Polyurea was originally developed to protect table top edges which led to the development of two-component polyurethane and polyurea spray elastomers took place in the 1990s
The relatively ‘new kid on the market’, polyurea has been used successfully around the world and is known for its excellent physical properties.
Polyurea is applied using a hot spray plural component system and has a fast drying time of under 20 seconds and unlike epoxy can be applied at very low temperatures.
Polyurea needs a primer if used on concrete or brick or porous substrates.
Polyurea provides a seamless, waterproof flexible coating with high tensile strength and excellent abrasion resistance.
Polyurea is a coating technology/product and has been used very successfully for many different applications all around the world.
Polyurea is not a specific coating system by name or specification but it is a polymer technology with a wide range of product formulations that are matched to a particular requirement.
There are not many coating systems that can compare to Polyurea when it comes to attainable physical properties e.g. high elongation, superior tensile strengths, excellent abrasion resistance, high impact resistance, excellent chemical resistance.
Polyurea’s major benefit has to be it’s fast set and return to service characteristics, Tack free within 5-20 seconds and open to traffic within the hour, returning an area to service many times faster than traditional coatings.
Polyurea needs a primer for porous surfaces e.g. concrete, cement, brick etc.
Polyurea has excellent elongation and is ideal for waterproofing the outside of basements and tanks etc. where resistance to high positive pressure and the ability to accommodate building movement is important to the effectiveness of the waterproofing.
For tanking jobs a Polyurea system is highly puncture and abrasion resistant and ideal where backfill and consolidation is part of the project.
Polyurea is sprayed using plural component spray equipment at +70°C.
