Cationic Incompatibility: Dicrylan PHR is an anionic product; contact with cationic products causes coagulation (precipitation). Do not use in the same bath with cationic products.
Freeze Sensitivity: Product is sensitive to freezing; do not store below 5°C.
Formaldehyde-Free: Product is formaldehyde-free; suitable for environmentally friendly applications.
Heat Treatment: Proper heat treatment is essential for optimum durability.
Preparation: Clean and dry the textile surface thoroughly before application.
Mixing: Mix with water or solvents according to manufacturer instructions.
Application: Select the appropriate method (brush, spray, dip, pad, foam).
Drying: Allow sufficient time for complete drying.
Heat Treatment: Apply heat treatment at recommended temperature and time.
Pretrial: Pre-trials are recommended for each specific application.
