SiwoPUD-MattPUD-1903

When it comes to achieving a truly soft feel with an inherent matte finish, SiwoPUD-MattPUD-1903 sets the standard. This aliphatic polyurethane dispersion based on polyether is designed for applications where both tactile sensation and low-gloss aesthetics are essential. Supplied as 32% in water, this milky white dispersion is NMP, NEP, and DMAC free, making it an environmentally responsible choice for next-generation coatings.

The performance of MattPUD-1903 is as impressive as its finish. With a non-volatile constituent of 32 ±1%, a pH range of 7.0–9.5, and a viscosity of 400–1500 mPa·s, it is highly stable and easy to process. It forms films with elongation between 700–800%, a tensile strength of 33.4 MPa, and an elasticity modulus (100%) of 2.8 MPa, striking an ideal balance between flexibility and durability. Even under demanding conditions, it offers non-yellowing performance and excellent hydrolysis resistance, ensuring longevity and visual consistency over time.

One of its standout qualities is its ultra-low gloss, achieving ≤0.5 gloss at 60º, which delivers a premium matte aesthetic without the need for additional matting agents. When combined with alkaline-soluble resins, MattPUD-1903 excels in print performance and enhances the soft-touch properties of coated surfaces. For applications that demand stronger chemical resistance, it can be crosslinked with aziridine crosslinker or water-dispersible polyisocyanate crosslinker.

Ideal for paper, leather, textiles, and specialty coatings, SiwoPUD-MattPUD-1903 offers a perfect solution for manufacturers seeking durable, eco-friendly, and luxurious finishes that enhance both the look and feel of their products. Proper storage in frost-free, tightly sealed containers at 5–38℃ ensures peak performance over its service life.

If your project calls for a soft, ultra-matte, and highly durable polyurethane coating, MattPUD-1903 is the go-to choice for premium surface finishing.
