Kristalex™ F85 hydrocarbon resin is a water-clear, color-stable, low molecular weight, thermoplastic hydrocarbon polymer. Based on purified 8 - 9 carbon aromatic monomers, this resin is compatible with a wide variety of oils, waxes, alkyds, polymers and elastomers, and is soluble in many common organic solvents. It is indicated for use in plastics modification, adhesives, coatings, sealants and caulks. In EVA-based hot melt adhesives Kristalex™ F85 is compatible with EVA grades with up to 30% vinyl acetate and is useful in formulating low-color adhesives with good low temperature properties. In styrenic block copolymer based adhesives Kristalex™ F85 preferentially associates with the styrenic endblocks, producing lower melt viscosity without affecting tack and adhesion properties.

Compatibility and Solubility

Compatible at all ratios, or in limited but practically useful proportions, with a wide variety of materials such as SBR and Styrene based block copolymers, neoprene, nitrile, polybutadiene, acrylic polymers, chlorinated rubber, EVA resins (ethylenevinyl acetate copolymers), styrenated alkyds, vinylated alkyds, drying oil alkyds and rosin ester resins.

Soluble in aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, esters and ketones. Insoluble in alcohols and glycols.

Solubility Parameters, minimum 20% resin concentration. 6.9 - 10.0 in Class I solvents - weakly hydrogen-bonded; 6.7 - 12.6 in Class II solvents - moderately hydrogen-bonded; 6.9 - 10.7 in Class III solvents - strongly hydrogen-bonded.

Packaging & Availability

Packaging Information

Kristalex™ F85 Hydrocarbon Resin is pastillated and packed in polyethylene bags of 25 kg net, and supplied on shrink-wrapped pallets of 40 bags (1000 kg) each, from Eastman facilities in The Netherlands and from warehouses located in Europe.

Storage & Handling

+
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.

Kristalex™ F85 Hydrocarbon Resin material will remain within product specification limits, as mentioned under the heading "Product Specifications", for a period of at least twelve months after shipment from Eastman 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.
