3M™ SMC/Fiberglass Repair Adhesives are two-part urethanes or two-part epoxies used to bond backup strips to SMC (sheet molded compound), FRP (traditional fiberglass) and primed metal. Our adhesives provide a full range of hardness, flexibility and worktimes for jobs such as reinforcing the backside of plastic components on vehicles. They use automatic mixing and offer excellent sag resistance.

Effectively Bonds Challenging Materials
When the backside of a plastic component is loosening, or a new component is being installed, 3M™ SMC/Fiberglass Repair Adhesives offer the reliable adhesion that you need for bonding rigid plastics. They securely bond pieces with impervious surfaces. Our adhesives are ideal for small repair areas such as grilles and small gouges, as well as bonding headlamp buckets.

A Highly Versatile Product
In addition to bonding components to SMC, FRP and primed metal, we recommend these adhesives for additional applications including:


Bonding flexible plastics if used in combination with 3M™ Polyolefin Adhesion Promoter, PN 05907.
Under certain conditions, these adhesives may be used as a cosmetic filler. Check with your 3M representative.
Bonding industrial and marine composites.
