Ser-ad FS 531 Anorganic manganese complex Condea Servo Drier / Siccative Coatings >> Waterborne NUODEX Driers and Catalysts SER-AD FS 531 Cobalt-free drier GENERAL INFORMATION SER-AD FS 531 is a cobalt-free drier catalyst special developed for water borne air-drying paint systems. APPLICATION AND PROPERTIES SER-AD FS 531 is based on an anorganic manganese complex. In those systems where Cobalt is not allowed SER-AD FS 531 is a very good alternative. The product can be used in combination with Calcium and Zirconium metal soaps. SER-AD FS 531 is emulsifiable in water. Feature -> Consequence Complex structure -> improved hardness -> improved drying properties DOSAGE SER-AD FS 531 should be applied at a concentration of 1.0-5.0 %, calculated on the total amount of paint. In pigmented paints where SER-AD FS 531 is used as post-additive, we recommend to make a 50% master batch of SER-AD FS 531 in water, to avoid formation of agglomerates Cobalt-free drier catalyst special developed for water borne air-drying paint systems.
