#  Chemlok® 8212 Adhesive 

### 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.
