Arcseam DR 450 Pail and Drum End Sealing Compound
A high-deposit, water-based elastomer sealing compound for pail and drum ends that are lined on large-diameter equipment and cured at ambient temperature. It builds a thick, coherent bead in one pass without cracking as the water leaves and reaches handling strength within a working shift.

1. Product description
A high-deposit compound for pail and drum ends that are lined and left to cure at ambient temperature, where oven drying a large end is impractical. It is formulated to build a thick, coherent bead in one pass without cracking as the water leaves, and to reach handling strength within a working shift so the ends can be stacked. It carries the highest dry deposit weight in the range, matched to the large curl volume and the heavier gauge of industrial ends.
2. Features
- Ambient cure, for large ends where oven drying is impractical
- Builds a thick, coherent bead in one pass without shrinkage cracking
- Handling strength typically within one working shift, so ends can be stacked
- Deposit weight at the top of the Arcseam range, matched to large curl volumes and heavy gauge
3. Recommended uses
Lacquered and unlacquered tinplate and steel pail and drum ends for industrial packaging, lined on nozzle or flow lining equipment and cured without an oven.
Substrates. Lacquered and unlacquered tinplate and steel pail and drum ends.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Water-based elastomer dispersion, high-solids ambient-cure grade | Formulation |
| Appearance | Smooth, homogeneous viscous fluid dispersion, free of lumps and skin | customer or supplier protocol |
| Volatile organic compound content | typically below 50 g/l, water is the principal carrier | ISO 11890-2 |
| Non-volatile matter (solids) | 54 to 62 % by weight | ISO 3251 |
| Viscosity, rotational, at 23 degrees Celsius | 8,000 to 15,000 mPa.s, spindle and speed as stated on the Certificate of Analysis | ISO 2555 |
| pH as supplied | 8.0 to 11.0 | ISO 976 |
| Density at 20 degrees Celsius | 1.10 to 1.30 g/cm3 | ISO 2811-1 |
| Sieve residue (grit) on a 100 micrometre mesh | below 0.05 % by weight | ISO 4576 |
| Dry deposit weight per end | about 300 to 1,500 mg per end, set by end diameter, gauge and measured curl void | In-house, gravimetric, end weighed before and after lining and drying |
| Compression set of the dried compound | 25 to 40 % | In-house, on cast test pieces, adapted from ASTM D395 Method B |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Nozzle or flow lining on large-diameter equipment, laying the full bead in one pass. |
| End preparation | Curl clean, dry and free of forming oil, lubricant residue and loose dirt. Confirm adhesion on the lacquered or unlacquered end stock in use, and on unlacquered steel confirm that no flash rust forms under the bead during the ambient dry. |
| Preparation and dilution | Supplied ready for use and not thinned as a matter of routine. Stir slowly to redisperse any settlement, avoid high-shear stirring that aerates the compound, and agitate gently in the day tank so solids stay uniform across the shift. |
| Dry deposit weight | About 300 to 1,500 mg per end, set to fill the measured curl void; check-weigh ends at intervals through the shift. |
| Cure schedule | Ambient cure with air movement around the ends. Handling strength is typically reached within one working shift; allow longer at low temperature or high humidity before stacking, and do not let lined ends freeze before the bead has dried. |
| Next step | Stack once handling strength is reached and confirm there is no blocking or face-to-face transfer. Qualification is by seam teardown and leak testing on the customer's own line. |
Process. Nozzle or flow lining on large-diameter equipment, ambient cure.
6. Storage and handling
Store in the original closed containers at 5 to 35 degrees Celsius, protect from frost and keep out of direct sun; stir slowly before use. Shelf life is stated on the label and the Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
