Ultra Light-Weld 9-20790 is solvent free. Lasting bonds form in seconds to both flexible and rigid substrates. Bond strength on polycarbonate and PVC usually exceed the strength of those substrates. DYMAX 9-20790 is highly thixotropic and ideal for applications where the material needs to retain its profile prior to curing.

Dispensing the Adhesive

This material may be dispensed with a variety of automatic bench-top syringe applicators or other equipment as required. Direct questions relating to dispensing and curing systems for specific applications, should be referred to the dymax applications engineering at (860) 482-1010.
