DP8425NS Scotch-Weld Green Acrylic Adhesive

3M DP8425NS Scotch is a green coloured, high performance, two-part acrylic adhesives that offer excellent shear, peel, and impact performance. 3M Scotch-Weld Acrylic Adhesive DP8425NS is a non-sag acrylic adhesive with a 10:1 mix ratio. It features a 23 minute work life to allow time to position substrates prior to adhesion. This working life, open time and cure time can be accelerated with heat. Once fully cured, this adhesive will reach 1,000 psi (7 MPa) of overlap shear strength in approximately 53 minutes, increasing throughput and productivity while featuring a high peel and impact performance. Full cure will be reached within 24 hours. Typically used for larger parts where a longer open time is needed for assembly.

Acrylic adheisves are two-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 much 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.
