The Eastman Olefin Resin Butvar series offers thermoplastic solutions engineered for high-performance coatings and adhesives across industries. These resins combine exceptional optical clarity with robust mechanical properties, including impact resistance, flexibility, and adhesion to diverse substrates such as metals, plastics, and composites. Their hydroxyl-rich structure enables crosslinking with thermoset systems, enhancing chemical and environmental durability in demanding applications
Ideal for automotive safety glass interlayers, the series ensures laminated glass integrity while maintaining transparency under stress. In industrial coatings, they provide corrosion protection and weather resistance for metal surfaces, wire enamels, and architectural components.
High Clarity: Produces transparent films for visually appealing applications.
Impact Resistance: Retains flexibility even in low-temperature conditions.
Chemical Stability: Resistant to oils and alkalis for long-lasting performance.
Multi-Substrate Adhesion: Ensures strong bonding with glass, metals, and plastics.
Automotive Refinish: Ideal for spot repairs and topcoat applications.
Safety Glass Interlayers: Suitable for windshields and architectural glass laminates.
Industrial Coatings: Provides anti-corrosion and wear-resistant protection.
Packaging Adhesives: Used in laminating transparent packaging materials.
