The steel pipe was sprayed in April, 2015. It is located in Yantai city, Shandong province. We sprayed our 100% pure polyurea product for the pipe. Our pure polyurea coating has achieved very good corrosion resistance, protective and appearance effects.
Our Qtech polyurea serious products are invented by Qingdao Shamu Advanced Material Co., Ltd. and Institute of Functional Material in Qingdao University of Technology and it performance has been the top of in China and leading worldwide in its similar category polyurea.
Polyurea Applications
Pure polyurea material has excellent waterproof, anti-corrosion and anti-abrasion properties. The polyurea coating has no joint and smooth appearance.
Pure polyurea is widely used in different kinds of projects, especially suitable for:
1. Waterproofing projects: high-speed railway, tunnel, sports buildings, roof, underground, pool, water conservancy project, etc.
2. Anti-corrosion projects: exterior & interior pipe line/storage tank, oil pipeline, etc.
3. Wearing resistant projects: ocean projects, industrial flooring, film and television properties, industrial and civil construction etc.
Polyurea can also be applied over a variety of different substrate (concrete, metals, wood and more) in a wide range of temperature and humidity environments.In addition to fixed workshop locations, coating products can be sprayed any time, any place.
Polyurea Features
1. High reactivity and fast curing speed.
2. Not sensitive to temperature and humidity, even can be cured on the surface of the water and ice.
3. Excellent physical properties, such as high die performance, high tensile strength, high elongation, impact strength and so on.
4. It does not contain any volatile organic compounds (VOC), is environmentally friendly, and is non-toxic, odorless and non-polluting.
5. Excellent chemical resistance and decorative.
6. Good weather resistance and aging resistance.
Polyurea Coating Description
The polyurea elastomer is an elastomer formed by reacting an A component isocyanate with a B component amino mixed resin. The most basic characteristics are anti-corrosion, waterproof and wear-resistant.
A component may be an aromatic isocyanate or an aliphatic isocyanate. B component is composed of a terminal amino polyether and a terminal amino chain extender.
A/B component reacts to form a urea bond, and the structure of the urea bond is symmetrical, with stable characteristics and excellent bond energy, which makes the polyurea excellent in characteristics and very stable.
