The product is not sensitive to frost
The product maintains its entire enzymatic activity for
at least 6 months if stored at temperatures up to 30oC.
Avoid longer storage times at temperatures above 30oC.

DILUTION

VINALASE PK-400 can be diluted with cold water in any ratio.

APPLICATION

Reactive dyestuffs often being very sensitive to peroxide, it is necessary to destroy
the remaining peroxide of the prebleaching process through several cold and warm
rinsing baths or through addition of suitable peroxide killers.
VINALASE PK CONC allows for the catalytic remaining peroxide after bleaching
to be converted to inactive oxygen and water.
The following advantages are achieved through the application Of VINALSE PK CONC
Low water consumption
Time saving
No ecological waste water pollution
VINALASE PK CONC is an enzyme for decomposing H2O2 in oxygen and water.
Just like all enzymes which are used for textile procedures, the catalase requires
basic conditions for optimum efficiency.
pH range: pH 4.0 – 9.0
Treatment temperature: 20 – 60oC
Process Time : 10 – 30 min

RECIPE
PROPOSALS

This results in the following procedure sequence:
H2O2 Bleach
Overflow rinsing
Fresh bath
0.05 – 0.10 g/l VINALASE PK CONC
10 15 min. at 20 – 60oC
Remaining peroxide control, e.g. with Merck test stripes Dyeing in the same bath
