User manual 3M SCOTCH-WELD STRUCTURAL ADHESIVES SELECTION GUIDE

[. . . ] 3M formulations include the following pastes and liquids: · Epoxy adhesives are available in one and two-part formulations and provide the highest strength at elevated temperature and chemical resistance of all 3M adhesives. · Acrylic adhesives bond the widest variety of substrates including hard-to-bond plastics and oily metal. The distinction is high strength bonding without the surface preparation needed for epoxies and urethanes · Urethane adhesives are generally lower cost and cure quickly to an elastic bond in applications requiring flexibility between dissimilar materials. Impact resistance is a distinctive characteristic. [. . . ] For the best adhesive bond, there should be at least a . 003"-. 005" gap between the parts for shear and 0. 015" - 0. 020" for peel . The gap should be as consistent as possible. Q8 To what types of stress will the bond be subjected?Strength can be readily matched to the substrate and stress characteristics to which the bond will be subjected. Most adhesives and tapes perform better when the primary stress is tensile or shear. In most industrial applications, however, a combination of stresses are involved that may include cleavage and peel. Tensile Shear Cleavage Peel 2 Tensile is pull exerted equally over the entire joint. Pull direction is straight and away from the adhesive bond. Shear is pull directed across the adhesive, forcing the substrates to slide over each other. Cleavage is pull concentrated at one edge of the joint, exerting a prying force on the bond. The other edge of the joint is theoretically under zero stress. Peel is concentrated along a thin line at the edge of the bond where one substrate is flexible. The line is the exact point where an adhesive would separate if the flexible surface were peeled away from its mating surface. Once peeling has begun, the stress line stays out in front of the advancing bond separation. Q9 What is the preferred method of application?Depending on formulation, 3M structural adhesives are available in a variety of cartridge sizes, 5-gallon pails, and 55-gallon drums. You can apply manually or with automated bulk systems. For more details. . .
