PU 2123 RHV

PU 2123 RHV by PT. Dover Chemical is a high-performance polyurethane resin known for its repeating –NHCOO structural units, delivering excellent performance. It is specially formulated for solvent-based white gravure printing inks and can also be used for colored inks.

• It has an aliphatic structure that provides excellent UV stability and anti-yellowing properties.
• It offers exceptional anti-yellowing performance, crucial for maintaining the brightness and purity of white inks.
• It provides excellent re-solubility and pigment dispersion for smooth, consistent color performance.
• It offers heat resistance, making it suitable for boiling and retort lamination processes.
• Its key attributes include a toluene-free composition that ensures safety and regulatory compliance.
• PU 2123 RHV requires the addition of a curing agent in the printing process when used for anti-retorting laminating inks.
• It significantly enhances durability, adhesion, and film-forming properties.
• It provides excellent adhesion to corona-treated PET film without requiring an adhesion promoter, while for BOPP, PE, and nylon films, the addition of an adhesion promoter is recommended.
• It has demonstrated good compatibility with various resins, showing strong affinity and wettability with pigments and dyes, good compatibility with resins such as VC/VAC and NC, and solubility in esters, ketones, and aromatic solvents.
• It is perfectly suited for food packaging applications.
• It is compatible with both one-component and two-component systems, meeting the specific demands of ink formulations.
• It has a shelf life of 1 year when stored in its original, unopened container.
