Contact Adhesive

Advantages:

  • Bonds unlike materials
  • Bonds form quickly (less need for clamping together)
  • Ideal for gluing large sheets of materials
  • sold in metal tubes - easy to apply

Disadvantages:

  • Applied to both surfaces, need to allow time before being stuck together
  • Relatively expensive
  • Solvent-based - contains volatile organic compounds (VOC)

Acrylic Cement

Advantages:

  • Rapid Bonding of acrylics

Disadvantages:

  • Can be difficult to apply
  • Can be difficult to give a neat joint
  • Relatively expensive
  • Solvent-based - contains volatile organic compounds (VOC) 
2 of 5

Polystyrene Cement

Advantages:

  • Strong bond (melts surface so pieces weld together)
  • Water like consistancy (able to use a brush to apply)

Disadvantages:

  • Relatively Expensive
  • Solvent-based - contains volatile organic compounds (VOC)
3 of 5

Epoxy Resin

Advantages:

  • High strength bonds
  • Chemical reaction hardens immediately
  • Versatile (can be flexible, rigid, transparent, opaque, coloured, rapid or slow setting)
  • Excellent heat and chemical resistance

Disadvantages:

  • Reaches full strength after a few days
  • Expensive
  • Can be messy (requires manual mixing of resin and hardener)

Polyvinyl Acetate (PVC)

Advantages:

  • Strong Joint
  • Relatively inexpensive

Disadvantages:

  • Surfaces need to be securely clamped for a long time
  • Generally not waterproof
