In the past decade, the use of spray-applied polyurea coatings for protecting concrete, steel and other industrial substrates from the degrading effects of corrosion and abrasion has increased dramatically. This innovative new polymer coating technology is 100% solids, contains zero volatile content and it is generating an extremely fast gel time which is ideal for moist environments like those in the hydro-electric industry.

Description:

	Reaction of isocyanate with primary amine terminated polyethers
	Processed commercially available high pressure
	High temperature impingement mix spray equipment
	A two-component spray elastomeric and coating system, one component being the isocyanate quasiprepolymer and the other component being the resin blend.

Advantages:

	SPUA overcomes many shortcomings of traditional application technology and make a revolutionary leap for application in site.
	Excellent mechanical properties and extended durability, even in extreme environmental conditions.
	Fast, consistent reactivity that is hydrophobic and therefore affected very little by damp or cold surfaces. It can be sprayed directly on water or ice and has been sprayed at -20°C with minimal effect on tack free time. No catalysts are required.
	Excellent adhesion to a wide variety of substrates for properly formulated systems
	Readily compliant with regulations limiting the levels of volatile organic compounds.
	Polyurea spray elastomer systems are able to meet stringent environment standards due to the 100% solids formulations.
	Polyurea spray elastomer can be built up to any thickness in one application including vertical and overhead surfaces. It eliminates the sagging, the need for multi-coat applications.
	Polyurea spray elastomer is characterized with good weathering, abrasion resistance, chemical and water resistance, especially insensitivity to humidity.
