Spreading acrylic cement on joint surfaces; pouring from a large stock container to smaller containers.

 

These adhesives are used in very small amounts and set by virtue of a moisture-catalysed polymerisation process. They form very strong instant bonds between non-absorbent surfaces, eg, metal, glass, plastics, rubber and hardwoods.

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.
