600R PLASTIC CEMENT

Product Description

Normac 600R plastic cement is a two component, room temperature curing, urethane dissolved in an acetone/toluene blend of solvents.  Addition of the proportioned Normac R Hardener (cross-linking agent) accelerates cure and improved adhesive strength.

Application
For best adhesion, roughen up the substrate with stiff bristled, rotating wire brush on an electric drill of 1400 RPM or less or slow speed disc sander with an aluminum oxide sanding disc of 36 grit or higher.  In some cases Normac 600R will bond successfully without surface preparation which can only be determined through test trials.

Thoroughly mix the appropriate amount of Normac R Hardener to the cement.  This mixture will give the applicator 4-6 hours pot life before cross-linking is completed.  Apply a brush coat on each surface to be bonded and let dry until tacky.  Adhere both surfaces and stitch down or apply pressure.  The maximum bond strength will develop to its optimum in 2-3 days, however, initial bond strengths will be sufficiently high after 3-4 hours for light service.  Should the surfaces of contact become dry, the cement may become reactivated and full strength bonds can be obtained by applying heat (60-70oC) to previous adhered substrates.  This will of course depend on their respective thickness.  Trials if possible, are recommended before production to determine the suitability of this compound with individual materials and to determine the preferred method of application.
