Date : June 1998EPX Adhesive DP6104Directions for UsePlace the cartridge into the3M EPX Applicator and clipinto position.Remove the resealable cap.Expel a small quantity ofadhesive and ensure bothcomponents flow freely.Attach correct mixer nozzle(this should have 20 ormore elements).Dispense the adhesive asrequired.When finished either leavethe nozzle in place andstore, or remove the nozzle,wipe clean the tip, andreplace cap.To re-start after storageremove the old nozzle withcured adhesive and re-fit anew nozzle, or remove thecap and fit a new nozzle.Surface Preparation:The degree of surfacepreparation depends on thebond strength required andthe environment likely to beencountered by the bondedstructure.For most applicationssolvent wiping with 3MVHB Surface Cleaner,followed by abrasion with3M Scotchbrite 7447,followed by a further solventwipe until clean, will givegood performance (exceptfor acetal, polyethylene andpolypropylene and someother low surface energymaterials). The sameprocess will also give goodadhesion to metal surfaces.Where humid environmentsare likely to be encounteredwe recommend additionalpriming with 3M Scotch-Weld 1945B/A for metalsurfaces.Clean UpClean-Up:Excess uncured adhesivecan be removed with thefollowing products:3M VHB Surface Cleaner(mild alcohol basedcleaner)3M Scotch-Grip SolventNo2.
