Pure Polyurea Coating Technology
SpecPolyurea is a one coat hot spray applied elastomeric coating system capable of producing a seamless high strength & flexible membrane typically applied onto concrete or steel substrates. It can also be applied onto wood, asphalt & polystyrene with the correct priming system. A coating system that can be used for a wide variety of applications.
Polyurea has numerous advantages over conventional materials due to their rapid setting time, high elongation, tensile strength, durability & abrasion resistant charateristics. Polyureas, compared to other polymer coatings, stand out because of their versatility, longevity and strength.
SpecPolyurea is a two component pure polyurea coating that comes as 100% solids.
Characteristics of polyurea coating systems
- Thermal Resistance/ Thermally Stable To 150°C.
- Resistance to atmospheric attack.
- Moisture insensitivity.
- Fast reaction time.
- High abrasion resistance.
- High chemical resistance.
- Superior tensile & structural strength.
- Impact resistant.

SpecPolyurea For Acid & Chemical Resistance Applications
Applications below are related to hazardous chemicals, acids & oil / petroluem. When dealing with hazardous chemicals, acids & oil / petroluem; having effective containment & management solutions are critical to ensuring no personnel get injured or affected by the material being handled. SpecPolyurea is a preferred choice for containment, spillage and exposure in the following applications:
Tank Linings | Pipeline Coatings | Reservoir Linings | Lining Of Sewage Digestors | Uranium Mine Yellowcake Thickeners plus Ore Processing
Backup System For Spillage | Spill Berms | Containment Booms
Industrial Site Flooring
Areas Where Spillage May Occur | Drum & Flow Bin Storage Facilities
Water Towers | Reservoir Roofs | Leak Proof barriers | Sealing Steel, Concrete Tanks & Structures
Facilities & Refineries
Material Handling Areas | Production & Processing Facilities
Diaphragm Pump Bodies | Sewage Agitators | Vacuum Pump Castings | Submersible Motor Pumps

|SpecPolyurea 1000 Pure Polyurea - Soft/Flexible||70||25||15||42||620||13||20||65|
|SpecPolyurea 3000 Pure Polyurea - High Strength||92||45||21||75||400||3||5||65|
|SpecPolyurea 5000 Pure Polyurea - Very High Strength||98||65||21||120||200||8||20||65|
Our SpecPolyurea can be used outdoors & indoors; but as with all aromatic polyurea coatings, discolouration upon exterior exposure is common. These effects can be masked by using black polyurea or overcoating the polyurea with an aliphatic coating such as SpecSpartic Polyaspartic, PU DTM Flexi HB, PU 55 HB DTM Gloss or Glazetek within the set out overcoating window.
Our SpecPolyurea is applied using plural component spray equipment with a 1:1 direct impingement at a temperature of 70°C.
The coating cures within seconds allowing for rapid return to service and is relatively moisture & temperature insensitive allowing extended working seasons & application in relatively extreme conditions where high humidity exists.
