Q1: What is the primary function of Eastman Eastek 1200 in coating and ink formulations?
A: Eastek 1200 functions as a film-forming polymer dispersion that enhances adhesion, flexibility, and surface durability in waterborne systems. It is commonly used to improve substrate bonding—especially on low-surface-energy plastics—and contributes to cohesive strength without compromising colloidal stability.
Q2: Is Eastek 1200 compatible with common waterborne acrylic or vinyl acetate-based emulsions?
A: Yes, Eastek 1200 is formulated for compatibility with a broad range of waterborne polymer emulsions, including acrylics and vinyl acetate copolymers. Compatibility should be verified in the final formulation through standard stability testing—including freeze-thaw, high-shear mixing, and storage evaluation—due to sensitivity to pH and ionic environment.
Q3: How does Eastek 1200 contribute to improving scratch resistance in dried films?
A: The polyester backbone and dispersed particle morphology of Eastek 1200 promote inter-particle coalescence and microstructural reinforcement during film formation. This results in improved hardness and resistance to light abrasion, particularly when combined with appropriate crosslinkers or post-cure treatments.
Q4: Can Eastek 1200 be used in food-contact compliant coatings?
A: Eastek 1200 is not pre-approved for direct food-contact applications. Formulators seeking regulatory compliance must conduct full migration and toxicological assessments aligned with applicable regional requirements, and verify suitability through third-party testing of the final cured film.
