High-performance adhesive tape
3M™ VHB+™ 4941 is a conformable, very high-bond acrylic foam tape. Its added performance for bonding to plasticised vinyl is due to a specially formulated adhesive that resists plasticiser migration. In addition, this core adhesive composition makes the product well suited to many paints and primers. 3M™ VHB+™ 4941's principal advantages are that it provides a more uniform seal on irregular surfaces, and invisible bonds under a transparent surface it offers a more aesthetically pleasing bond. This product has been found to be particularly suitable for bonding wooden (primed), aluminium (anodised) and PVC Georgian glazing bars (muntin bars) to glazing units. The plasticiser resistant adhesive also allows for successful bonding of flexible PVC glazing bars.
