SiwoPUD®-OH-1530

The Weatherproof Workhorse with a Soft Side

Characteristics:

Aqueous, aliphatic hydroxy-functional polyurethane dispersion based on special polyester.

Supplied as:

40% in water

Storage:

The dispersion should be stored in a frost-free place in tightly sealed containers. It contains no preservative.

Application:

When your coating needs to flex and endure, OH-PUD-1530 rises to the challenge. This aliphatic/polycarbonate polyurethane dispersion strikes a rare balance: it’s soft and elastic, yet loaded with the resilience to handle harsh environments.

With a solid content of 40±1%, OH-PUD-1530 forms films that hold up beautifully without adding bulk. The secret to its toughness? A low hydroxyl content that enhances weather resistance and hydrolysis resistance, meaning it performs exceptionally well under UV exposure and in humid or wet conditions.

Despite its durability, it doesn’t compromise on feel. This PUD offers lower hardness and good elasticity, making it ideal for substrates or products that demand a supple, flexible finish without sacrificing longevity. Whether you’re working on leather goods, protective coatings, or specialty textiles, it adapts to your needs—effortlessly.

It’s also incredibly versatile in formulation. OH-PUD-1530 can be used alone or in combination with other aqueous resins, giving formulators the freedom to dial in specific performance profiles. For curing, it plays well with both worlds: pair it with a water-dispersible polyisocyanate crosslinker for room temperature curing, or opt for an amino resin for high temperature curing. Either way, you’re looking at a coating that’s built to last.

Yes, it contains NMP, but its performance and flexibility make it a go-to for demanding applications where both endurance and softness matter.

If you’re searching for a polyurethane dispersion that weathers the elements without losing its flex—OH-PUD-1530 should be in your formulation toolbox.
