.
