Efficient sealing for power units and control units. It contains 0.03 in (0.75 mm) spacer beads to help prevent excessive squeeze-out of adhesive due to over-clamping. The highest point of the stress–strain curve is the ultimate tensile strength and has units of stress. Smooth & Remove Tools. The choice of AA was primarily related to the presence of the carboxylic acid group in the triblock copolymers, which provided high T g and expanded the applicability of the copolymers as adhesives owing to its high hydrophilicity. It is suitable on substrates such as steel, aluminum, stainless steel, epoxy-coated metal, SMC and plastics. These include: Average Stress Method: This approach assumes that the strength of the joint is equal to the average shear or normal stress in the adhesive layer at the point of failure (i.e. Different adhesives are used for joining the different types of materials. Adjustable Flow Spray Gun for Glue Canisters.
