Changing Defoamers for a Changing Market

In an increasingly developing and environmentally conscious world, the demand for safer, greener products is on the rise. This demand has affected the coatings industry, calling for changes such as lower VOC resins and safer alternatives to what used to be considered traditional methods and materials. The industry has risen to the challenge to meet these new requirements, producing newer resin systems with excellent characteristics such as gloss and hide, but foaming issues remain a lingering problem in many of these newer materials and processes.

These newly formulated systems require newer, more efficient defoamers to aid in processing and application. In response, Elementis Specialties has recently come forward with four new products in order to combat continuously evolving foaming problems. These products include two emulsion based systems, a glycol silicone system, and a hybrid system, with each technology containing its own advantages. The glycol silicone provides gloss retention as well as excellent defoaming properties, and is recommended for use in surfactant heavy systems such as tinted high gloss bases. The hybrid system is a blend of different defoaming technologies in a single product—a great functional offset to over-performing competitors offering efficient foam control used in the flat to semi-gloss area. Lastly, the emulsion systems provide well rounded performance in multiple areas as well as wood coatings.


Ocean Tang graduated from Rutgers University in 2013 with a bachelor’s degree in chemistry. He joined Elementis Specialties in March of 2014 and has been working as a technical service chemist in the defoamer area since. Prior to entering the coatings industry, Ocean had experience interning at UMDNJ in immunological and biochemical labs, as well as working in chemical analysis for a short time.
