Chemlok® 8212 Adhesive Where to Buy


Product Information

Chemlok® 8212 adhesive is a water-based covercoat adhesive that bonds a variety of elastomers to primed metal. It is composed of a mixture of dispersed fillers, resins and latices in aqueous medium.

Chemlok 8212 adhesive is recommended for spray application over Chemlok 8008 or 8009 water-based primer or Chemlok 205 solvent-based primer. Dip application methods can also be used depending on process conditions.

Elastomers:
Natural Rubber (NR)
Styrene-butadiene (SBR)
Polychloroprene (CR)
Nitrile (NBR)
Butyl (IIR)

Shelf Life

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

Features and Benefits

Versatile – when used in combination with recommended Chemlok primer, bonds a variety of natural and synthetic elastomers to primed metal; adhesive system also bonds cold rolled steel, phosphatized steel, aluminum and other various substrates.

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

Environmentally Preferred – 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.
