Chemlok® 253H adhesive is a high solids, one-coat adhesive that bonds rubber compounds to various metals including carbon and alloy steels, stainless steel, aluminum, magnesium, zinc, copper and copper alloys. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

Chemlok 253H adhesive is a non-chlorinated solvent adhesive that can be applied as a one- or two-coat system.

Features and Benefits:
• Convenient – requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.
• Non-Chlorinated Solvent System – suitable for solvent incineration, saving cost of recovery equipment.
• Environmentally Resistant – provides superior resistance to heat, oils and salt spray.

Elastomers:
• Natural rubber (NR)
• Polyisoprene (IR)
• Styrene-butadiene (SBR)
• Polybutadiene (BR)
• Polychloroprene (CR)
• Nitrile (NBR)
• Butyl (IIR)
• EPDM Polymers
• Chlorinated Polyethylene (CPE)
• Chlorosulfonated Polyethylene (CSM)

Shelf Life/Storage:
