Product description

Dureflex A4700 is a self-priming, polyether based, low modulus aliphatic thermoplastic polyurethane film/sheet product.

Applications

Dureflex A4700 was developed as part of a series of optical grade adhesive films. Dureflex A4700 was specifically developed for the lamination of optically transparent glass-clad polycarbonate. Dureflex A4700 is also used in acrylic composites CAB and other compatible thermoplastics.Dureflex A4700 can be supplied from 15 to 50 mils (0.38 to 1.27 mm) with a specially developed film finish to allow for evacuation of trapped air during press or autoclave bonding. Dureflex A4700 is supplied with a protective polyethylene interleaf to prevent film-to-film roll blocking, and should be incorporated where a "primerless" lamination is required. As with any product, use of Dureflex A4700 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
