Product Description
Piccotac™ 8090-E hydrocarbon resin is an aromatic-modified, aliphatic hydrocarbon resin developed for the adhesives industry. Its specific degree of modification provides Piccotac 8090-E with an excellent compatibility with solution and emulsion SBR, SBS, EVA, and many polar elastomers. Due to its low odor and very good thermostability, Piccotac 8090-E is suggested as tackifying resin for high quality hot melt and hot melt pressure sensitive adhesives. Piccotac 8090-E is stabilized by addition of antioxidant.

Compatibility and Solubility
Compatible at all ratios or in limited but practically useful proportions, with natural and synthetic rubbers, solution and emulsion SBR, EVA (ethylene-vinyl acetate) copolymers, SBS (styrene-butadiene-styrene), SIS (styrene-isoprene-styrene), and SEBS (styrene-ethylene/butylene-styrene) block copolymers block copolymers, APAO (amorphous poly-alpha-olefins), low molecular weight polyethylene, paraffin and microcrystalline waxes.
Soluble at all useful proportions in aliphatic, aromatic and chlorinated hydrocarbons, esters and ethers. Insoluble in alcohols, glycols and water.


Packaging
Piccotac™ 8090-E hydrocarbon resin is pastillated and packed in polyethylene bags of 20 kg net, and supplied on shrink wrapped pallets of 50 bags (1000 kg) each, or in big bags of 1000 kgs each, from Eastman facilities in the Netherlands and from warehouses located in Europe.

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.

Piccotac™ 8090-E hydrocarbon resin material will remain within product specification limits for a period of at least twelve months after shipment from Eastman''''s production facilities in the Netherlands, provided storage conditions outlined in this data sheet are observed. However, as we can neither anticipate the conditions under which the resin is processed nor the end use applications for which it is used, we recommend that the material be tested upon receipt.
