FRX Polymers Inc. has announced the development of Nofia W2000 EX water-based dispersions for use in the production of low volatile organic compound (VOC) water-based textile coatings.

Coated textiles are utilized in various markets including automotive, aerospace, agricultural, industrial, healthcare, sports, and defense.

They deliver a range of superior properties including flame retardancy (FR), waterproofing and antimicrobial performance. In the last few years, water-based coatings have grown at a double-digit rate in the textile arena because of their ability to reduce air pollution and exposure to solvents used in solvent-based coatings. An unmet need in water-based coatings has been the ability to offer flame retardancy with a robust halogen-free solution, FRX says.

Nofia W2000 EX Dispersion – currently available for qualification trials – is transparent and has a 60 percent solid content and less than a 400-nanometer particle size. It is compatible with various water-based polymers including polyurethane dispersions used in textile coatings and synthetic leather applications, FRX says, and when added to PUD coatings, Nofia W2000 EX forms a fully transparent film with low haze and soft touch and feel.

The company says in halogen-free tents/tarps and fireproof clothing, Nofia W2000 EX Dispersion does not alter the coating to be seamlessly welded and passes all high-water pressure resistance tests as well as the jungle humidity test. The resulting products pass flame-retardant tests such as CPAI-84 (Canvas Products Association International). Nofia W2000 EX-based coatings also meet ASTM 6413 (vertical burn test for flame resistance of textiles).

In automotive synthetic leathers, Nofia W2000 EX-based coatings meet relevant automotive fire safety standards as well as new total VOC and fogging standards established by major global automotive suppliers as well as the new Chinese GB/T 27630-201X standard, FRX says, and in home furnishings, Nofia W2000 EX provides a halogen-free flame-retardant solution for synthetic leathers used in home furniture, meeting BS 5852 Crib 5 standards while maintaining good touch and feel.
