Orco Sunguard NC-3™ is an ultraviolet(UV) absorber that significantly improves the lightfastness of disperse-dyed polyester fabrics and yarns particularly in the automotive upholstery and floor coverings industries. Orco Sunguard NC-3™ is characterized by having extremely micronized particles in dispersion and is especially suitable for package dye applications. Orco Sunguard NC-3™3 is designed to prevent particle coagulation in the dye bath and redeposition on the dyeing equipment due to excellent dispersion stability and high exhaustive performance at high temperatures.
|Appearance||white milky emulsion|
|Composition||anionic nitrogen compound|
|Solubility||Dissolves in cold water|
|pH||8 for a 5% solution|
Not affected by a reduction clearing process after dyeing.
- Polyester fibers
- Continuous dyeing
- Package dying
Orco Sunguard NC-3™ is normally used for high-temperature batch exhaustion processes in conjunction with dye. The optimum usage level depends on the nature of the polyester fiber, depth of shade, and lightfastness requirements. The initial recommendation is 2% on weight of fabric.
