Fast-Acting, Long Lasting
3M Fastbond Insulation Adhesive 49 is a long-time member of 3M?s portfolio of go-to, everyday-use adhesives considered by many to be necessary at the factory.
We designed 3M Fastbond Insulation Adhesive 49 to have an aggressive tack that offers a high initial grab as well as sufficient open time to position materials properly. High-solids content supports its low soak-in property, giving you ample time to align your insulation properly. This attribute also provides higher coverage than competing adhesives. The combination of fast tack, strong bond and clean appearance make it ideal for projects of all kinds.
