Polyurea Coating

Polyurea coatings have some unique advantages that set them apart from other types of protective coatings. Polyurea is an elastomer substance derived from step-growth polymerization, which involves combining a synthetic resin and isocyanate reactive materials. Thus, the reaction of an isocyanate part with a resin blend component part through the step growth process of polymerization produces polyurea.

Various formulations of resins and isocyanates can provide the desired setting time, moisture resistance, pigmentation, flame retarding properties and other unique features.

Polyurea Coatings has some unique features:

  • Very fast setting (curing time typically 2 to 5 minutes) depending upon the formulation
  • Excellent abrasion and scratch resistance
  • Very stable resistance to weather and environmental conditions
  • Very beneficial elongation characteristics
  • Can be applied in variable temperature conditions, even in high humidity
  • Stable heat resistance up to 130°C (266°F) and short-term rating of 220°C (430°F)
  • Coating thickness can be finely controlled
  • Very effective bonding on correctly prepared surfaces of wood, cement, concrete and metals
  • Excellent chemical resistance
  • Feasibility of low viscosity, thus enabling mixing and spraying at desired temperatures
  • Can be formulated for a very high tensile strength up to 4350 psi

Keeping in view these characteristics polyurea has grabbed a major part of the protective coating’s market. The global market size in 2015 for all coatings and paints was USD $141.58 billion. Of that, polyurea coatings were greater than USD $500 million, with the construction sector making up 40% of the market share. The global polyurea coating consumption in 2014 was 114.3 kilotons. The global market size in 2017 for polyurea coatings rose to USD $684 million and is increasing dramatically. The global market share is expected to reach USD $1.48 billion by 2025, at a CAGR of 10.8% between 2020 and 2025.
