Defoamers that contain a molecular defoaming component as part of their composition show an ability to defoam more efficiently than their non-molecular defoaming-containing counterparts.

Ashland Specialty Ingredients, a business unit of Ashland Inc., is helping paint manufacturers meet the growing demands of the coatings industry with an expanding line of additive ingredients, research and support.

A fluorosilicone additive for defect-free foam control in solventborne and radiation-curable coatings

BYK-1640 is a polymer-based, VOC- and silicone-free defoamer for aqueous systems, which is also suitable for some applications that come into direct contact with food.

With this information, new foam-control additives are envisioned, enabling formulators to create the next generation of compliant coatings.

 A solvent-free, high-performance defoaming additive, Troykyd®D209W offers excellent functionality in a broad range of aqueous systems. 

FOAM BLAST® 4213 is an organo-modified silicone/synthetic antifoam product, while FOAM BLAST 4149 is a synthetic block copolymer composition developed as a non-silicone alternative.

Additives belong to a broad and diffuse category of key components in a coating formulation. The following is a brief description of many coating additives, along with some examples.

New products are being developed to meet the challenge of delivering low- and zero-VOC offerings, including specialty resins, coalescents/plasticizers, water-based and energy curable colorants, foam control and silicone products.
