Rakoll® 4660

1 of 13 products in this brand

Rakoll® 4660 is a workhorse, universal reactive hot melt adhesive for wrapping a wide variety of standard-thickness interior foils. Rakoll®4660 was specifically designed for profile wrapping. It has high green strength and excellent melt flow properties, enabling fast line speeds. Open time can be extended by increasing application temperatures. Rakoll®4660 is a single-component, fully reactive hot melt adhesive that crosslinks through a chemical reaction with moisture found in the surrounding air and substrates to produce a thermoset adhesive.

Safety & Health

Environmental Recommendation: This product cannot be disposed directly in the sewers. Even though the product has a more environmental-friendly formulation, there are many chemicals in a PVAc dispersion that cannot be considered to have a neutral impact in the environment.
Safety Information: Use only in equipment intended for reactive hot melts. Use with local exhaust ventilation to remove vapors anywhere heated product is exposed to air including adhesive un-loaders, pre-melters, and application areas. Local exhaust ventilation may be required to maintain exposures at safe levels.

Storage & Handling

Storage Condition: To ensure maximum stability, product should be stored in the original closed container in a clean and dry interior location capable of maintaining a constant temperature between 50°F and 90°F.
Shelf Life: 9 months
