Chemlok® 238 (NW) adhesive is a covercoat adhesive used to bond a variety of non-polar elastomers to themselves or to Chemlok 205 primed metals and other rigid substrates. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.
Features and Benefits:
• Versatile – bonds non-polar rubber compounds based on butyl and EPDM; flexible enough to bond uncured to cured systems, as well as cured elastomers to cured elastomers with similiar compositions.
• Easy to Apply – applies easily by brush, dip, roll coat or spray methods.
Elastomers:
• Natural rubber (NR)
• Polyisoprene (IR)
• Styrene-butadiene (SBR)
• Polybutadiene (BR)
• Polychloroprene (CR)
• Nitrile (NBR)
• Butyl (IIR)
• Chlorosulfonated Polyethylene (CSM)
• EPDM Polymers
Shelf Life/Storage:
Shelf life is one year 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.
To help prevent the formation of a gel-like consistency, store Chemlok 238 (NW) adhesive above 21°C (70°F). If a gel-like consistency does develop, heat adhesive to temperature above 38°C (100°F) and mix the adhesive with a high speed agitator until it returns to a homogeneous liquid.
