HSL Flatting agent for solvent-based coating The wetting property and fine anti piping are improved by modifying the organic silicone component and reducing interfacial force of coating. The surface slipping, anti fish tail and adhesion performance increased too. Furthermore, the sensitivity of air particle and mist reduce. The avoidance Benard whirlpool can help to control loosing color of coating. The series includes:HSL-303¡¢HSL-305¡¢HSL-306. In addition,we also produce polyamide wax solvent anti-settling agent,dispersing agent for water based coatings and inks,water based antifoaming agent and water-based thickening agent.
