3M™ VHB AFT 4614 is a high performance double coated acrylic foam product which possesses a good balance between shear peel and high tack adhesion. It has been designed to be suitable for a range of bonding applications which require a level of adhesion higher than standard double coated foam tapes.
Common Characteristics
The fast and easy to use permanent bonding method provides high strength and long-term durability. It offers design flexibility with its viscoelasticity and powerful ability to bond to a variety of surfaces. It is colourless making it ideal for bonding transparent materials or for applications where a coloured bond line is unacceptable.
