Spandex® might encounter some shade change due to specific gases in the atmosphere.
Use Orcocil GFM-S™ for Spandex® especially when used in blends with nylon to prevent gas-fade and yellowing. Orcocil GFM-S™ is used as a topical finish to prevent gas-fading especially on whites and narrow elastics. It is a resinous-type gas fade inhibitor for the prevention of gas fading of Acetate, Nylon, Polyester, and Spandex®. Orcocil GFM-S™ is compatible with numerous textile auxiliaries such as Poly Vinyl Acetate, optical brighteners, softeners, etc., although pre-dilution is recommended.

3-8 oz/gal. Orcocil GFM-S™ depending on degree of yellowing or hand desired.
