MECHANICAL PROPERTIES OF EPOXY STRUCTURAL ADHESIVES AS A FUNCTION OF CURING TIME

MECHANICAL PROPERTIES OF EPOXY STRUCTURAL ADHESIVES AS A FUNCTION OF CURING TIME

Full article:

The present study aims to evaluate the influence of curing time on the tensile and shear mechanical properties of epoxy structural adhesives. From the results, it was observed that, depending on the adhesive used, the curing time may influence the shear strength properties of bonded metal joints (steel SAE 1020) and tensile strength. For Betamate™ 2096, an increase in mechanical properties was observed when a curing time of 7 days was used at room temperature, while for Scotch-Weld™ DP420NS Black, the results remained unchanged, regardless of the curing time. This influence is associated with the curing conditions, which depend on the catalyst and additives used in the formulation when comparing materials with the same chemical base.
