When the stakes are high and the heat is higher, PUD-1691 rises to the occasion. This aliphatic polyurethane dispersion is engineered to perform where conventional coatings break down—delivering exceptional hardness and thermal stability, even under extreme conditions.
Formulated with a solid content of 40±1%, PUD-1691 creates a durable, high-density film that can withstand the intense demands of high-temperature processes. It’s the go-to choice for applications such as bonding aramid fibers in body armor—where strength, heat resistance, and long-term performance are non-negotiable. Whether you’re working with advanced composites or engaging in precision transfer coatings, this PUD provides a stable and secure bond without compromising film integrity.
Though specific mechanical properties like elongation, tensile strength, and modulus are not listed, its real-world performance speaks volumes: high hardness and excellent heat resistance are its standout traits. This makes PUD-1691 particularly well-suited for use in technical textiles, protective gear, and engineered substrates where thermal exposure and material compatibility are critical.
Yes, PUD-1691 contains NMP, but for specialized industrial applications that demand superior resistance and strength at elevated temperatures, it’s a top contender. From defense tech to industrial manufacturing, it delivers the toughness required to perform without fail.
If your coating needs to handle the heat—literally—PUD-1691 is your solution.
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.
