In Switzerland, specialty chemical company Archroma has unveiled a biobased, durable water repellent finish for outerwear and apparel fabrics that delivers rain and stain protection with a soft and comfortable feel.

Dubbed PHOBOTEX® NTR-50 LIQ, the coating can be used on synthetic fibers and blends, making it suitable for a wide range of applications including apparel, outdoor wear, and home textiles. The finish achieves its water repellence without undesirable effects such as yellowing and chalk marking.

It is also based on 50% renewable carbon content, is free from per- and polyfluoroalkyl substances and formaldehyde, and does not require crosslinkers.
