Technical characteristics of Araldite® AW 9102

 

Araldite® AW 9102, combined with Araldite® HW 9102 hardener, offers impressive technical properties:

 

  • Room-temperature curing: It can be used without complex heating equipment, making it easy to apply in a wide range of environments.
  • Mixing ratio: A ratio of 100:40 by weight or 100:47 by volume ensures easy preparation for professionals.
  • Viscosity and pot life: With a viscosity of 8,000 to 20,000 cP at 25°C and a pot life of 80 minutes (for a 100g mass at 25°C), Araldite® AW 9102 offers an excellent compromise between workability and efficiency, enabling complex applications without precipitation.
  • Appearance: Once mixed, the adhesive takes on a pale yellow hue.

 

These technical characteristics, combined with a density of 1.33 g/cm³, make it a stable product, capable of guaranteeing consistent performance even under varied working conditions.

 

Mechanical properties and strength

 

Among the epoxy adhesives available on the market, Araldite® AW 9102 stands out for its outstanding mechanical properties:

 

  • Shear strength: 2,900 psi (20 MPa) on aluminum and 3,625 psi (25 MPa) on steel, guaranteeing high joint strength.
  • Peel strength: 45 N*mm/mm, ensuring excellent resistance to mechanical stress.
  • Glass transition temperature: approx. 52°C, enabling the adhesive to maintain its mechanical properties at moderately high temperatures.
  • Tensile strength: 507 psi (3.5 MPa), an essential criterion in high-stress environments.

Avantages de l’Araldite® AW 9102

 

Araldite® AW 9102 offers numerous benefits, making it an essential choice for professionals seeking reliable solutions:
