CONTRAM ST-2

CONTRAM ST-2

Description
CONTRAM ST-2 is a highly concentrated industrial bactericide based on tetra hydro oxazines. 
Due to its good solubility, this preserving agent (CONTRAM ST-2) is suitable for oilbased and water-based systems.
CONTRAM ST-2 is effective against gram-negative and grampositive bacteria.

CONTRAM ST-2 is a highly concentrated industrial bactericide based on tetra hydro oxazines. 
Due to its good solubility, CONTRAM ST-2 is suitable for oilbased and water-based systems.
CONTRAM ST-2 is effective against gram-negative and grampositive bacteria. 

Application
CONTRAM ST-2 has been used successfully to preserve oil-based and water-based metalworking fluids.
Compared to hexahydrotriazines and oxazolidines, CONTRAM ST-2 is more stable in metalworking concentrates.
The recommended addition level for CONTRAM ST-2 is 1 - 3% in the concentrate and 0.15% in the end use dilution.
CONTRAM ST-2 is not compatible with acids and oxidizing agents.

Shelf Life
At least 12 months in original sealed containers. 
The product should be stored in steel or plastic containers, dry and at room temperature. 

NOTE
If CONTRAM ST-2 is stored at ambient temperaturebelow 4ºC for longer time, the product might solidify.
The solidification will be removed at room temperature automatically or faster by slight heating of the product to 30 - 50ºC in a suitable heat chamber.
The quality and the composition of the product after thawing is unchanged.
