When your coating needs to hold strong and flex under pressure—U-57 is your answer. This aliphatic/polyester polyurethane dispersion is engineered for applications that demand durability, elasticity, and precision under heat. From fabric coatings to thermal transfer systems and elastomer substrate bonding, U-57 delivers high-end performance where standard coatings fall short.
With a solid content of 50±1%, U-57 stands out as a high-solids formulation, offering more build and less water for efficient film formation. Its elongation reaches 110%, giving it just enough stretch to stay flexible without compromising structure. Combined with its heat-activated performance at elevated temperatures, this dispersion shines in processes where bonding strength improves with applied heat—think laminates, textile composites, or any situation where pressure meets precision.
The result? A coating that doesn’t just sit on the surface—it fuses with it.
Yes, it contains NMP, but its exceptional bonding ability on flexible or heat-reactive materials makes it an industry go-to when other systems fail to hold up under heat and stress.
Whether you’re building next-gen apparel components, transferring graphics under pressure, or reinforcing elastomer assemblies, U-57 is built to handle the heat—literally.
So if you’re looking for a polyurethane dispersion with excellent elasticity, high tensile strength, and thermally activated bonding power, U-57 should be at the top of your spec sheet.
High-Quality Waterborne Polyurethanes That You Can Trust
SIWO US Inc. is a leading Water Based Polyurethane manufacturer specializing in innovative and eco-friendly solutions. With over 25 years in the game, we’re all about crafting top-notch water based PU dispersions for a myriad of industries. From textiles to automotive interiors, our products are designed to meet diverse needs.
PUD resins, or Polyurethane Dispersions, are water-based polymers that serve as the backbone for high-performance coatings and adhesives. They offer stellar durability, flexibility, and resistance to chemicals and abrasion. Plus, being water-based means they’re kinder to the environment compared to their solvent-based counterparts.
Great question! Water based PU is a game-changer. It delivers comparable, if not superior, performance in terms of durability and resistance. The real kicker? It’s got lower VOC emissions, making it a greener choice that doesn’t skimp on quality.
Far from it! While we do supply top-tier waterborne polyurethanes, we pride ourselves on being an R&D powerhouse. We’re constantly pushing the envelope to develop innovative solutions tailored to our clients’ unique needs. Think of us as your Polyurethane Material Supplier and innovation partner rolled into one.
