CONTRAM ST-1/50

CONTRAM ST-1/50

CONTRAM ST-1/50 is a highly concentrated industrial bactericide based on tetrahydrooxazines. 
Owing to its good solubility this preserving agent (CONTRAM ST-1/50) is suitable for oily as well as aqueous systems.
CONTRAM ST-1/50 is effective against gram-negative and gram positive bacterias.

Applications:

CONTRAM ST-1/50 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-1/50 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-1/50 is more stable in metalworking concentrates.
CONTRAM ST-1/50 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.

Other remarkable features:
- Low odour
- Low formaldehyde content
- Helps in the corrosion protection
- Very stable molecule
- Good compatibility and solubility
- Very good performance
- CONTRAM ST-1/50 can be used in fluids with pH of 3 to 12.

CONTRAM ST-1/50 is not compatible with acids and oxidizing agents.

Compared to hexahydrotriazines and oxazolidines, CONTRAM ST-1/50 is more stable in metalworking concentrates. 
CONTRAM ST-1/50 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.
