Hot-melt adhesives are supplied as sticks of copolymers of ethene and vinyl acetate. Heat is used to melt the adhesive in the ‘glue gun’ so that drops can be applied to the materials to be joined. Bonding results when the glue solidifies on cooling. Many different types of gun are available with electric or butane cartridge heating and supplying glue at different rates.

These adhesives are supplied as sticks of copolymers of ethene and vinyl acetate. Bonding results when the glue solidifies on cooling. They form fairly strong bonds between many surfaces, eg, cardboard, wood and plastics.

This wide range of epoxy adhesives and polyester resins is produced mostly as two-component systems. Curing is effected by the reactions of a resin and a hardener.

These adhesives are essentially a resin bonding agent (liquid or powder) which sets as a result of chemical action with a hardener. A catalyst may be added to accelerate setting at room temperature.
