Product Description
Piccotac™ 8595 Hydrocarbon Resin is an aromatic-modified, aliphatic hydrocarbon resin developed for the adhesives industry. Its specific degree of modification and low molecular weight provides Piccotac™ 8595 Hydrocarbon Resin with excellent compatibility in SIS, SIS/SBS, SIBS, SIBS/SIS and SIBS/SBS block copolymers HMPSA systems, and EVA and APO based packaging adhesives. Piccotac™ 8595 is stabilized by the addition of 0.1% antioxidant. For more information about Piccotac™ 8595, part of our Piccotac™ product family, go to

Compatibility and Solubility
Compatible at all ratios, or in limited but practically useful proportions, with styrenic block copolymers such as SIS (styrene-isoprene-styrene) and SIBS (styrene-isoprene-butadiene-styrene) and styrenic block copolymer blends of SIS/SBS (styrene-isoprene-styrene / styrene-butadiene-styrene), SIBS/SIS and SIBS/SBS, natural rubber, EVA (ethylene-vinyl acetate) copolymers, APO (amorphous polyolefin), paraffin and microcrystalline waxes.

Soluble at all useful proportions in aliphatic, aromatic and chlorinated hydrocarbons, esters and ethers. Insoluble in alcohols, glycols and water.

Pastilles, in multiwall bags (50 lbs., 22.7 kg, net wt.), packaged on shrink-wrapped pallets of 50 bags each (2500 lbs, 1134 kg), from Eastman facilities and warehouses in Pennsylvania.


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.
