Q1: What is the primary function of Eastman Eastek 1000 in coating and ink formulations?
A: Eastek 1000 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 1000 compatible with other common water-based resins and additives?
A: Yes, Eastek 1000 demonstrates broad compatibility with acrylic dispersions, polyurethane dispersions, and many water-soluble thickeners, defoamers, and coalescing agents. Compatibility should always be verified in the final formulation through stability testing under intended storage and processing conditions.
Q3: How does Eastek 1000 perform in terms of drying and film formation at ambient conditions?
A: As a self-crosslinking polyester dispersion, Eastek 1000 forms continuous, flexible films at room temperature with minimal coalescent requirement. Film formation is typically efficient across a range of humidity levels, though optimal performance is achieved when applied in well-ventilated environments with moderate air flow.
Q4: Can Eastek 1000 be used in food-contact compliant coatings?
A: Eastek 1000 is not pre-certified for direct food contact applications. Formulators intending to use it in such systems must conduct full regulatory evaluation—including migration testing and compliance verification—based on regional requirements and final formulation composition.
