Adhesives
Adhesives are bonding agents used to join materials by glueing. Adhesives can be used in construction in many situations:
- Carpet laying.
- Ceramic tiles.
- Countertop lamination.
- Drywall lamination.
- Flooring underlay.
- Glulam.
- Heating, ventilation, air conditioning connections.
- Timber jointing.
- Manufactured housing.
- Pre-fabricated panels.
- Resilient flooring.
- Roofing.
- Wall coverings.
The most common types of adhesive are as follows:
- PVA (polyvinyl acetate): A general purpose woodwork glue, with some water resistant properties.
- Synthetic resin: A strong water-resistant woodwork glue.
- Epoxy resin: Used for metals and plastics.
- Acrylic cement: Used for acrylic and some types of plastic. The adhesive ‘melts’ the surface of the plastic and fuses it together.
- Casein: Made from sour milk. A cold setting adhesive in the form of a powder which is mixed with water.
- Urea formaldehyde: A cold setting resin glue. Although moisture resistant, it is usually restricted to timber members used in dry, unexposed conditions as it loses strength after prolonged exposure to water or heat.
- Resorcinol formaldehyde: A cold setting glue that is suitable for timber members used in external situations. Will set at temperatures down to 15°C and does not lose strength at high temperatures.
- Phenol formaldehyde: A warm setting adhesive that requires a temperature of above around 86°C to set.
