If you love the balanced performance of PUD-821H but need an eco-friendlier option, PUD-821F delivers—without missing a beat. This aliphatic polyurethane dispersion offers the same reliable film quality, flexibility, and durability as its predecessor, but with one major upgrade: it’s completely NMP-free.
With a solid content of 33±1%, PUD-821F forms consistent, durable coatings with excellent mechanical integrity. Though slightly lower in elongation than 821H, it still provides ample stretch for flexible substrates, ranging from 250–350%. Its tensile strength of 14.2 MPa and modulus of 6.1 MPa bring a stiffer, more defined structure to the film—perfect for applications that require a tougher touch without going brittle.
Where PUD-821F really shines is in its chemical resistance. Like 821H, it features excellent alkali and water resistance, making it a smart, cost-effective choice for coatings on fabric and leather that need to endure repeated wear and washing.
Whether you’re formulating for fashion, upholstery, or performance textiles, PUD-821F gives you the quality and performance you expect—without the environmental baggage. It’s the right choice when you need a cleaner polyurethane dispersion that still gets the job done.
So if you’re looking to go NMP-free without compromising on quality, PUD-821F is your go-to alternative.
