Q1: What are the primary application areas for Chan Chem L-2815?
A: Chan Chem L-2815 is widely used in waterborne coatings for flexible substrates—including synthetic leather, textiles, and automotive interior trim—where excellent film flexibility, abrasion resistance, and low-VOC performance are required.
Q2: Is L-2815 compatible with other waterborne resins or additives?
A: Yes, L-2815 demonstrates good compatibility with common waterborne acrylics, polyacrylates, and crosslinkers such as aziridines or carbodiimides. Compatibility testing under specific formulation conditions is recommended prior to full-scale use.
Q3: How should L-2815 be stored and handled to maintain stability?
A: Store in tightly sealed containers at temperatures between 5–35 °C, away from freezing and direct sunlight. Avoid prolonged exposure to high humidity or strong oxidizing agents. Stir gently before use if phase separation occurs after extended storage.
Q4: Does L-2815 require a co-solvent for optimal film formation?
A: While L-2815 is formulated for good film-forming capability without added co-solvents, small amounts of low-VOC co-solvents (e.g., dipropylene glycol methyl ether) may be used to adjust drying behavior or improve substrate wetting in demanding applications.
