These adhesives are two-part methacrylate, structural bonding adhesives designed for the structural bonding of various substrates, including fiberglass, steel, aluminum, and various plastics (not low energy surfaces).

Epoxy adhesives are part of the class of adhesives called "structural adhesives". Epoxies are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. In general, epoxy adhesives have the highest overall strength and offer the best performance and most resistance to high temperatures, solvents and outdoor weathering. 3M™ Scotch-Weld™ Epoxy Adhesive DP190 is a two-part epoxy adhesive that delivers exceptional performance with high shear and peel strength.
