Compatibility and Solubility
Light color and color stability; heat resistance; excellent hot tack and fast set; and wide compatibility.
Compatible at all ratios, or in limited but practically useful proportions, with natural and synthetic rubbers, polyolefins, paraffin and microcrystalline waxes, and low-VA EVA resins (ethylene-vinyl acetate copolymers).
Soluble in aliphatic, aromatic and chlorinated hydrocarbons and methyl isobutyl ketone (MIBK). Insoluble in glycols, lower alcohols and water.
Solubility Parameters, 20% resin concentration. 6,8-9,7 in Class I solvents - weakly hydrogen-bonded; 6,7-9,8 in Class II solvents - moderately hydrogen-bonded; 6,8-9,5 in Class III solvents - strongly hydrogen bonded.
Piccotac™ 1100-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, from Eastman facilities in The Netherlands and from warehouses located in Europe.
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™ 1100-E 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.
