Solidification

• Requirements in solidification:

  • Polar to form bonds
  • Fluid to make contact or wet out
  • Able to solidify after
• Water-borne

  • Elmer's glue (PVA + water)
  • When water dries out, glue is really strong
• Solvent-based

  • Evaporates faster
  • Produces toxic fumes
  • Contact Cement (Rugby)
  • Cyanoacrylate Glue (Mighty Bond)
  • Volatile Organic Compounds
• Hot melts

  • Glue stick
  • 100% solid, then is melted, and dries very quickly
• Reactive Adhesives

  • Chemical reaction to solidify
  • Epoxy
• Pressure-sensitive (PSA)

  • Tapes
  • "pressed"
• Plastisols

  • heat reaction
