Polyurethane Products
Polyurea
Polyurea is a two-component material comprising Component A and Component B. The primary component of Component A is isocyanate prepolymer, while Component B is formulated with amino compounds as raw materials. It does not contain catalysts, cures rapidly, can be sprayed and formed on any curved, sloping, or vertical surface without sagging. It does not exhibit dripping phenomena, gels in 45 seconds, and achieves fixed strength in just 1 minute.

Product Features
- Insensitive to humidity and temperature, the application is not affected by environmental conditions such as temperature and humidity (can be applied at -28°C; can be sprayed and cured on ice).
- Two-component, 100% solid content, free of any volatile organic compounds (VOC), environmentally friendly, pollution-free construction, safe for sanitary construction.
- Excellent physical and chemical properties, with high tensile and impact strength, flexibility, abrasion resistance, anti-slip properties, aging resistance, and corrosion resistance.
- Good thermal stability, suitable for long-term use at 80°C.
- Good reproducibility, with a continuous, dense coating, no seams, no pinholes, aesthetically pleasing, practical, and durable.
- Applied using specialized spray equipment, high efficiency; the equipment is equipped with various switching modes, allowing both spraying and pouring. The anti-slip effect can be achieved through construction processes.
- Has good adhesion and can be sprayed on steel, wood, concrete, and any other substrate.

Construction Parameters and Conditions
| Surface Treatment | Spray directly on the primer or intermediate coat |
| Mixing Ratio (by weight) | The customer must thoroughly mix before use. Polyurea Component A: Polyurea Component B = 1.1:1 (packing ratio) |
| Theoretical Coverage rate | For a dry coating with a thickness of 1mm, spraying requires 1.5 Kg/m² |
| Cleaning Agent | Specialized diluent |
| Drying Time | Gel time less than 20 seconds |
Construction Conditions:
- Painting environment temperature range: 5 to 35°C. The substrate temperature should be at least 5°C higher than the air dew point temperature.
- Painting environment humidity range: 30 to 80%.
- Ventilation conditions: Ensure that the construction site is well-ventilated and free of dust.
Construction Method:
Spraying, using specialized equipment.
Application
Rigid polyurea is suitable for applications in petroleum, petrochemical pipelines, municipal gas pipelines, and various types of steel chemical storage tanks.
Precautions for Use
- The material should be stored in a dry, cool, and well-ventilated area, avoiding high temperatures and ignition sources.
- Before use, carefully read the construction instructions and warning labels on the packaging container.
- Must be used in well-ventilated conditions. Open flames are prohibited at the construction site, including activities such as welding, grinding, smoking, and other unspecified situations.
- When working with the material, wear a respiratory mask and other protective equipment. Avoid inhaling paint fumes and prevent skin contact with the coating. If the material comes into contact with the skin, wash immediately with an appropriate cleanser, soap, and plenty of water. In case of splashing into the eyes, rinse thoroughly with water and seek immediate medical attention.
