Chemlok 218T Adhesive
One-coat adhesive for bonding polyurethane elastomers
Chemlok 218T is a single-coat adhesive designed to bond various polyurethane elastomers, including castable, millable, thermoplastic (TPU), and Hytrel TPE, to metal and other rigid substrates. Its non-chlorinated solvent formulation offers a convenient, cost-effective solution for bonding applications, eliminating the need for primers and minimizing application costs. The adhesive's non-pigmented nature prevents color leaching into the bonded elastomer, ensuring consistent aesthetics.
