Product Information

LORD Chemlok® 234B (NW) adhesive is a general purpose covercoat adhesive designed for use over Chemlok 205 primer. This adhesive system will bond a wide variety of vulcanized or unvulcanized rubber compounds to primed metal or other rigid substrates. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

Chemlok 234B (NW) adhesive will bond compounds based on natural rubber (NR), polyisoprene (IR), styrene-butadiene (SBR), polybutadiene (BR), polychloroprene (CR), nitrile (NBR), butyl (IIR) and chlorosulfonated polyethylene (CSM).

Shelf Life

Shelf life is one year from date of shipment when stored in a well ventilated area at 21-27°C (70-80°F) in original, unopened container.

Features and Benefits

Versatile – when used in combination with Chemlok 205 primer, bonds a variety of cured and uncured elastomer compounds; flexible enough to bond uncured to cured, or cured to cured rubbers with the same or different compositions.
