CONTRAM ST-1 - Description

CONTRAM ST-1 is a highly concentrated and purified industrial bactericide based on N,N-Methylenebismorpholine (CAS#: 5625-90-1). CONTRAM ST-1 is effective against both gram-negative and gram-positive bacteria. Since CONTRAM ST-1 has limited efficacy against fungi, the product should be used in combination with a fungicide. To inhibit the growth of bacteria in soluble oil and semi-synthetic metalworking fluids, the recommended addition level for CONTRAM ST-1 is 3% in concentrates designed for 20:1 dilution. At a 3% treat level, this results in a 1500ppm concentration in the diluted metalworking fluid. CONTRAM ST-1 might be added to the oil phase prior to addition of water when preparing a semi-synthetic formulation in order to maximize product efficacy and ensure long lasting performance.
