Q1: What are the primary application areas for Chan Chem L-2994?
A: Chan Chem L-2994 is widely used in waterborne industrial coatings, including flexible packaging laminating adhesives, textile and leather finishing systems, and protective topcoats for wood and metal substrates where low VOC content and good film integrity are required.
Q2: How does L-2994 compare to solvent-based polyurethane resins in terms of performance?
A: L-2994 delivers comparable film hardness, flexibility, and chemical resistance to many solvent-based alternatives, while offering significantly reduced environmental impact and improved workplace safety due to its waterborne nature and absence of aromatic solvents.
Q3: Can L-2994 be blended with other waterborne polymers such as acrylics or PUDs?
A: Yes, L-2994 exhibits good compatibility with many common waterborne acrylic dispersions and other polyurethane dispersions, enabling formulators to tailor film properties like gloss, mar resistance, and adhesion. Compatibility testing under actual formulation conditions is recommended prior to scale-up.
Q4: What is the typical shelf life and recommended storage conditions?
A: When stored unopened in a cool, dry place away from direct sunlight and freezing temperatures, L-2994 maintains optimal performance for up to 12 months. Avoid prolonged exposure to temperatures above 40 °C or repeated freeze-thaw cycles.
