REX 897 SF can be easily diluted in cold water. It is advisable to check the pH of the solution and eventually acidify.
REX 897 SF: 40 – 100 g / L
MORBIDOL 639: 30 – 60 g / L
Bath temperature: 20 ° – 40 ° C
Bath absorption: 60 – 80%
Drying: 120 ° C
Polymerization: 50 seconds at 140 ° C
30 seconds at 150 ° C
Do not exceed 150 ° C during curing, to avoid yellowing.
Always check the acidity of the bath, alkaline residues tend to produce yellowing.

Removing the REX 897 SF from the fabric:
Hydrochloric acid conc .: 2-3 g / L or Citric acid conc .: 8-10 g / L
Bath temperature: 50 ° C Bath temperature: 80 ° C
Time: 20 minutes. Time: 20 minutes.
De-acid treatment :
Sodium Carbonate: 1 g / L
SEQUESTRANTE 441: 1-2 g / L
Bath temperature: 50 ° C
