What are the characteristics of polyurea waterproof and anti-corrosion coatings? RLHY-1002 is an A, B two component, solvent free, fast curing anti-corrosion and waterproof coating. The coating is flexible, full of rigidity, rich in color, dense, continuous, seamless, and completely isolated from air and water and oxygen penetration on the ground. High reaction activity and fast curing speed: perpendicular to the surface, top surface, and any continuous spraying without flow suspension. Polyurea elastomers do not require catalysts and are not sensitive to temperature and humidity: they are less affected by environmental temperature and humidity during construction. Polyurea waterproof and anti-corrosion materials also have functions such as wear resistance, impact resistance, fatigue resistance, aging resistance, high temperature resistance, and nuclear radiation resistance.

With the development of high-speed railway construction in China, due to the particularity of high-speed railway construction, the performance requirements for waterproof materials are not only to deal with material cracking caused by thermal expansion and cold shrinkage of concrete or steel components, but also to have higher requirements for dynamic load capacity during heavy-duty operation of high-speed railways. Polyurea waterproof and anti-corrosion materials are required to have functions such as high strength, high elongation, high tear strength, high wear resistance, impact resistance, and aging resistance. Among many waterproof materials, polyurea may be a good choice. Therefore, polyurea is the main material for waterproofing coatings in high-speed railway construction in China.

With the rapid development of society, the waterproof and anti-corrosion properties of polyurea have also been discovered and applied, and "polyurea" will become a substitute for traditional resins in the 21st century. Polyurea has obvious performance advantages and is also known as a "high-end waterproof coating" in the industry, with a rapid growth trend every year. According to industry statistics, it is predicted that in the next few years or even ten years, the production of polyurea coatings will far exceed the production of traditional waterproof coatings. Polyurea waterproof and anti-corrosion coatings have become a new favorite in the waterproof industry due to their superior performance. Especially in recent years, waterproof repair engineering has gained favor from construction companies and gradually replaced some traditional materials. The main reason is that the polyurea waterproof and anti-corrosion coating has a long service life, oxidation resistance, and a wide range of applications.

The material with excellent waterproof effect is polyurea waterproof and anti-corrosion coating. Polyurea coatings have changed traditional waterproof coatings. Polyurea has the characteristics of instantaneous solidification and high-speed reaction. The coating is dense, continuous, and seamless, with outstanding protective performance; The combination of materials and waterproofing greatly improves the quality and progress of the project; Minimize the impact of weather on construction progress to a large extent; Good weather resistance and aging resistance to prevent mold growth. The polyurea waterproof and anti-corrosion material is super compressive and has no powder composite cracking under long-term ultraviolet radiation. It has reverse osmosis function, strong permeability, and can penetrate the interior of the wall without cracking. It can be used for a long time and fully achieve the waterproof effect on the back, with a service life of over 30 years.

Moreover, polyurea waterproof and anti-corrosion materials themselves have many performance characteristics, and their application fields are distributed as follows: concrete protection accounts for 55%, truck wear-resistant lining accounts for 15%, steel structure anti-corrosion accounts for 10%, roof waterproofing accounts for 15%, and others account for 5%. The proportion of roof waterproofing is not low, mainly used for waterproofing construction of building walls and roofs. The roof waterproofing adopts polyurea waterproof and anti-corrosion coating, which is completely impermeable and non leaking, effectively resisting external rainwater, as its own characteristics are impermeable.
