Polyurea lining technology boasts excellent chemical resistance to many liquids, owing to its high build-thickness characteristics, rapidly drying finishes and very low perm ratings. Polyurea is ideal for a variety of waterproofing, corrosion control, immersion and lining applications.
Polyurea can be applied over a variety of different substrates, such as concrete, metal and wood, and is similarly flexible in applications of varying temperature and humidity. However, like all protective coatings, polyurea is no excuse for failing to perform proper surface preparation and quality control testing during the application process.
Polyurea offers excellent adhesion to properly prepared surfaces and is used as an alternative to epoxy, polyurethane, fiberglass and other mat reinforced lining systems. Polyurea coatings combine high tensile strength and elongation properties with low permeability and high impact resistance, making them ideal where a tough, flexible (or hard) liner is needed.
Polyurea is commonly used as a material for lining primary containment tanks as well as a lining system for secondary containment structures. Many of the world's sea aquariums have turned to polyurea lining technology due to its quick return-to-service characteristics, ability to achieve UV stable colors, and its superior physical properties over conventional linings.
Polyurea is also used extensively in the water and wastewater industries and is the ideal liner for most water tanks, even for those containing salt water. Polyurea can even withstand most chemical gasses produced at waste treatment plants. Several polyurea systems are available for potable water applications and are USDA-acceptable and NSF-approved to ANSI-NSF 61 standard for potable water storage.
Polyurea is also recommended for lining large diameter pipes, manholes, clear wells and process tanks for basins, reservoirs, potable and non-potable water, lift stations and reserve water tanks for fire-fighting.
Polyurea contains no VOCs, and are also available in brush grade for touchups and repairs, as well as caulk grade for horizontal joints.
