Bio-surfactants are a promising alternative to chemical surfactants in the development of eco-friendly and high-performance coatings due to their bio-degradability, low toxicity, renewable feedstocks, and enhanced performance in various aspects of coatings formulations.
Anti-foam products allow controlling the presence of unwanted foam in different processes, including the manufacture and application of paints. A new range of mineral oil-free anti-foams have been designed, which are not harmful to humans or the environment due to their low or no toxicity, and include enhanced bio-degradability of the raw materials.
This second article in our four-part series about additives discusses foam control agents, including defoamers, anti-foams and air release agents (deaerators), and some things to consider to help your formulation be both efficient and persistent.
DOWSIL™ 211S additive is a low-cyclic, ultra-high molecular weight silicone delivered in a waterborne system that enhances mar resistance, slip and block resistance performance, enabling more durable, longer-lasting wood coatings.
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.
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.
