Q1: What is the primary function of Eastman Eastek 1400 in coating formulations?
A: Eastek 1400 functions as a film-forming polymer dispersion that enhances adhesion, flexibility, and chemical resistance in waterborne industrial coatings—particularly where improved substrate wetting and low-temperature film coalescence are required.
Q2: Is Eastek 1400 compatible with common waterborne acrylic or vinyl acetate-based dispersions?
A: Yes, Eastek 1400 is designed for broad compatibility with many waterborne polymer systems, including acrylics and VAE dispersions. Compatibility should be confirmed through small-scale formulation trials to assess stability, viscosity behavior, and final film properties.
Q3: How does Eastek 1400 contribute to performance in can and coil coatings?
A: In can and coil coating applications, Eastek 1400 supports excellent metal adhesion, corrosion inhibition synergy with pigments and inhibitors, and good resistance to sterilization and cleaning agents—making it suitable for demanding food-contact and industrial metal packaging environments.
Q4: What are the recommended storage conditions for Eastek 1400?
A: Store in original, tightly sealed containers at temperatures between 5 °C and 30 °C. Avoid freezing and prolonged exposure to temperatures above 35 °C. Protect from direct sunlight and ensure adequate ventilation in storage areas.
