Product Description
Tacolyn™ 5070 resin dispersion is an aqueous, 50% solids, solvent-free anionic aliphatic hydrocarbon dispersion prepared from a low molecular weight, aliphatic C5 hydrocarbon resin. It is recommended as a tackifier for isoprene rubber and natural rubber latex polymers used in tape applications. Tacolyn™ 5070 is ideal for low peel applications because it imparts peel strength in small increments relative to resination level. It exhibits good storage and mechanical stability and outstanding stability to acids. Tacolyn™ 5070 is also highly resistant to acids and alkalies.

Compatibility and Solubility
Compatible with natural rubber latex. When mixed with cationic substances, this dispersion may precipitate. When high alkaline or acidic additives are added to Tacolyn™ 5070, gross localized pH-variations should be avoided, as these can lead to destabilization and grit formation.

Packaging
Available in lined fiber drums (445 lbs/202 kg net wt.), disposable totes or tank trucks. Keep container closed to prevent formation of dried film on container walls. If dry filming occurs, filter product before use.

Storage
The useful life of this product can be affected by storage and handling conditions. This dispersion will remain within product specification limits for at least 243 days from date of manufacture from an Eastman production facility provided that storage conditions are observed. The recommended storage temperature range is 50°-100°F. This resin dispersion may be irreparably damaged if frozen. Accordingly, all shipments in cold climate areas are made in insulated or heated carriers. It is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.
