Description

3M™ Scotch-Weld™ acrylic adhesive DP820 is a 2-part acrylic adhesive specially formulated to bond many plastics, metals and oily metals. When using a duo-pak (DP) size adhesive, rely on 3M™ dispensing equipment for convenient and accurate metering, mixing and dispensing. Structural bonds can be achieved without special surface treatments such as chemical etching, plasma, flame or corona treatment or priming. Simply wipe the surfaces with isopropanol to remove mold release agents, dust dirt, etc. 3M™ Scotch-Weld™ adhesive DP820 also bonds metals and most other plastics. The mix ratio for our 3M™ Scotch-Weld™ acrylic adhesive DP820 is 1:1 for quick, precise dispensing. With an applied 15 min work life there is some opportunity for positioning and adjustments after the adhesive is applied. This adhesive reaches handling strength in approximately 40 min and is fully cured in 48 hr (at 72 deg F/22 deg C). Acrylic adhesives are 2-part methyl methacrylate adhesives (MMA) that provide excellent bond strength and durability. Often referred to as epoxy adhesives or epoxy glue, acrylics actually belong to a separate chemical family with their own unique characteristics. Acrylic glues have several features that make them easier to use, including a faster cure speed, higher tolerance for oily or unprepared bonding surfaces and the ability to bond a wide variety of materials, including nearly all plastics. Newer acrylic adhesive formulations are room temperature stable with a long shelf life.
