Advanced Polyurea Waterproofing & Coating Systems

Polyurea coating technology constitutes a more recent and advanced system than the traditional ones used in waterproofing and protective coating applications.
However, it is not a new technology. In fact, it has been around and in use for almost three decades now.
The technology is based on the reaction of an isocyanate component with an amine blend. The isocyanate can be of aromatic or aliphatic composition. This reaction is rapid, proceeding to completion within a few seconds, thus requiring specialized mixing and application equipment to be used by a specialized application crew.

Major advantages-properties of all Polyurea based products

  • Ultra fast curing. Return to service or to further procession comes many times faster than traditional coatings. Gel time is achieved within seconds, allowing foot traffic after a few minutes, so the facility could be back in use in less than one day.
  • Impressive chemical resistance and exceptional mechanical properties like elongation, tensile strength, tear strength, abrasion resistance and crack-bridging ability. Almost no coating can compare to Polyurea when it comes to attainable physical properties.
  • Insensitivity to humidity during application. Polyurea is hydrolytically stable so relative humidity or residual moisture have little to no effect on adhesion or coating performance.
  • Thermal stability to temperature variations. Weather variations hardly influence coating performance or adhesion properties.
  • Solvent free, consisting of a 100% solids formula. Polyurea products are considered environmentally friendly.
  • Rapidly applied with a special two-component, high-pressure and temperature spray machine.
  • Monolithic, seamless membrane after curing. Polyurea membranes have high resistance even to heavy mechanical or chemical loads. Furthermore these membranes are vapour permeable, preventing moisture accumulation.
  • Applicable also on vertical and curved surfaces. Complicated architectural structures and details can be coated in almost any desired thickness, without sagging.
  • Relatively unlimited application thickness in one pass.
  • Good adhesion to a variety of different substrates (concrete, metals, wood etc.) even under high humidity and extreme temperatures.
All Polyurea membranes should not be left exposed to UV radiation. In these cases, a UV-stable protective coating is recommended as a final layer, such as TOPCOAT-PU 720 or TOPCOAT-PU 740 of ISOMAT.

The Polyurea product range of ISOMAT


Two-component, hot spray applied, pure polyurea membrane, highly resistant
100% pure polyurea, derived from a reaction between an aromatic, isocyanate prepolymer and an amino resin. Ideal for use as a protective coating on floors subjected to heavy vehicle traffic and high chemical stress.

  • As an elastomeric protective coating on industrial floors, in car parks, light to heavy vehicle traffic areas, auto repair shops, truck trailers, water tanks and plumbing installations, wastewater and biological wastewater treatment tanks, settling tanks, swimming pools, aquariums, recreation areas, craft businesses, warehouses etc.
  • As a non exposed waterproofing membrane in bridges, tunnels, industrial areas, flat roofs, balconies and terraces.
