Adhesives, mastics, putty, sealants, plasters and paints are the various types of adhesives known to contain asbestos. They include:
- Asphaltic cutback adhesive: This is black in colour and is usually found beneath vinyl tiles and flooring. Asbestos was mixed with this product to make it more durable.
- Cement adhesive: This is also called furnace cement or stove cement and is a type of joint compound and adhesive used in areas exposed to extreme heat. Furnace cement may be used in boilers, stoves, chimneys, kilns, refractories and manufacturing plants.
- Duct adhesive: Commonly available in the form of tape (similar to duct tape) and sprayable adhesive, this product was often used in HVAC systems to prevent cool or warm air from escaping and affecting the temperature of a climate-controlled home or building.
- Emulsion adhesive: This is a synthetic form that was used to bond synthetic laminates, like roofing or floor tiles, to wood and timber.
- Fibrous adhesive: This liquid form was typically applied with a brush or sprayer. Through the years, fibrous forms of asbestos-contaminated adhesive often broke down, which generated dust. The dust created by the crumbling fibrous adhesive often allowed toxic asbestos particles to enter the air, where they presented a serious health hazard to individuals nearby.
- Lagging adhesive: This water-based product was used in heating and cooling systems to seal ducts and ventilation corridors against the leakage of temperature-treated air.
- Mastic adhesive: Made from sticky resin of the mastic tree, this type is available in a variety of forms, including liquid and glue. It was commonly used in the construction and heating and air industries.
- Seals: Seals are used to prevent leaking in roofing materials by joining roofing shingles together. Seals, or packing, protect the roofs of homes and other structures against high temperatures and caustic substances. Roof seals prevent leaking and weather damage and have been used to protect against bleaching, cracking, UV exposure and rain damage.
