Michem Guard 349 and Michem Guard 350 from Michelman are wax dispersions used for imparting a matting effect to most aqueous coatings and varnishes. The coatings give water-based inks the performance properties of solvent-based systems, without the environmental hazards. They also enhance properties such as blocking and abrasion, water repellency, and scratch and mar resistance. Both are solvent-free and are designed to highlight the positive properties of large particle sized wax and minimize unnecessary interaction from dispersing agents.
