Enhancing elongation at break - Highlight

  1. 1. Advanced Materials Enhancing elongation at break Quarter 1, 2015
  2. 2. Advanced Materials 2 Table of contents Flexible epoxy building blocks Product selection Elongation at break, modulus and viscosity Tg and water absorption Flexible hardeners Product selection Elongation at break Modulus and glass transition temperature Pot life and time to reach 90% conversion
  3. 3. Advanced Materials 3 Product Reactivity vs. Bis-A epoxy resin at room temperature Impact on mechanical properties vs.Bis-A epoxy resin at room temperature Viscosity (mPa.s) Araldite® DY 3601 Slower 10 times higher elongation 42 - 52 mPa.s Araldite® DY-L Slower 10 times higher elongation 160 - 240 mPa.s Araldite® PY 4122 Slower Very low modulus 25 times higher elongation 700 - 1400 mPa.s Araldite® DY-D Similar Slightly lower modulus 2 times higher elongation 15 - 25 mPa.s Araldite® CY 184 Similar Higher modulus 2-3 times higher elongation 700 - 1000 mPa.s Flexible epoxy building blocks Product selection Flexible hardeners >< Table of content Flexible epoxy building blocks >
