Green Solutions For Substrate Wetting and Defoaming

In the modern world, companies simply cannot afford to ignore environmental issues. This sustainability trend is driven by society's changing values, with consumers demanding that industry act more responsibly, and governments around the world introducing increasingly strict legislation to ensure it does so. International coatings manufacturers are among the companies that have to comply with stricter environmental regulations, while at the same time improving product performance and meeting the requirements of consumers. VOC emissions are one of the most important formulation parameters in the coatings industry. VOCs participate in atmospheric photochemical processes. and are believed to contribute to the formation of ground-level ozone. For these reasons, regulatory limits have been set in many parts of the world to limit their content in paints and related products) Also, customers are increasingly looking for additives that have low or zero VOC content, but they are not prepared to compromise on performance, and demand the usual application level. Waterborne coatings are generally known to reduce the levels of VOCs, but to achieve satisfactory performance, formulators have to use an array of additives such as wetting agents, coalescents, rheology modifiers and defoamers.
