It’s also versatile! Shell-Tech Free is the ideal DWR for a wide variety of end products, including medical wear & PPE, workwear, athleisure apparel, hats, gloves, socks, tarpaulins, boat covers, awnings, tents, indoor & outdoor furniture, carpeting, filters, footwear, skiwear, and more.

All this, plus an exceptional sustainability profile. Shell-Tech Free is water-based, highly biodegradable, recyclable, doesn’t contain VOC’s (volatile organic compounds) or emit dangerous off-gasses and has been manufactured using solar energy in a bluesign-accredited facility.

Shell-Tech Free is stable in the finish bath and resists the roller build-up commonly found with many other competing fluorine-free DWRs.

Shell-Tech Free can be applied at lower finish add-on levels compared to competing fluorine-free repellents. This produces repellent fabrics with significantly reduced mark-off issues. The lower finish add-on also reduces color change and hand stiffening.

Shell-Tech Free produces exceptional repellency properties on a variety of synthetic and natural fiber textiles including stretch fiber blends and has a very wide processing window. This DWR tolerates non-uniform fabric preparation and doesn’t require high temperatures for application. Lower temperature curing preserves fabric properties such as color, hand and dimensional stability. Shell-Tech Free can also be applied successfully over fabrics that have received sub-optimal cleaning. While many fluorine-free DWR products demand scrupulous pre-cleaning before finishing to achieve high repellency, Shell-Tech Free can tolerate less rigorous cleaning and still perform at a high level.
