This product has been found to be particularly suitable for bonding wooden(primed), aluminum (anodized), and PVCGeorgian glazing bars(muntin bars) to glazing units.
The plasticizer-resistant adhesive also allows for the successful bonding of flexible PVC glazing bars.
The conformable nature of the acrylic foam core allows for good 'wetting out of the adhesive to the glass surface thus providing good adhesive-to-surface contact.
Also, good contact eliminates unsightly air bubbles. Primers might be appropriate when bonding such systems.
It has also been found excellent when bonding to relatively irregular surfaces such as grained wood. (Care must be taken to provide a good unified surface through priming.)
