WB Fixer / Crosslinker
Water-based fixer and crosslinker is a reactive polyisocyanate or aziridine-based additive that chemically crosslinks the acrylic or PUD binder polymer chains during the curing cycle, dramatically improving washfastness, chemical resistance, and bond strength to the fabric substrate. Without crosslinking, many water-based inks exhibit inadequate washfastness, particularly on synthetic substrates. Addition rates of 3–8% and a minimum dwell time after addition ensure complete integration before printing begins.
Key Applications
- Improving washfastness of WB inks on cotton, polyester, and nylon
- Achieving commercial-grade durability on water-based print programs
- Crosslinking WB discharge inks for improved rub and wash resistance
- Essential addition for WB ink printing on non-absorbent synthetic substrates
Frequently Bought Together
WB Thickener
Water-based thickener is a rheology modifier — typically an associative urethane or acrylic alkali-swellable emulsion — that increases the viscosity and body of water-based ink systems to achieve the correct print paste consistency for the application and mesh count in use.
Screen PrintingWB Binder
Water-based binder is a concentrated acrylic or polyurethane polymer emulsion used to increase the binder-to-pigment ratio in water-based ink formulations, improving film strength, adhesion, and washfastness, particularly in heavily pigmented or discharge-activated systems.
Screen PrintingWB Softener
Water-based softener additive is a non-ionic emulsified silicone or fatty acid ester compound blended into water-based ink formulations to reduce the stiffness of the cured print film and improve the overall hand feel of the finished printed garment.
