HDK pyrogenic silica can help you optimize your coating and printing ink formulas in many ways. Even small amounts of HDK in your total formulation can give your coating a competitive edge in delivering the crucial properties your customers require. Minor loadings offer your coatings flow control and ease of application. In liquid coatings and inks, HDK prevents hard settling and provides good flow during application, well balanced leveling and anti-sag properties. The proper rheology of your formulas is critical to your customers’ satisfaction and HDK is a valuable tool for making this happen. HDK is a key component in powder coatings and can optimize flow in loadings of less than one percent.
