New material POR-15 in the field of anti-corrosion

Corrosion and rust prevention are always a problem for people. The annual economic losses caused by corrosion in the world are about 700 billion U.S. dollars, which is about 6 times the sum of natural disasters such as earthquakes, floods, and typhoons, and accounts for 2 to 4% of the gross national product (GNP) of each country. Reducing corrosion losses is of great significance to building a conservation-minded society.

Corrosion hazards involve all walks of life. People are generally familiar with industrial corrosion of ships, automobiles, machinery and equipment, pipelines, steel structures, etc. Corrosion protection is also very prominent in high-tech fields such as electronic equipment and aerospace. In recent years, more and more attention has been paid to the anti-corrosion problem of concrete buildings, and anti-corrosion coatings have been found in the Inner Ring Elevated Bridge, Yangpu Bridge, and Donghai Bridge.

In fact, corrosion and rust prevention are closely related to our daily life. For example, corrosion of air-conditioning racks causes high-altitude falls, corrosion of balcony railings causes safety hazards, leakage of pipelines, etc. At present, the topic of building a conservation-minded society has been known to everyone.

Mr. Zhang Yongding, former chairman and general manager of Shanghai Huili Group Co., Ltd., withdrew from the leadership position of a large-scale state-owned enterprise, organized the Shanghai Yongli Real Estate Group, covering business areas such as real estate, building materials, finance, and chemical engineering. He also served as president and vice president of various industry associations such as the Shanghai Entrepreneurs Association, the Shanghai Chemical Industry Association, and the Shanghai Chemical Building Materials Industry Association, and he actively exerted the residual heat for the development of the chemical building materials industry. After many overseas inspections, with his decades of practical experience and unremitting exploration of new materials, in 2005 he introduced a new type of anti-corrosion material in the United States - POR-15 series of anti-corrosion coatings to the country. At present, Shanghai Bolun Specialty Coatings Co., Ltd. has obtained the exclusive distribution authorization for the United States POR-15 company in China.

POR-15 series anti-corrosion coating is a high-performance new polyurethane anti-corrosion paint developed by POR-15 company in the late 1970s. It consists of a primer, a variety of finishes, a high-temperature paint, various metal surface treatment agents, and bonding. A complete anti-corrosion system consisting of an agent, a repair cream, etc. It is the best anti-corrosion agent for metal, non-metal (concrete, wood, fiberglass, etc.). Early application in aerospace and military industry. In recent years, it has been promoted to the overseas markets in chemical and metallurgy, oil and gas exploration, automotive, shipbuilding, road and bridge, industrial machinery, sewage treatment, industrial floors and other industrial and civil areas. It is in Buckingham Palace Square in the United Kingdom. , South Korea’s Samsung Electronics, Hong Kong Disneyland, Singapore’s Hajima and many other projects. POR-15 is called "permanent rust prevention" overseas.

POR-15 series anti-corrosion coatings entered China in 2005. Its excellent anti-corrosion performance, rust-operating characteristics, non-toxic and environmental-friendly quality, and high cost performance have attracted attention in the industry. In early 2006, it was listed as an application by the Jiangsu Academy of Transportation Sciences. Invention project. At present, it has been applied in important projects such as chemical industry parks, petrochemicals, power generation, international airport environmental protection equipment, highway bridges and guardrails, and has achieved good anti-corrosion and anti-rust effects. POR-15 series anti-corrosion coatings have also been popularized and applied in some civil projects in China, such as the steel structure landscape of residential quarters, balcony guardrails, and flat-sloped slope projects, prolonging the service life and improving the landscape effect.

POR-15 is distinguished from other advanced anti-corrosion coating technology in that the film is not microporous after the film is formed. Therefore, water, oxygen, and chemical corrosion to metals are completely eliminated. Other anticorrosive coatings can only be covered by multi-layer coating. Thick film to reduce capillary pores and delay corrosion.

POR-15 primer can be rusted, it does not require sand blasting depth rust removal, just to remove the floating rust, it will produce a chemical reaction with the rusted metal surface and form a "multi-finger grip." In addition, it greatly reduces the cost of manual operations and improves operating conditions.

The adhesion (bond strength) of POR-15 to steel reaches 24.9 MPa, while other anti-corrosion coatings generally do not exceed 10 MPa. Usually only 4Mpa strength is needed for concrete adhesion and concrete damage. The level of adhesion of anti-corrosion coating is one of the important indicators for judging the anti-corrosion performance. POR-15 coated on the steel plate can be punched and folded, the paint film does not peel off. Applied on the chassis of the car to prevent the stones from hitting without leaving marks.

POR-15 can withstand high temperature of 315°C, and can be topcoat and repair material that can withstand temperatures of 760°C and 1200°C. In the high-temperature pipeline, industrial furnace anti-corrosion rust fill the gaps. At present, the anticorrosive primers for domestic steel structures are not resistant to high temperatures, resulting in the peeling of the surface fire-retardant coating in the event of a fire and failing to meet the fire-resistance limit, which has been highly concerned by the industry.

POR-15 has excellent water resistance, oil resistance, acid resistance, alkali resistance and salt spray resistance, and is widely used in the chemical industry.

POR-15 high solids content. The coating rate is high, the coverage is good, the color is bright, and the aging resistance is excellent.

POR-15 film is tough, wear-resistant, non-slip, and anti-fouling. Suitable for industrial, garage and other floor coating.

POR-15 was tested by the Shanghai Entry-Exit Inspection and Quarantine Bureau for imported coatings and does not contain benzene or free toluene diisocyanate. Volatile organic compounds are much lower than China's limited standards. POR-15 is completely cured without any toxicity and is suitable for drinking water tank coating.

In the United States, POR-15 series products have also entered supermarket system sales and are loved by many DIY people. Do-it-yourself paint car chassis, battery brackets, paint garden mowers, guardrails. In the absence of electric welders, POR-15 adhesives can replace electric welding, iron and iron bonding, iron and concrete bonding are all extremely strong. The degreasing agent in POR-15 series products has a very good degreasing effect on the grease generated in daily life. The degreasing agent is completely non-toxic and environmentally friendly, and can even be used to wipe windows and clean collars. The product has entered China for nearly a year and has shown good market prospects.
