Influence of adhesive bond line thickness on joint strength
WebRecommended Bond Line Thickness for Adhesive Bonding. For standard epoxy and ceramic adhesives a bond line thickness of 5-8 mils (0.005" - 0.008") will produce excellent results. for Cotronics' non-sag putties (epoxy or ceramic) bonds of 0.020" or more can be used. To form a thick layer, or section, apply putty in several layers curing between ... WebBond Line Thickness vs Thermal Resistance vs Bond Strength A “fillet” at the edge of a bond line is suggested to increase bond strength. The fillets are formed as the epoxy squeezes out past the side edges. Fillets can add strength to the assembly. 3M™ Thermal Conductive Epoxy TC-2810 is supplied in dual syringe plastic duo-pak cartridges ...
