SiwoPUD®-EC-100

In the world of high-performance coatings and adhesives, choosing the right crosslinker can make or break your formulation. SiwoPUD-EC-100 is engineered for demanding applications where consistency, low gloss, and long-term durability are key. This hydrophilic, aliphatic polyisocyanate is supplied at 100% non-volatile content, giving formulators maximum active material with zero fillers or solvents—just pure performance.

Unlike conventional crosslinkers, SiwoPUD-EC-100 is nonionic, making it broadly compatible with nonionic waterborne systems and reducing interference in delicate formulations. It features an NCO content of 19.0±1%, ensuring strong reactivity and reliable crosslinking with polyurethane dispersions, acrylic emulsions, and other hydroxyl-functional materials. Its low monomeric diisocyanate content (≤0.2%) means it meets safety and regulatory standards without compromising performance.

With a transparent appearance and viscosity ranging from 2000–4000 mPa·s, SiwoPUD-EC-100 is easy to work with and offers excellent mixing and film formation properties. Its density of 1.09 (d₄₂₀) makes it ideal for fine-tuning formulation weight and flow behavior in coatings, adhesives, and pastes. It is especially effective in water-based adhesives, printing pastes, and low-gloss coatings, where long-term performance and chemical resistance are a must.

SiwoPUD-EC-100 is best stored in tightly sealed containers, away from direct sunlight and frost, to preserve its reactivity and shelf life. For precise formulation work, it can be diluted using propylene glycol methyl ether acetate (PMA) or dipropylene glycol dimethyl ether (DMM)—both excellent carriers that maintain system stability.

For formulators seeking a reliable, high-purity polyisocyanate for water-based applications will find that SiwoPUD-EC-100 delivers on performance, compatibility, and quality.
