Industrial sealants are liquid and viscous compounds used to contain fluids, prevent leaks, and prevent infiltration of unwanted material. They may also include compounds for filling gaps or seams. Industrial sealants are available in a variety of compositions and forms, including liquids, aerosols, powders, and pastes. Many types of industrial sealants are available.

Liquid, aerosol, and powder sealants are three types of industrial sealants. Liquid industrial sealants are flowing liquids with low to moderate viscosities. Aerosol sealants are industrial sealants that are applied by spraying or atomizing a liquid and projecting the droplets onto a surface. Adhesives from aerosol-based industrial sealants are dispensed from an aerosol can or spray gun. Powder industrial sealants are finely-divided particulates, such as Novolac phenolic resins.

Pastes are a common type of industrial sealants. Typically, these industrial sealants require a trowel or gun for applying and pressing into place. Generally, paste industrial sealants that are generally more “workable” and forgiving than fast-setting liquids and aerosols. Pastes include mastics, caulk or grout, filling compounds, gels, and putties. 

Mastics and caulk or grouts are basic types of industrial sealant pastes. Mastics are highly-viscous industrial sealants that are applied by trowel to give thick glue lines with gap-sealing properties. Typically, mastics are used to bond tiles to sub-flooring and to fill gaps or irregularities in a surface before tile or other materials are applied. Caulks, grouts, and joint compounds have a lower viscosity than industrial sealants such as mastics. The low viscosity of these industrial sealants allows the material to pump into joints or cracks for to sealing or repairing.  Most caulks are industrial sealants which consist of a flexible material. Grouts are based on thin-set inorganic mortars, polymers, or resin binders. 

Filling compounds, gels, and putties are popular industrial sealants. Repair and filling compounds are resin-based industrial sealants used to fill-in large gaps, holes, or cracks in a surface. Repair compounds should have a high degree of structural integrity and good adhesion to substrates. Gels are industrial sealants in the form of a high-to-moderate viscosity liquid gel. This type of industrial sealant provides greater run resistance during application. Putty or plastic industrial sealants contain of a very thick consistency that can be molded or formed into place.
