IOTA245 wetting agent efficiently solves common issues including insufficient substrate wetting, poor leveling and coating craters in waterborne paint and ink formulations. Featuring good water solubility and slip property, it is compatible with most waterborne resin systems and serves as a versatile coating additive.



During the production and application of waterborne paints and inks, many formulators are confronted with tough challenges. After coating application, the liquid fails to wet substrates thoroughly, resulting in craters and pinholes on dry films. Finished coatings feel rough with poor surface smoothness. Uneven flow and leveling also lead to orange peel defects. These flaws ruin coating appearance and downgrade product quality. Rework raises production costs, which remains a widespread headache in waterborne formulation development. Proper wetting and leveling additives are essential to mitigate such problems.

IOTA245 wetting agent is a colorless to pale yellow liquid with active content above 99.8%, featuring high purity and low impurities. It delivers dual functions of substrate wetting and leveling. With favorable water solubility, it disperses easily in waterborne systems without complicated pre-dispersion steps for convenient dosing. Once incorporated into formulations, it reduces surface friction, enables uniform spreading of coatings on substrates, minimizes film defects such as craters, and endows coatings with smooth surface touch.

It covers a wide range of applications, suitable for waterborne industrial coatings, dip coatings, carpet adhesives, various adhesives, waterborne coatings, waterborne wood coatings, waterborne polyurethane, waterborne printing paste, waterborne varnish, waterborne acrylic resin, waterborne alkyd resin and more. It works well for spraying, dip coating and roll coating processes. In printing paste and waterborne varnish formulations, its slip feature optimizes surface feel. For industrial and wood coatings, it mainly improves substrate wetting and prevents crater formation.

When selecting additives, many formulators worry about poor compatibility between additives and resins, which may destabilize the whole system. IOTA245 wetting agent shows good compatibility with the above waterborne resins. Proper addition will not easily trigger separation or loss of gloss. During formulation trials, it is recommended to carry out lab tests with different dosages to confirm optimal loading before mass production.

In summary, IOTA245 wetting agent integrates wetting, leveling and slip functions to mitigate common film defects in waterborne coatings. It serves multiple industries including coatings, inks and adhesives. For formulators troubled by craters and bad leveling, this universal wetting and leveling additive is a promising candidate for formulation evaluation.
