Efka® RM 1920



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. Sagging of thick films on vertical surfaces is effectively prevented whilst the working and flow properties are also generally improved. Pigment settling is also substantially reduced.
