Packaging & Availability
Packaged in aluminum-kraft-bags of 25 kg net, and supplied on shrink-wrapped pallets of 28 bags each.
Storage & Handling
Because of the extremely large surface area, flaked forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and /or could have an adverse effect on solubility in organic solvents. It is strongly recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first. Recommended storage is in original packaging, dry, free from contamination, below 30°C.
Flaked forms of low to medium-softening point resins may fuse, block, or lump:
(1) during hot-weather months,
(2) if stored near steam pipes or other sources of heat, and
(3) upon prolonged storage and compression.
Poly-Pale™ Partially Dimerized Rosin shelf-life for bag packaging is 18 months from production date; and the shelf-life of drum packaging is 18 months from production date, provided recommended storage conditions are observed.
