Polyurethane is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue. Since its invention during the 1940s by Prof Otto Bayer, polyurethane has been used in a wide range of items, from baby toys to airplane wings, and it continues to be adapted for contemporary technology.
Applications of Polyurethane
Polyurethane systems have proven to be extremely reliable in floor coating and insulation applications.
Many modern coatings, whether for vehicles and cables, floors and walls, or bridges and roads contain polyurethanes, which safely and effectively shield exposed surfaces from the elements and various forms of pollution, so that they look better and last longer.The durability, corrosion resistance and weather resistance of polyurethanes makes them suitable for coating all kinds of surfaces. Applications range from concrete constructions like bridges and motorway structures, to steel railway carriages and wooden furniture.
The most important application of polyurethanes in buildings is insulation. Polyurethanes are regarded as an affordable, durable and safe way of reducing carbon emissions that lead to global warming. Polyurethanes can dramatically reduce heat loss in homes and offices in cold weather. During the summer, they play an important role in keeping buildings cool, which means air conditioning is needed less.
Polyurea is a fast curing two-component coating and insulating system,can be applied by spraying method. Polyurea has 6000 psi (40MPa) tensile strength and is 500% elastic and closest to carbon hardness.The main issue everyone must understand is that, Polyurea by name is not a specific coating system or a specification, it is a description of a polymer technology. A great technology that boasts so many different formulations and physical property ranges. They also have tremendous advantages over conventional materials for joint fill and caulk applications due to their fast set nature, high elongation and durability/abrasion characteristics
Applications of Polyurea
Polyurea is truly a remarkable coatings,insulation and joint sealant technology. It is being used successfully for so many different applications today. Polyurea coatings and linings are more commonly applied over concrete and steel for corrosion protection and abrasion resistance.Polyurea can be molded and shaped by spraying it into molds.
It has numerous application fields such as Pipeline Coatings&Linings,Bridge Coating, Tank Coatings&Linings,Marine,Roof Coating,Waste Water Treatment Linings,Manhole & Sewer Linings, Flooring and Parking Decks,Landscape & Water Containment,Water Parks & Playgrounds, Railcar Lining & Track Containment.
The markets and applications are endless and rapidly on the rise.Polyurea's future uses are limited only to one’s imagination.
Properties of Polyurea
An epoxy coating or paint is a protective material made from epoxy-based resin. It provides outstanding resistance to corrosive chemicals, heat, and ultra-violet light; has convenient drying times; exhibits excellent dimensional stability, extreme toughness, and abrasion resistance; and provides strong adhesion to a wide range of substrates, including glass, metals, fibers and numerous other modern materials. An epoxy coating may be used in a wide range of interior and exterior applications across many industries including building and construction, electronics, and agriculture
Applications of Epoxy
Epoxy has wide range of applications for coating systems. It is used as decorative coatings and binders for building materials in construction applications which includes restoration and protection of concrete. Epoxy applications are very effective in areas that require high esthetics and decorative properties although high foot and vehicle traffic. Epoxy provides good adhesion and long-term mechanical properties on various surfaces. Epoxy applications can be used in mumerous areas such as ships,bridges,pipelines and chemical plants.
