| Sales Grade | Isocyanate/Polyol Type | Type | Solid Content ( % ) | OH Content (%, Solvent Free) | NMP | Characteristics and Applications |
|---|---|---|---|---|---|---|
| OH-PUD-1938 | Aliphatic/ Polycarbonate | Carbonate | 35±1 | 2.5 | Free | It has higher hydroxyl content, high hardness, and excellent abrasion resistance, weather resistance and hydrolysis resistance. It can be used alone or mixed with water-based hydroxy polyacrylic resin and water-based polyester etc. It mainly be used in 2-pack systems with water-dispersible polyisocyanate crosslinker or be combined with an amino resin to formulate water-dilutable stoving coatings and primers which cure at approx. 120-130℃. |
| OH-PUD-1530 | Aliphatic/ Polycarbonate | Carbonate | 40±1 | 1.2 | NMP | Containing lower hydroxyl content, excellent weather resistance and good hydrolysis resistance, lower hardness, good elasticity. It can be used alone or in combination with other aqueous resin. Water-dispersible polyisocyanate crosslinker can be used for room temperature curing, or amino resin used for high temperature curing. |
| OH-PUD-1930 | Aliphatic/ Polyester | Ester | 40±1 | 1.5 | Free | Containing lower hydroxyl content, lower hardness, and good elasticity. It can be used alone or in combination with other aqueous resin. Water-dispersible polyisocyanate crosslinker can be used for room temperature curing, or amino resin used for high temperature curing. |
| OH-PUD-1538 | Aliphatic/ Polyester | Ester | 35±1 | 2.5 | Free | The film has excellent hardness, excellent water resistance and excellent resistance to alcohol after adding water-dispersible polyisocyanate crosslinker. Amino resin can also be used for high temperature curing. It can be used for water-based wood coating, water-based floor paint and water-based industrial paint , etc. |
| OH-PUD-903 | Aliphatic/ Polyester | Ester | 33±1 | 1.2 | Free | It contains lower hydroxyl content. The film has excellent hardness, good water resistance and good resistance to alcohol after adding water-dispersible polyisocyanate crosslinker.

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.
