Eastman Olefin Resin Eastotac H

The Eastman Eastotac H series comprises Olefin Resin engineered for high-performance adhesives, coatings, and specialty formulations. Utilizing advanced hydrogenation technology, these resins achieve superior thermal stability (softening points up to 130°C) and water-white to low-color clarity (Gardner melt color ≤8), ensuring compatibility with UV-sensitive and aesthetic-critical applications.

Designed for versatile compatibility, the resins integrate seamlessly with SBS, SIS, EVA elastomers, and tackifiers, optimizing adhesion strength and processability in hot-melt adhesives, pressure-sensitive tapes, and automotive coatings.

Enhanced flow properties ensure stable processing in solvent-based or molten systems, while maintaining eco-friendly profiles.
