The appearance of polyurea coating has broken the situation that epoxy, acrylic and polyurethane are all in the world in the field of coating protection, and provided a very advanced and practical technology for the engineering field. Especially its tolerance to high moisture and high humidity environment is highly praised by outdoor constructors, so it can be widely used in large-scale infrastructure projects at home and abroad. In recent years, many key infrastructure projects in China have selected polyurea coatings.
Introduction of polyurea waterproof material
Polyurea machine spraying technology is a new solvent-free and pollution-free green construction technology developed in recent 20 years to meet the requirements of environmental protection. Its main characteristics are as follows:
(1) The coating does not contain catalyst, fast curing, can be spray formed on any curved surface, inclined surface and vertical surface, without sagging phenomenon, 5S gel, 1 min can reach walking strength.
(2) The coating is not sensitive to moisture and humidity, and is not affected by the ambient temperature and humidity during construction.
(3) The coating is 100% solid content, free of any volatile organic compounds (VOC), environmentally friendly.
(4) It has excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, corrosion resistance, etc.
(5) It has good thermal stability, can be used at 120 ℃ for a long time, and can withstand 150 ℃ for a short time.
