Water based PU coating

For water-based PU coating, it is possible to add Omnistab HN 130. Although HN 130 works well in reducing phenolic yellowing, it is more suitable for solvent-based coatings. but it still has the possibilities to reduce the dosage appropriately (eg. 0.2-0.5%), which helps improve its dispersion. The best solution is Omnistab AN 6133. It is a liquid antioxidant, and more likely to disperse in water-based coating. And it has the advantages of Eco-friendly, phenol free, low volatility and hydrolysis resistance, which more meet customer's requirement. The recommended dosage of AN 6133 is 0.3-1.0%
