SARTOMER: Water-Based PUDs
A new line of UV-curable water-based polyurethane dispersions (PUDs) is available from this company. Reportedly developed to be free of solvents, surfactants and tin catalysts, CN9500 and CN9501 can provide enhanced formulation latitude. Both products are supplied at approximately 40% solids content and are compatible with other water-based coatings.
CN9500 and CN9501 reportedly contribute excellent coatings properties after water removal and UV curing, including good flow and leveling and a low minimum film formation temperature (MFFT). Both are dry to the touch after water removal. They can create a warm appearance on wood, are non-yellowing and are easily matted to a low-gloss finish.
CN9500 exhibits balanced flexibility and hardness, while CN9501 has exceptional hardness and abrasion resistance without brittleness. A shared resistance to water, stain and chemicals makes these PUDs applicable for coatings and adhesives.
