SiwoPUD®-919F

Glossy, Tough, and Ready for the Real World

Characteristics:

Aqueous, aliphatic polyurethane dispersion based on poly(ester+carbonate).

Supplied as:

35% in water

Storage:

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

Application:

Looking for a coating that does it all—shine, strength, and serious resistance? PUD-919F brings the best of both worlds with high hardness and impressive flexibility, making it a versatile go-to for everything from wood finishes to film coatings, rubber applications, and even acrylic emulsion modification.

This aliphatic polyurethane dispersion comes in with a solid content of 35±1%, offering excellent film-forming capabilities without overloading your formula. With a tensile strength of 18.2 MPa, elongation at 290%, and a 100% modulus of 8.4 MPa, PUD-919F packs in just the right mix of durability and stretch—strong enough to protect, yet flexible enough to adapt.

One of the standout features? That high-gloss finish. It delivers a sharp, clear look that elevates the surface it’s applied to—perfect for wood grains, smooth plastics, or detailed rubber textures. But the shine’s not just for show—PUD-919F also brings the muscle: excellent water and abrasion resistance, hydrolysis resistance, and standout performance against NaOH and other chemicals that usually eat lesser coatings alive.

Unlike its sibling PUD-920F, this one has better toughness and flexibility, making it more forgiving on impact while still holding a firm finish. Oh, and it’s NMP-free, so you’re getting pro-level performance without the harsh extras.

Whether you’re fine-tuning your wood coating lineup or upgrading your plastic films, PUD-919F is the all-rounder that handles the heat and keeps things looking sharp.
