Fast 5 Minute Work Life with Handling Strength in 20 Minutes
The mix ratio for 3M™ Scotch-Weld ™ Epoxy Adhesive DP100 is 1:1 for quick, precise dispensing, and with a 5-minute
working time there's some opportunity for repositioning for precise alignment of parts. The adhesive reaches handling
strength in approximately 20 minutes and is fully cured in 48 hours (at 72°F/22°C). UL 94 HB certified.
Understanding Epoxy Adhesives
Epoxy adhesives, including 5 minute epoxy are part of the class of adhesives called "structural adhesives," which
include polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid reactive polymers that
undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two parts are mixed
in their specified ratio, they begin the curing process and offer a limited working time where the adhesive can be
applied and the two surfaces positioned as needed. This work life lasts anywhere from a few minutes to several hours.
These structural adhesives provide high shear and peel strengths, depending on the formula, and better heat and
chemical resistance than other common adhesives. In general, epoxy adhesives have the highest overall strength and
offer the best performance and most resistance to high temperatures, solvents and outdoor weathering.
Epoxy adhesive (often referred to as epoxy glue) is widely used in building and home construction; aircraft and
automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and
other applications. It is used virtually anywhere high-strength bonds are needed along with resistance to environmental
conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance.
Formulations can be created to make epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or
opaque, quick setting or slow setting. The versatility with which these adhesives can be formulated helps meet almost
any requirement for bonding wood, metal, glass, stone and various plastics.
