3M Scotch-Weld DP-125 Grey Epoxy Adhesive - 400ml Dual Cartridge

Our 3M™ Scotch-Weld™ Epoxy Adhesive 125 is a versatile, medium viscosity, epoxy adhesive that pours easily with minimal dripping, running and migration that will flow smoothly for a controlled, accurate dispensing. Its flexibility makes it ideal for applications involving dissimilar surfaces, where coefficients of thermal expansion are a consideration, for example when bonding glass to metals. Flexible, High Strength Compared to common 5 minute epoxies, this flexible, longer work life product provides better plastic and glass bonding, lower Odour and flexibility for higher peel and impact resistance. The mix ratio is 1:1 and provides a 25 minute work life to allow plenty of time for positioning and to adjust for fit prior to setting. The adhesive reaches handling strength in approximately 2.5 hours and is fully cured in 7 days (at 72°F/22°C). This adhesive is available in a variety of package sizes to suit the needs of the user and the job. What Are Epoxy Adhesives? Epoxy adhesives are part of the class of adhesives called structural adhesives, which also includes polyurethane, acrylic, cyanoacrylate, and others. Epoxies begin as liquid reactive polymers that undergo a chemical chain 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 need. This working time lasts anywhere from a few minutes to 48 hours or longer. Depending on the specific formulation, this class of structural adhesives can provide very high shear and peel strengths, and better heat and chemical resistance than other common adhesive.
