Effects of Adhesive and Processing Parameters on Adhesive Bonding of Polycarbonate

Abstract:

The Weibull distribution was found to be quite useful in studying the effects of adhesive and processing parameters on adhesive bonding of polycarbonate. Adhesive selection is very important in satisfactorily bonding this polymer. Ethanol wipe and sanding as surface pretreatments of the polycarbonate appear to be equivalent. The humidity exposure of polycarbonate before and during bonding is briefly discussed. Surface exposure times SET of up to 30 days appear not to affect strength of either tested or aged specimens of urethane adhesive bonds. The lower-strength epoxy bonds aged 30 days at 49 C 120 F and 95 RH lose strength after the 30 day SET.
