3M™ Scotch-Weld™ Epoxy Adhesive DP190 is a two-part, room-temperature curing epoxy available in translucent and grey versions. It has a 1:1 mix ratio by volume, a long worklife (80–90 minutes), and cures to a flexible bond with high peel and shear strength.
DP190 Translucent: Flexible, clear-to-amber, with higher elongation.
DP190 Grey: Stronger, stiffer cure, excellent shear strength, good environmental aging resistance.
Bonding of metals, plastics, glass, wood, and composites.
Suitable for structural bonding where flexibility and peel strength are required.
Used in electronics, general industrial assembly, maintenance, and repair.
Compatible with 3M™ EPX™ Applicator System for precision mixing and dispensing.
