A new type of "universal" coating technology
 

The introduction

Polyurea is a type of compound produced by the reaction of isocyanate components and amino compounds. The isocyanate component can be a monomer, a polymer, an isocyanate derivative, a prepolymer, and a semi-prepolymer.

Polyurea is extremely versatile. Its application fields are distributed as follows: concrete protection accounts for 60%, truck wear-resistant lining accounts for 15%, steel structure anti-corrosion accounts for 10%, roof waterproofing accounts for 10%, and others account for 5%.

Polyurea is sprayed on site from raw materials such as semi-prepolymer, amino-terminated polyether, and amine chain extender. It is extremely hydrophobic and insensitive to environmental humidity. It can even be sprayed on water (or ice) to form a film. It can be constructed normally under extremely harsh environmental conditions, and its performance is particularly outstanding. The emergence of polyurea completely broke the traditional concept of anti-corrosion and protection and set a higher standard for the material protection industry. The polyurea coating is flexible, rigid, and colorful. It is dense, continuous, and seamless. It completely blocks the penetration of moisture and oxygen in the air and has unparalleled anti-corrosion and protective properties. It also has multiple functions, such as wear resistance, waterproofing, impact resistance, fatigue resistance, aging resistance, high-temperature resistance, nuclear radiation resistance, etc., so it has a wide range of applications. No wonder engineers find magical new uses for SPUA materials every day.

As a protective technology, polyurea technology is mainly used in four major fields: waterproofing, anti-corrosion, anti-abrasion, and surface decoration.

The Features

1. Our construction material stands out for its unique properties. It cures rapidly, without the need for catalysts. It can be applied to any surface, be it curved, inclined, or vertical, without sagging. It forms a gel in just 5 seconds and reaches walking strength in a mere 1 minute.

2. It is not sensitive to moisture and temperature and is not affected by ambient temperature and humidity during construction (it can be constructed at -28°C; it can be sprayed and cured on ice).

3. Our construction material is a two-component, 100% solid content solution. It's free from volatile organic compounds (VOCs), making it an environmentally friendly and pollution-free choice for construction. It's also safe for hygienic construction, ensuring the health and well-being of your workers.

4. Thermal spraying or pouring: the thickness of one construction can range from hundreds of microns to several centimeters, overcoming the shortcomings of multiple constructions in the past.

5. Excellent physical and chemical properties, high tensile impact strength, flexibility, wear resistance, anti-slip, aging, and corrosion resistance.

6. It has good thermal stability, can be used for a long time at 120℃, and can withstand short-term thermal shock of 350℃.

7. The prototype has good reproducibility; the coating is continuous and dense, with no seams and no pinholes, and beautiful, practical, and durable.

8. Our construction material is designed for efficiency. It comes with a complete set of equipment, making the construction process extremely efficient. It can achieve the required design thickness in a single construction time. The equipment is equipped with multiple switching modes, allowing for both spraying and pouring. Plus, the construction process control ensures an anti-slip effect, adding to its practicality and safety.

9. It has good adhesion and can be sprayed on any substrate, such as steel, wood, concrete, etc.

 

Spray Polyurea Elastomer

Spray Polyurea Elastomer (hereinafter referred to as SPUA) technology has been developed abroad in the past ten years, following the low (no) pollution coating technologies such as high solid coatings, water-based coatings, radiation curing coatings, powder coatings, etc., in order to adapt to environmental protection. A new solvent-free, pollution-free green construction technology developed based on the needs of the industry. It is developed on the basis of reaction injection molding (RIM) technology. Its main raw material is the amino-terminated amino acid first developed by the American company Texaco/Huntsman. Polyoxypropylene ether (amino-terminated polyether), the brand name is Jeffamine. This process is a fast-response spraying system. The raw material system does not contain solvents, has fast curing speed, and is simple in process. It can easily spray a coating of more than ten millimeters thick on facades and curved surfaces without sagging.

Spua Technology Application

 

SPUA technology is a new type of "universal" coating technology and is known as the greatest discovery in the field of coatings and coating technology at the end of the twentieth century. It combines new technologies, new materials, and new processes and is a revolutionary leap in traditional construction technology. It has been used in developed countries such as North America for more than ten years, and the market demand is very strong.

Spua Technology Application

 

SPUA technology comprehensively breaks through the limitations of traditional environmentally friendly painting technology. Therefore, the technology developed rapidly as soon as it came out.

At present, it has been increasingly recognized and accepted by people, and has attracted widespread attention and reverse around the world.twentieth century. It combines new technologies, new materials, and new processes and is a revolutionary leap in traditional construction technology. It has been used in developed countries such as North America for more than ten years, and the market demand is very strong.
