Spray Polyurea waterproof coating/two part Polyurea anti-corrosion coating
1.Description
The coating system consists of amine-terminated polyether resin, amine chain extender and MDI prepolymer, functional filler is added, and the product belongs to spraying, self-cured and thick coated polyurea. It is used together with ground coat paint and facing coating to form a firm, tough and decorative ground protection system.
2.Feature
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 propertieslike 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 appliedwith 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 thicknessin one pass.
Good adhesionto a variety of different substrates (concrete, metals, wood etc.) even under high humidity and extreme temperatures.
3. Where to apply?
As a non exposed waterproofing layer in flat roofs, balconies and terraces, metal roofs or metal bridges, water tanks, wastewater and biological wastewater treatment tanks, settling tanks, swimming pools, aquariums etc.
As an elastomeric protective coating on industrial floors, in warehouses, recreation areas, craft businesses, car parks and traffic areas, auto repair shops, truck trailers etc.
Suitable for industrial refrigerators and areas subject to extremely low temperatures or large temperature variations.
Suitable for waterproofing and protecting polyurethane foam.
