Curvalam is an optically clear Cast PVC overlaminate for our range of CFOWV perforated window films. Curvalam is highly recommended for use over PromoVue and AutoVue perforated window films. Curvalam will prevent apertures clogging with dirt and grime as well as protect your print. Curvalam will also assist cleaning the surface. Curvalam carries exceptional clear vision properties, even when the angle of the windscreen is acute.
