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.
