Speciality Zipper | PFAS-FREE
Water Repellent Polyester Zipper
A PFAS-Free, Water Repellent Alternative
HydroFast Zipper ™
Our Hydrofast Zippers are processed using an innovative, PFAS-free and PCAS-free water repellent solvent to achieve water resistance without the use of TPU lamination.
Compared to TPU laminated zippers, Hydrofast Zipper offers significant advantages:
Much lighter weight and thinner, enhancing comfort and wearability in garments and bags
Breathable and flexible unlike stiff TPU coatings
Lower environmental impact with no hazardous chemicals
Cost-effective, reducing logistic expenses and import duties
Visually appealing without changing the zipper's look or feel
Hydrofast brings a high-performance sustainable solution, making water repellent zippers accessible to wider markets across apparel and accessories.
PFAS-Free Water Repellent Zipper
Use Case
By leveraging innovative chemistry and processes, our zipper technology offers superior wet weather protection and stain resistance compared to standard zippers, while remaining durable, breathable and recyclable. This makes it an ideal solution for outerwear, gear and apparel.
