CONTRAM ST-1 is a highly concentrated industrial bactericide based on tetrahydrooxazines.
Owing to CONTRAM ST-1's good solubility this preserving agent is suitable for oily as well as aqueous systems.
CONTRAM ST-1 is effective against gram-negative and gram positive bacterias.

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.
Applications of CONTRAM ST-1:
CONTRAM ST-1 is successfully applied for the preservation, mineral oil containing, water miscible coolants.
For water based fluids based on a SOE-type we recommend to combine CONTRAM ST-1 with the emulsifier package LUBRIZOL 5375 and for a semisynthetic metalworking fluid to combine with emulsifier package LUBRIZOL 5683.
Compared to hexahydrotriazines and oxazolidines, CONTRAM ST-1 is more stable in metalworking concentrates.
CONTRAM ST-1 should be used at an addition level of 2 – 6% in a concentrate and at 0.3% in finished cutting fluid user dilutions, in order to have a concentration of 1,000 to 1,500 ppm of the active.
In order to get an additional effeciency against fungies we recommend using in combination with our CONTRAM J 20 or CONTRAM FKK.

Applications of CONTRAM ST-1:
Metalworking fluids
Features of CONTRAM ST-1:
Very stable and purified bactericide for metalworking concentrates with balanced oil and water solubility
In the EU this biocidal substance is already authorized under the Biocidal Products Regulation (BPR) for use in PT6 and PT13, and this Biocidal Product CONTRAM ST-1 is in the authorization process as a biocidal Product for use in PT13 for concentrate and tank side.
In Germany its use is limited to Export Only products
CONTRAM ST-1 is also registered in the United States under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) for use in metalworking concentrates.
The Environmental Protection Agency (EPA) registration number is 52484-3.
Metal working fluid concentrates containing CONTRAM ST-1 are therefor allowed for Import into the US.
Shelf Life of CONTRAM ST-1:
At least 12 months in original sealed containers.
CONTRAM ST-1 should be stored in steel or plastic containers, dry and at room temperature.
CONTRAM ST-1 industrial biocide is an extremely effective antibacterial compound for use in aqueous metalworking fluids.
Unlike competitive products, which are designed for other uses and may require the addition of non-ionics and more expensive emulsifiers, CONTRAM ST-I was developed specifically for use in metalworking fluids.
The EPA approved CONTRAM ST-1 product for use in the US is exceptionally stable in metalworking fluid concentrates and does not disrupt the balance of the emulsifier system.
The product also demonstrates long lasting efficacy in diluted emulsions; it lasts throughout the majority of the life of the metalworking fluid, which means longer drain intervals, reduced maintenance costs, and much less work tank side.
