Parker Lord has been known for its vulcanizing adhesives (hot bonders) for decades. Now they are offering a new, one-part system cold-bonding (CB) adhesive that is easier and safer to use than existing alternatives.
Existing CB adhesives, for bonding vulcanized rubber-to-metal, utilize carcinogenic substances or restricted VOCs, whereas Parker Lord’s Chemlok® CB adhesives are free of trichloroethylene (TCE) and contain lower levels of volatile organic compounds (VOCs).
Chemlok® CB 150 Adhesive is a one-part system which bonds vulcanized rubber-to-rubber and rubber-to-metal at ambient (room) temperatures. This innovative adhesive system does not require dumping and mixing and has an unlimited pot life for less waste and longer open times.
Chemlok® CB150 was designed for use with natural rubber, chloroprene, neoprene, and similar compounds. Many vulcanized rubber sheets, especially those with hard-to-bond halogenated and bromated compounds, use a polar bonding layer to improve bonding to the substrate. When used with a Chemlok® primer, Chemlok® CB150 also adheres to metal.
If the adhesive becomes too dry, Chemlok® CB150 can be rejuvenated for up to 24 hours after application by soaking a rag in xylene and wiping it onto the surface of the substrate. (Be sure to allow adequate time for the xylene to dry off before mating.) As long as the bond line is not stressed, most assets can be moved immediately after lining.
Curing occurs between 24 and 72 hours. Full strength is reached in seven days.
Chemlok® CB102CS is a VOC-exempt, HAPs-compliant, solvent-based surface treatment for use on various vulcanized and thermoplastic polymeric materials. It chemically alters the surface of the rubber, making it more receptive to bonding. Chemlok® CB102CS is used in conjunction with a broad range of Parker Lord adhesives, including epoxy and urethane adhesives, for bonding cured rubber.
Chemlok® CB 100 A/B Adhesive is a two-part system which bonds which bonds vulcanized rubber-to-rubber and rubber-to-metal at ambient (room) temperatures.
