Q1: What are the primary application areas for Chan Chem L-2813?
A: Chan Chem L-2813 is widely used in water-based coatings and inks for flexible packaging, paper lamination, and textile finishing—where film clarity, flexibility, and good adhesion to low-surface-energy substrates are required.
Q2: Is L-2813 compatible with other waterborne resins or additives?
A: Yes, L-2813 demonstrates good compatibility with common waterborne acrylics, styrene-acrylic emulsions, and selected crosslinkers such as aziridine or carbodiimide types—though compatibility testing under actual formulation conditions is recommended before full-scale use.
Q3: How should L-2813 be stored and handled to maintain stability?
A: Store in tightly sealed containers at temperatures between 5 °C and 30 °C, away from freezing conditions and direct sunlight. Avoid prolonged exposure to high humidity or contamination with incompatible solvents or metal ions, which may affect colloidal stability.
Q4: Does L-2813 require post-crosslinking for optimal performance?
A: While L-2813 forms functional films upon ambient drying, enhanced chemical resistance, heat resistance, and mechanical durability are typically achieved through thermal curing or addition of suitable crosslinkers—depending on end-use requirements.
