ISOMAT-PUA 1360

ISOMAT-PUA 1360 is a two-component, highly elastic, ultra fast-curing, 100% solids, hot spray-applied, pure polyurea membrane, obtained from the reaction of an aromatic, isocyanate prepolymer withan amino resin. Thanks to its special composition, the reaction takes place within seconds and the final product deliveres excellent mechanical and chemical resistance to any substrate type. It is applied with a special two-component, high pressure and high temperature spray equipment offering the following advantages:

  • Very high elasticity that allows application even in extreme climatic conditions or complex architectural structures.
  • Very quick reaction; gel time in seconds.
  • Areas can be returned to service immediately. Pedestrian use may begin within minutes after application.
  • Low to no sensitivity to atmospheric conditions, such as relative humidity and temperature.
  • ~100% solids and odorless or nearly odorless.
  • Excellent physical-mechanical properties: ultimate tensile stress, crack-bridging ability, abrasion resistance, etc.
  • Very high chemical resistance. Recommended for use in casesof heavy chemical loads.
  • Thermal stability at very high temperatures.
  • Wide range of layer thickness in one application.
  • After curing, a vapor-permeable membrane is formed, preventing moisture accumulation.
  • Forms a jointless and seamless, monolithic surface.
  • Can also be safely applied to vertical surfaces.

ISOMAT-PUA 1360 complies with all the requirements established in Royal Decree 140/2003, modified by RD 314/2016 and RD 902/2018, which establishes sanitary criteria for the quality of water for human consumption. Water tanks must be thoroughly washed prior to filling with potable water.
Polyurea is used in a large number of waterproofing and protection applications and is selected when the primary objective is high mechanical strength, chemical resistance, fast completion of work and immediate retur-to-service. ISOMAT-PUA 1360 is ideal for substrates subject to some kind of vibration. Other areas of use:

  • Waterproofing of industrial refrigerators and generally areas subject to extremely low temperatures or extreme temperature variations.
  • As a water insulation layer in roofs, balconies and terraces.
  • Waterproofing of metal roofs or metal bridges.
  • On industrial floors in parking garages and traffic areas, auto repair shops, etc., as a protective coating against abrasion and impact.
  • As an elastomeric protective coating for truck trailers.
  • As shock-absorbing flooring for the prevention of injuries in playgrounds.

Could also be used as a waterproofing protective layer:

  • In potable water tanks.
  • In wastewater and biological wastewater treatment tanks etc.
  • In swimming pools, aquariums, recreation areas.
  • On floors in industrial facilities, craft businesses, warehouses and surfaces subject to high mechanical and/or chemical loads.

Substrate preparation
Polyurea may be applied on most substrates using a suitable primer, following appropriate preparation. The substrate must be resistant, dry (moisture content < 4%) and free from loose material, dust, oil and other contaminants.

Concrete surfaces
Cavities in the concrete must be filled with proper repair materials. Deep cracks on the substrate must be sealed with one of the polyurethane sealants FLEX PU-30 S FLEX PU-50 S. After the surface is properly prepared, it is primed with the one-component polyurethane primer PRIMER-PU 100 (or the two-component polyurethane PRIMER-PU 140). The primer should be applied uniformly over the entire surface using a brush, roller, or spray gun with a consumption of approx. 200 g/m2. ISOMAT-PUA 1360 may be applied 2-3 hours after the application of the polyurethane primer and while the surface is still tacky. In any case, the waiting time after the application of the primer should not exceed 24 hours. Alternatively, DUROPLOOR-PSF two-component, solvent-free epoxy primer is applied using a brush or roller in one layer, with a consumption of 200-300  g/m2. After the application of DUROFLOOR-PSF and while this is still fresh, quartz sand must be broadcast. The quartz sand must be completely dry. Once the primer has cured, remove any residual quartz sand grains using a high-suction vacuum cleaner. The membrane must be applied within 24 hours from the primer application.

Smooth – Non-absorbent surfaces
Smooth and non-absorbent surfaces with a moisture content > 4% as well as surfaces of bituminous membranes or old waterproofing layers, after being cleaned of residue, loose material and anything that might affect adhesion, are primed with the two-component, water-based epoxy primer EPOXYPRIMER 500. The primer is uniformly applied over the entire surface using a roller, brush or spray gun, thinned with water up to 30% by weight, with a consumption of 150-200 g/m2. ISOMAT-PUA 1360 may be applied within 24-48 h from priming and as long as the moisture content of the primer falls below 4%.

Wooden surfaces
The substrate must be resistant, dry (moisture content < 4%), and free from loose material, dust, oil, old paints and other contaminants. The joints between the panels must be treated and sealed with suitable materials. After the surface is properly prepared, it is primed with the one-component polyurethane primer PRIMER-PU 100 or the two-component polyurethane PRIMER-PU 140. The primer should be applied uniformly over the entire surface using a brush, roller or spray gun, with a consumption of approx. 200 g/m2. ISOMAT-PUA 1360 may be applied 2-3 hours (depending on the weather conditions) after the application of the polyurethane primer and while the surface is still tacky. In any case, the waiting time after the application of the primer should not exceed 24 hours.

Metal surface
The substrate is prepared by brushing, rubbing, sandblasting, etc. and is then thoroughly cleaned using an industrial vacuum cleaner to ensure the surface is dry, stable and free from materials that may inhibit adhesion, such as dust, loose material, oil, rust or corrosion of any type. Then, the two-component, anti-corrosion epoxy primer EPOXYCOAT-AC is applied with a brush, roller or by spray in two layers. The second layer may be applied as soon as the first one has dried. ISOMAT-PUA 1360 is applied within 24 h from priming.

Application – Consumption
Components A and B are packaged in separate containers. Polyurea membrane is applied using a special high pressure and high temperature spray gun. The application temperature of the two components has to range between 75-85 oC and pressure must be set between 160-200 bar. ISOMAT-PUA 1360 is sprayed after the primer has dried (depending on the temperature and humidity conditions, as well as the selected primer). Consumption: approx. 1.0 kg/m2/mm, depending on the substrate.

  • Substrate temperature must be at least 3 oC above the dew point in order to avoid the risk of vapor condensation.
  • Especially for component A (isocyanate), exposure to temperatures below 5 oC during transport or storage can cause increase of the viscosity or even crystallization (in case of extremely low temperatures), depending on the time of the exposure and the minimum temperature at which the material was exposed. The process is reversible (by storing the material at room temperature and waiting for the viscosity to return to normal before application) and does not affect the properties and performance of the material.
  • The applied membrane is sensitive to UV radiation, so discoloration is possible during exposure. In that case, to ensure the properties of ISOMAT-PUA 1360 remain intact, it is recommended to protect the final surface with the one-component, aliphatic, elastic, polyurethane protective coating TOPCOAT-PU 720 is applied by brush, roller or spray within 24 hours from the application of the polyurea.
  • ISOMAt-PUA 1360 is intended for professional use only.
