SiwoPUD®-U-JZ20

Built to Bond—Fast, Strong, and Heat-Ready

Characteristics:

It is an aqueous anionic polyurethane dispersion based on polyester. It is a raw material for formulation of heat-activated adhesives.

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:

When you need fast results and even faster adhesion, U-JZ20 delivers. This aliphatic/polyester polyurethane dispersion brings speed, strength, and thermal activation into one high-performance package. Designed for demanding industrial applications, U-JZ20 outpaces conventional dispersions like U-9091, thanks to its faster crystallization rate and stronger initial adhesion—giving you faster bonding without sacrificing performance.

With a solid content of 35±1%, U-JZ20 forms a consistent, durable film that holds up under stress and temperature. While its elongation measures at a controlled 125%, it shines in areas where stretch isn’t the priority—but holding power is. Its film boasts high strength, strong substrate adhesion, and reliable heat-activation performance at high temperature, making it an ideal choice for laminated composites, automotive interiors, footwear adhesives, and industrial laminates.

Best of all? It’s NMP-free, offering a safer and more eco-conscious solution that meets stringent regulatory and environmental standards. If you’re transitioning away from solvent-heavy or slower-setting PUDs, U-JZ20 provides a smart, sustainable upgrade—without compromising curing speed or bond quality.

In applications where thermal reactivation, tight hold, and efficiency matter most, U-JZ20 becomes your go-to polyurethane dispersion. It’s made for modern manufacturing processes where timing and durability are non-negotiable.
