Q1: What are the primary application areas for Chan Chem L-2887?
A: Chan Chem L-2887 is widely used in high-performance waterborne coatings for flexible substrates, including synthetic leather, textile finishes, and soft-touch automotive interior trim. Its excellent film-forming ability and low-temperature coalescence make it especially suitable for heat-sensitive materials.
Q2: How does L-2887 compare to solvent-based polyurethane resins in terms of performance and processing?
A: L-2887 delivers comparable mechanical strength, abrasion resistance, and elasticity to many solvent-based alternatives while offering significantly lower VOC content and improved workplace safety. It requires no organic solvents for dilution and can be applied using standard aqueous coating equipment, though optimal film formation may benefit from controlled humidity and gentle thermal curing.
Q3: Can L-2887 be blended with other waterborne polymers or additives?
A: Yes, L-2887 demonstrates good compatibility with common waterborne acrylics, styrene-acrylic dispersions, and crosslinkers such as aziridine or carbodiimide types. Compatibility testing under intended formulation conditions—including pH, ionic strength, and shear history—is recommended prior to full-scale integration.
Q4: What is the typical shelf life and recommended storage condition?
A: When stored unopened in a cool, dry place away from direct sunlight and freezing temperatures, L-2887 typically maintains stability for up to 12 months. After opening, it should be kept tightly sealed and used within 6 weeks to ensure consistent viscosity and dispersion integrity.
