Polyurea Benefits

Polyurea Offers Many Advantages

Almost no coating can compare to polyurea when it comes to attainable physical properties.

Polyurea is a truly remarkable coating, lining and joint sealant technology and can be used for a wide variaty of applications. Polyurea coatings and linings are commonly applied over concrete and steel for corrosion protection and abrasion resistance. They also have numerous advantages over conventional materials due to their extremely fast setting times, high elongation, extreme resistance to atmospheric attack and their durability abrasion characteristics.

Polyurea Benefits

No VOC´s and, depending on the formulation, odour-free

Application temperature: -30°C to +60°C, even in high humidity conditions

Fast reaction, which means the sprayed surface can be returned to service quickly

Excellent heat resistance up to 130°C, short-term up to 220°C

Considerably better UV stability compared to polyurethanes

Waterproof (acts as a seal) and hydrolysis stable

High tensile strength, in the order of 1450 - 4350 psi (10 – 30 MPa)

Large elongation at break, in the order of a few hundred to 1000%

Flexible (bridges cracks)

Can be applied at any thickness

Excellent bonding to properly prepared substrates

Good chemical resistance

Simple machine processing due to low viscosities

Realities of Polyurea

Polyurea protective coatings like all industrial protective coatings have performance limitations and minimum surface preparation requirements.

Polyurea is:

  • A fast-setting coating system
  • Applied smoothly without seams
  • Applied at any thickness
  • Chemical and abrasion resistant
  • Long lasting
  • Ecologically friendly

Polyurea is not:

  • A coating-system for everything
  • A simple technology
  • A stand-alone application
  • The lowest cost solution

Four Key Factors

Polyurea coatings always have to be looked at as a complete system. A successful coating is the coordinated combination of 4 factors. These parameters must be met correctly at all times to make use of the unique benefits of the Polyurea systems.

  1. Proper preparation of surface area
  2. Polyurea formulation and primer selection
  3. Professional equipment
  4. Trained application teams
