Different types of sealants for varied purposes

What is a sealant?  A sealant is typically a sticky material that changes its state to become solid and is widely used to avoid the penetration of air, gas, noise, dust, fire, smoke or liquid from one location through a barrier into another. Generally sealants are used to close small openings that are otherwise difficult to close using other ways such as concrete, drywall, etc. The properties of sealants include insolubility, corrosion resistance, and adhesion. The sealants are used widely in different industries including construction, automotive and aerospace.

The basic difference between adhesives and sealants is that sealants generally have lower strength and higher elongation than adhesives. As the primary objective of a sealant is to seal joints and assemblies, sealants must need to contain sufficient adhesion to the substrates and resistance to environmental conditions to keep stick over the stipulated time period.

The different types of sealants include Acrylic sealants, Asphalt sealants, Pipe thread sealants, Acoustic sealants, Adhesive sealants, Aerospace sealants, Aircraft sealants, Concrete sealants, Construction sealants, Dental sealants, Elastic sealants, Electronic sealants, Engine sealant, Extruded sealants, Floor sealant, Foam sealants, Gasket sealants, Glass sealants, Hydraulic sealants, Impregnating sealants, Marine sealants, Metal sealants, Military sealants, Radiator sealant, Reservoir sealants, Rubber sealant, Surgical sealant, Tyre sealants, Valve sealants, Wood sealants, etc.
