ASTM E229 Standard Test Method for Shear Strength and Shear Modulus of Structural Adhesives

The ASTM E229 test covers the determination of the shear strength and shear modulus of structural adhesives occurring in thin glukelins that are constrained by relatively higher modulus adhesions.

ASTM E229 Standard Test Method for Shear Strength and Shear Modulus of Structural Adhesives

Structural adhesives are one or two component adhesives. In general, they are effective in bonding metal, ceramic, marble, glass, wood, thermoplastic, composite and some plastic materials. Its resistance against uninterrupted jams, impacts and hammer power has been strengthened. Solidification occurs by a chemical reaction between one component or two components.

Fixation time can range from a few seconds to several minutes or hours, depending on the system chosen. Heat accelerates hardening. It is extremely resistant to water, oils and fuel-type substances.

Structural adhesives designed for use in engineering activities in many industries offer reliable, long-lasting bonding and sealing where needed due to load bearing and other structural conditions. A wide range of products available for use on many different surfaces, materials and applications; These cured acrylics, polyurethanes, cyanoacrylates, anaerobics, phenolics, vinyl acetates and epoxy structural adhesives provide a wide range of applications for industrial and commercial use.

Shear strength values ​​of some adhesives:

  • Thermosetting, densely cross-linked adhesives (epoxy/phenol resins) - 25-35(N/mm2)
  • Room temperature curing epoxy resins - 20-30(N/mm2)
  • Polymerization adhesives (methacrylate, cyanoacrylate) cured at room temperature - 10-20(N/mm2)
  • Reactive polyurethane hot melt adhesives - 5-10(N/mm2)
  • Thermoplastic hot melt adhesives - 10-15(N/mm2)

Values ​​stated in inch-pound units should be considered standard. Metric equivalents of inch-pound units can be approximate.
