RESUMO

Tests show that trichloro- and tetrachloro-4-(methylsulfonyl) pyridines have a wide spectrum of activity against microorganisms causing deterioration in industrial systems. They are particularly active as fungistats and are more effective against gram-positive than against gram-negative bacteria. Their fungistatic activity and persistence have led to outstanding performance as mildewcides in exterior paints. In addition, we report the performance of these compounds as preservatives in the following products: asphalt, calking compositions, joint cements, paper, plastics, soluble oils (cutting fluid emulsions), and textiles.
