Chemlok® 8212 Adhesive Where to Buy


Product Information

LORD Chemlok® 8212 adhesive is an aqueous (water-based) covercoat adhesive used to bond a variety of elastomers to primed metal during vulcanization. It is composed of a mixture of dispersed fillers, resins and latices in water-based medium.

Chemlok 8212 adhesive is recommended for spray and dip application over Chemlok 8008 or 8009 water-based primer. When used over the water-based primer, this adhesive system will also bond cold rolled steel, phosphatized steel, aluminum and other various substrates.

Shelf Life

Shelf life is six months from date of shipment when stored in a well ventilated area at 21-27°C (70-80°F) in original, unopened container. Do not freeze product.

Features and Benefits

Versatile - bonds a variety of natural and synthetic elastomers to primed metal, including NR, SBR and Butyl.

Process Compatible - works well in injection and transfer molding applications; provides excellent prebake resistance.

Environmentally Friendly - uses water for cleanup while adhesive is still wet, eliminating the need for significant solvent inventory.

Environmentally Resistant - provides excellent resistance to hostile environments including salt water and heat.

Easy to Use - ready to use directly out of the container without dilution; not prone to hard settling; easily redispersed.
