A water-based ultra-low VOC polyurethane (PU) polymer coating technology, Lurapret N5396 & N5392 liq, was launched by producer of dyes and specialty chemicals Archroma Management LLC, Reinach/Switzerland, at the ITMA 2019 in Barcelona/Spain.
The coatings have been developed to provide textile manufacturers with an additional water-based option that delivers high performance to the coated fabrics of demanding applications, such as indoor and outdoor textiles, nonwovens and papers. Initially developed for the chemical bonding and coating for backpack and other industrial products, Lurapret N5396 & N5392 liq also improve the mechanical properties of the treated material such as their tensile strength and scratch resistance.
The new products will be the core of Archroma's Safe Seats system. The system, which combines the new technology with the company’s halogen-free Pekoflam STC p flame retardant, allows a halogen-free flame retardant coating system for synthetic leather upholstery to be created. In combination with Nuva N2155 & N4547 soil protection and release finishes, high standards in water-repellence and waterproofness can be achieved.
Lurapret N5396 & N5392 liq can be applied by impregnation, coating (paste or foam), and spray, and are compliant with the ZDHC and bluesign requirements.
