Product Description
Eastotac™ H-115L is a hydrogenated hydrocarbon resin, having a ring and ball softening point of 115°C and a molten Gardner color of 2. Eastotac H-115L has excellent compatibility with APAO (amorphous poly-alpha-olefins), metallocene-catalyzed polyolefins, as well as the midblock of SIS (styrene-isoprene-styrene), and SEBS (styrene-ethylene/butylene-styrene) block copolymers. Eastotac H-115L resin is used in numerous adhesive and sealant applications.

Packaging
The standard package for Eastotac™ H series resins is a 50-pound (22.7-kg) multiwall paper bag. Samples (1 kilogram) are available for evaluation.

Storage
Due to the thermoplastic behavior, pastillated and flaked resins may fuse, block or lump. This can be accelerated under any of the following conditions: 1) above ambient temperature 2) prolonged storage 3) pressure, e.g., stacking pallets, or a combination of these conditions. This is particularly applicable for low softening point resin grades. In order to maintain the flake or pastille shape, we therefore recommend storing the material in a temperature-controlled area; be careful with stacking material or applying pressure and preventing prolonged storage. It should be noted that lumping does not have a negative impact on the product specifications. Due to the nature of the product, claims regarding lumping cannot be accepted.

Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on the solubility of the resin in organic solvents or on its compatibility with polymers. Accordingly, it is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.

Based on stability testing conducted on comparable resin samples, and available information from past experience, when stored in the original unopened container in an enclosed area under storage conditions outlined in this data sheet, protected from moisture, extreme temperatures and contamination, this product is estimated to continue to meet applicable sales specifications for 3 years from the date of manufacture. The exact useful life of this product can be affected by such things as storage and handling conditions and the conditions relating to past experiences may not be representative of your specific product storage and handling conditions. As a user of this product, you should be guided by your own determination that your use of the product is safe, lawful, and technically suitable in your intended applications. Refer to the Safety Data Sheet for available health, safety, storage and handling information.
