New Low Foam Superwetters DynolTM 800 and Dynol 810 Surfactants
The application of waterborne coatings and inks on difficult-to-coat substrates, such as wood, plastics, films and poorly prepared metal surfaces, presents significant challenges to the coatings formulator. To maximize wetting and minimize defects like craters, fisheyes, orange peel and pinholes, the proper surfactant is needed to promote substrate wetting and minimize foam generation. Air Products developed Dynol 800 and Dynol 810 surfactants to meet the growing need for high performance surfactants.
Our Dynol 800 surfactant can provide a superior balance of properties compared to traditional fluorosurfactants and silicone surfactants, with exceptional performance in wood and plastic coatings. In a three-coat brush application of a model urethane-acrylic hybrid interior wood coating, this surfactant offers improved wetting plus superior flow, leveling and foam control compared to coatings containing silicone surfactants.
Air Products’ Dynol 810 surfactant, specifically designed for waterborne printing inks and overprint varnishes, is an excellent alternative for difficult-to-wet substrates requiring good flow and leveling under diverse application conditions. This surfactant offers superior wetting and printability while maintaining excellent foam control over traditional organic, silicone and fluoro-based surfactants when it’s used to print on film substrates such as oriented polypropylene or high-slip polyethylene.
Both of these new superwetters offer premium surface tension reduction, improved formulation compatibility and ease of incorporation without the addition of APEs, HAPs or VOCs. Let us help you wet those most difficult substrates while minimizing foam. For specific use and formulation guidance, call us at 800-345-3148 or 610-481-6799.
