The latest generation in ultra-durable, fluorine-free water repellence

Shell-Tech Free is an outstanding DWR
that will fit your brand.

Bolger and O’Hearn is proud to introduce an advanced fluorine-free durable water repellent that provides the same repellency and wash durability as a quality C-6, but with significantly less environmental impact.

Outstanding Performance

A breakthrough technology, Shell-Tech Free has been engineered to maintain water and stain repellency through 50 or more launderings as well as multiple dry cleanings. In many cases, water repellency will last the life of a treated article. At the same time, Shell-Tech Free will not change or interfere with an article’s natural hand, drape, breathability or comfort.

Widespread Protection

Fabrics finished with Shell-Tech Free are also resistant to stains from soda, wine, sports drinks, mud, fruit juices and syrup

Endless Applications

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.

Advanced Sustainability

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 provides:

• Freedom from fluorocarbons • Freedom from processing issues
• Freedom from performance limitations

Shell-Tech Free is easy to apply at the mill.

The latest generation in ultra-durable, fluorine-free water repellence Bolger and O’Hearn is proud to introduce an advanced, premium-performance, fluorine-free durable water repellent that provides the same repellency, wash durability, and runnability as a quality C-6. The result is an outstanding DWR that is easy to apply at the mill.

Excellent Runnability

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

Low Mark-Off

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.

Robust Processing

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.
