Urea Spray 400 – Waterproofing and Protection with Polyurea

Polyurea is a 2 component polymer (isocyanate and a mixture of resins) that forms a continuous, waterproof coating that has no harmful effect on the environment. It is used for surface waterproofing and protection against mechanical and chemical stress, abrasion and corrosion.

Polyurea is an extremely durable product due to its excellent mechanical and chemical resistance. It is biologically stable and has a high resistance when exposed to corrosive substances, acids, alkali or hydrocarbons (oil, grease, etc.).

MAIN CHARACTERISTICS

  • Fast curing (can be walked on in 5 minutes), easy to maintain and long term durability
  • Excellent waterproofing and anti-corrosive protection properties
  • High thermal stability
  • High mechanical and chemical resistance:
  • Elongation 400%, fits perfectly on the surfaces
  • It forms a continuous, waterproofing & protective coating without joints
  • Solid content 100%, free of VOC
  • High abrasion, impact, wear resistant
  • UV resistant

USES

Due to its remarkable mechanical, chemical and thermal characteristics the elastomeric polyurea coating can be successfully used in a large range of applications:

  • Flooring systems
  • Roofs, green roofs
  • Foundations
  • Tanks, clarifiers, digesters
  • Underground steel pipes
  • Food & drinks processing areas
  • Factories
  • Production facilities

WHY POLYUREA?

Polyurea vs. polyurethane resins:

  • Larger working temperature range
  • Free of catalyst – low risk of blistering
  • Superior braking resistance,
  • It can be applied below 50C

Polyurea vs. epoxy resins:

  • It has the same performance in exterior areas
  • Higher abrasion and impact resistance
  • It can be applied below 50C

TYPES OF POLYUREA

UREA SPRAY 400 – aromatic polyurea with the elongation at break of 400% and highly resistant to abrasion and corrosion.

UREA SPUR – aromatic polyurea for soft substrates: roofing, polyurethane foam, etc.
