Freeze Sensitivity: Product freezes below 5°C; freeze-thaw cycles destabilize the product. Store above 5°C.
Cationic Product Incompatibility: Contact with cationic products causes coagulation (precipitation). Do not use in the same bath with cationic products.
Strong Acidic Catalysts: Strong acidic catalysts destabilize the product.
Pigmented Application Stirring: Continuous stirring is required to prevent pigment settling. Bath temperature must not exceed 35°C.
Arkophob® XLR liq Usage: Arkophob® XLR liq solutions must be used within 4 hours. Avoid long machine stoppage times.
Curing Time: Proper curing (170-175°C, 45 seconds) is essential for good washing and rubbing fastness.
pH Adjustment: When used with Fixapret® ECO liq c, adjust bath pH to 5.0 with acetic acid.
Storage: Store at 5°C to 30°C, protected from freezing, in original sealed packaging.
Application: Apply by pad method at room temperature. Control padding pick-up ratio.
Stirring: Ensure continuous stirring for pigmented applications. Keep bath temperature below 35°C.
Curing: Achieve optimum fastness values with curing at 170-175°C for 45 seconds.
Machine Downtime: Minimize machine stoppage times, especially when using Arkophob® XLR liq.
pH Control: Adjust pH to 5.0 when using with Fixapret® ECO liq c.
Safety: Use PPE (gloves, goggles).
