Taking a Dive into Polyurea Coatings

Polyurea coatings have advantages setting them apart from other coatings. They also have some special requirements. This blog has a few points that you should know before considering these coatings.

What is Polyurea?

Polyurea is an elastomer material resultant from step-growth polymerization. It includes combination of an isocyanate and artificial resin reactive materials. Therefore, the reaction of resin mixture with isocyanate through the step-growth procedure of polymerization helps in producing polyurea.

Numerous preparations of isocyanates and resins can offer flame retarding properties, desired setting time, moisture resistance and other features.

A hybrid coating is a polyurea mixed in polyurethane with fixed proportions. The hybrid coating offers specific properties of the unadulterated polyurea at low costs.

How Aromatic Polyurea and Aliphatic Polyurea Are Different?

Polyureas resultant from aromatic diisocyanates are distinguished by UV light sensitivity.

Non-natural UV light or sunlight contact can deteriorate the polyurea’s color change and properties like chalking and darkening. Aromatic polyurea is a low-cost substitute but not appropriate as top coat; it is good for base coat application.

Polyureas are resultant from aliphatic diisocyanates fight color change because of contact to sunlight. They require to maintain their properties under UV exposure conditions also. They are favored for outdoor use as they can help recover aesthetics with a silky appearance and can be utilized to lower film width by about 30 mills. Though, it could be exclusive compared to aromatic polyureas because of the complex process.

Features of Polyurea

No coating system is able to swap polyurea.  It is because of durability and exclusive physical properties. Though, the surface preparation necessities of polyurea are stringent.

It protects concrete, steel, and wooden surfaces and structures from corrosion and abrasion. It can preserve a worsening concrete structure, repair and keep canals intact. It fights commercial and industrial floor applications’ oils, salts chemicals, and grazes. It can preserve boats and vessels by protecting them from cracking.

Application for Polyurea Coatings

•  Material Handling and Automotive Industry

The automotive industry is using polyurea coating for long. The coating is prevalent due to its impact resistance and other properties.

Polyurea provides abrasion protection in construction and mining apparatus and lining dumpers beneficial for abrasive materials such as coal and metallic and coal ores. It guards rollers and conveyors systems transporting stones, metallic ores and abrasive coal.

•    Irrigation

Polyurea protects against corrosion and abrasion of pipelines carrying out abrasive and corrosive materials. It is applied as the base for preventing cathodic disbanding.

•    Security and Defense

Polyurea coating has durability and quick setting. It can captivate explosive energy, and impact resistance can easily be used in the security and defense.

Surfacing of Concrete and Steel Bridges

Polyurea is used for initial coating and as a repair coating because of its fast-curing, impact resistance, extension, and strength. Polyurea’s structure makes it a higher durability elastomer. It is the secret of its aptness in construction and other kinds of fields.

Due to its diverse applications, the demand for polyurea coatings is on the rise and will reach a value about $2,554 million by 2030.
