Wearable Spraying Polyurea SPUA-90 AB Courts Sports Surface Flooring Athletic Running Track

Spray polyurea elastomer
 Polyurea has high reactivity and fast curing speed: vertical surface, top surface and any curved surface can be continuously sprayed without sag. No catalyst. 5 seconds of gel, walking strength can be achieved in 1 minute.
It is not sensitive to temperature and humidity, and can even be cured on the surface of the water and ice.
Two-component, 100% solid content: does not contain any volatile organic compounds (VOC), is environmentally friendly, non-toxic and non-polluting during construction and use, and is known as [green materials, green technology".
Excellent physical properties: such as high anti-wear performance, high tensile strength, super crush resistance, high elongation, flexibility, tear resistance, wear resistance, aging resistance, impact strength, anti-cathode peeling, Insulation strength, etc. In addition, it has excellent low temperature toughness and can be used at -45 ° C ~ 150 ° C for a long time.
The hardness can vary from soft rubber (Shao A30) to hard elastomer (Shao D75). It has the high strength of plastic and the high elasticity of rubber. Excellent adhesion, strong adhesion to metal, non-metallic substrates such as steel, aluminum, reinforced concrete, wood, fiberglass, polyurethane foam.
Excellent chemical resistance: It can withstand most corrosive media (long-term immersion of acid, alkali, salt and seawater), especially for long-term urethane physicochemical properties under high temperature concentrated alkali (NaOH 30%, temperature 90 °C). There will be no qualitative changes, and it is an excellent heavy-duty anti-corrosion material.
Weather resistance and aging resistance: Aliphatic polyurea is not affected by ultraviolet rays and is not easily yellowed.
Although the aromatic polyurea is yellowish, it has no powdering and cracking, and is resistant to the impact of cold and heat shock and the weather and frost. Outdoor use can reach 30 years - 50 years.

The construction speed is fast. One equipment needs to be operated by 3 to 4 people. It can be constructed more than 1000 square meters per day, which is 15 to 20 times of the traditional technology, which minimizes the impact of weather on the construction progress. The thickness of a single construction can range from hundreds of micrometers to several centimeters, overcoming the ills of previous constructions.
