Adhesives

Applications:

• Use to join sheets of acrylic together

Advanatges:

• Rapid bonding of acrylics

Disadvantages:

• Can be difficult to apply and give neat joins
• Relatively expensive
• Solvent based so contains VOC's

Applications:

• Used to join high impact polystyrene but not expanded polystyrene

Advanatges:

• Strong bons- melts surface of the epices to be joined and causes them to weld together
• Able to use a brush to apply and absorbed into joints by capillary action

Disadvantages:

• Relatively expensive
• Solvent based so contains harmful volatile organic compounds (VOC's)

Applications:

• Used to join most materials including expanded polystyrene

Advanatges:

• High performance adhesive giving high strength bonds
• Chemical reaction hardens immediately 
• Versatile- is either flexible or rigid, transparent or opaque and thermosetting
• Excellent heat and chemical resistance

Disadvantages:

• Reach full strength only after a few days
• Expensive
• Often requires manual mixing of resin and hardener which can be messy

Applications:

• Used to join woods and other porous materials

Advanatges:

• Gives strong joins
• Relatively inexpensive

Disadvantages:

• Surface needs to be securely clamped together for long periods of time in order for the glue to harden
• Generally not waterproof
