General
EFKA® RM 1920 is a particularly finely ground additive used to impart a thixotropic effect to paints, printing inks and other coatings. The incorporation of EFKA® RM 1920 ensures a strong thixotropic effect in non-aqueous coatings. It can be also used in most non-aqueous coatings both with and without solvents. The lower the polarity of the coating, the better is its performance.
