SIWO US Inc.’s paper specialty aliphatic polyurethane dispersions (PUDs) are engineered to meet the exacting demands of modern paper processing, packaging, and specialty coating industries. Our advanced aliphatic PUD formulations combine proven waterborne polyurethane expertise with targeted performance benefits such as enhanced longevity, improved strength, and environmental compliance. SIWO’s solutions help extend the service life of paper products while delivering functional enhancements that support industrial and commercial grade applications.
Waterborne polyurethane dispersions from SIWO US are built on aliphatic polymer backbones that deliver clarity, flexibility, and durability. Unlike traditional solvent-borne systems, waterborne dispersions reduce VOC emissions while maintaining high performance across mechanical and environmental conditions. These formulations are suitable for coatings where flexibility and durability are critical, particularly on fibrous and flexible substrates such as paper. Our paper specialty aliphatic PUDs provide balanced film formation, strong adhesion, and robust barrier properties that prevent premature degradation, enhancing overall paper product quality.
Aliphatic PUD coatings act as reinforcement layers that increase fold endurance and tear resistance in paper substrate structures. When applied in reinforcement systems, these dispersions form a cohesive, flexible film that supports fiber networks against mechanical stress and dynamic bending. Their ability to absorb stress without cracking or delaminating improves durability in high-performance packaging and industrial paper products. By enhancing internal strength and fiber interaction, SIWO aliphatic dispersions significantly reduce the risk of premature failure during converting and end-use.
SIWO’s specialty PUDs are ideal for high barrier coatings that protect paper products from moisture, oils, and other environmental contaminants. These coatings create a tight molecular film that blocks permeability, improving resistance to water vapor and liquid penetration without compromising surface feel or printability. Barrier coatings developed with our waterborne aliphatic polyurethane systems also support secondary functional layers such as sealants or laminating adhesives, creating multi-functional paper systems used in packaging, industrial liners, and high-end print products.
For thermal paper and specialty printing applications, SIWO’s dispersions can be tailored as low thermal paper resins that enable efficient heat transfer without sacrificing tensile integrity. These lightweight films enhance coating uniformity and thermal responsiveness, improving sensitivity and reaction accuracy for thermal print processes. In addition, waterborne aliphatic PUDs form low haze, clear coatings that preserve print contrast while improving surface durability in rapid heat cycling environments.
SIWO’s aliphatic polyurethane dispersions exhibit strong resistance to abrasion, moisture, and environmental aging due to their waterborne design. These coatings maintain flexibility over time, reducing cracking and edge-lift that can compromise longevity in folded or manipulated paper. (siwo-us.com)
Film integrity is central to reinforcement and barrier functions. SIWO PUDs form cohesive films with excellent tensile strength, flexibility, and adhesion, enhancing fold endurance and tear resistance even at thin film builds.
The hydrophobic segments of the aliphatic polyurethane networks limit water absorption and block moisture migration, creating effective coatings that protect against environmental degradation.
As waterborne systems, SIWO aliphatic PUDs deliver high performance without hazardous solvents, helping manufacturers meet regulatory goals for low emissions and safer workplace environments.

Sustainability & Lifecycle Value
SIWO’s waterborne aliphatic PUDs align with industry trends toward greener chemistry and higher-efficiency paper products. By replacing solvent-based resins with waterborne alternatives, manufacturers can reduce VOC emissions and post-use environmental impacts. In addition, enhanced durability from SIWO coatings reduces the need for recoating and minimizes material waste over the product lifecycle. Waterborne PUDs also enable safer processing and handling, supporting compliance with environmental and workplace safety standards.
