Polyurea, a popular industrial coating is an extremely hard, smooth and durable plastic. It is frequently used as a building and industrial sprayed coating. It is also commonly used as a protective coating on glass products. Here are some polyurea facts and some polyurea benefits.
Polyurea is composed of thousands of tiny bubbles that are electrically charged. The bubbles bond together with other polyureas and create a solid and non dispersible coating. It is a very strong seal that has the ability to prevent concrete from deteriorating. Polyurea is an ideal type of polymer for protecting concrete against erosion, crushing, and direct sunlight, and most types of abrasive cleaners are unable to penetrate it. The polyurea is largely responsible for the non-sparking effect of friction, thus preventing damage to roof shingles, roof panels and concrete surface.
The polyurea coatings have applications in several industries. It is commonly used as floor and wall tiles in concrete slabs, counter tops and flooring in industrial buildings. Polyurea coatings are commonly used in the automotive, refrigeration and food service industries. The polyurea coatings are also used in the printing and coating sectors for application in photo foil, laminates, and mats.
Polyurea is extensively used as a protective coating because of its non-sparking and elasticity enhancing physical properties. Its high flexibility and low-sparking characteristics make it an ideal barrier, but is able to resist extreme temperature fluctuations. It is able to maintain its original colour and clarity even in a wide range of conditions. This is because the coating is made up of a thick polymer layer that is resistant to chemical reaction and physical erosion and is long lasting.
Polyurea coating is comparatively more expensive than other common materials such as steel, fiberglass and aluminum because of the physical properties of polyurea. However, polyurea‘s extreme durability and excellent tensile strength makes it cost effective in the long run. Its resistance to heat and cold makes it an excellent choice for applications where high impact resistance is a requirement. It has excellent physical and chemical resistance and therefore can resist corrosion, impact and abrasion.
Polyurea coatings have excellent moisture absorption capacities. However, they tend to dry out faster during contact with moisture. Thus they are better suited for drywall applications and other applications where fast drying is required. In cases of humidity, polyurea tends to expand and contract. It can also be damaged by ultraviolet light, ozone and barium oxidation.
