Spray Polyurea Elastic Waterproof Coating
1. Introduction
This product is a double-component coating. A component is isocyanate compounds; B component is amine compounds. Construction technology is applied by spraying to mix the two components, generating the elastic waterproof coating.
2. Characteristics
- High active and fast set.
- Solid content, no volatilization of organics, nontoxic, environmental friendly.
- Have great strengthened adhesion and nonmetal materials, such as steel, aluminum, concrete, timber, glass fiber reinforced plastic and polyurethane froth.
- It is insensitive to the temperature and the humidity.
- It is steady in both low temperature and the high temperature.
- Good weathering resistance and aging resistance.
- Excellent physical property.
- Outstanding function in waterproofing, decoration, anticorrosion, and anti-slip.
- Use the complete set of equipment to spray.
- Produce different colors according to the requirements.
3. Applications
It is widely used in all kinds of waterproof anti-corrosion projects, especially suitable for the following projects.
* Waterproofing projects: high-speed railway, tunnel, concrete road, bridge, airplane parking, etc.
* Industry and civil construction: roof waterproofing projects, etc.
* Underground waterproofing and moisture−proofing projects: industrial and civil construction, indoor swimming pools, etc.
* Government projects: subway, landfill, sewage farm, etc.
* Anti-corrosion projects: water conservancy, etc.

5. Attention
- It is supposed to be sealed and stored upside down in a cool and dry place, avoiding direct sun exposure and humidity.
- During storage, there would be buildups on its surface. Just get rid of the buildups before application.
- Unspent coating is supposed to be sealed timely in case of curing and abandoned.
- During and after the process of waterproof construction, protect it timely, preventing from artificial damage.
- The storehouse or construction site should be kept away from fire. In the process of construction, workers should wear protective clothing.
- Storage time is 6 months. If it is qualified enough beyond storage time, it can still be put into use.
