product description

 

The spray polyurea waterproof coating is an elastomer waterproof coating prepared by mixing and reacting two components with an isocyanate compound as the A component and an amine compound as the B component.

 


 

Features

 

It has high reactivity and fast curing speed. It can be sprayed on any curved surface, inclined surface and vertical surface without sag. It takes 5 seconds to gel and reach walking strength in 1 minute.

 

The solid content is high, the whole set of equipment is sprayed, and the design thickness can be achieved by one spray, and the efficiency is extremely high, overcoming the drawbacks of repeated brushing in the past.

 

It has strong adhesion to all kinds of base layers (including concrete, metal, glass, wood, polyurethane foam board, etc.).

 

It is not sensitive to temperature and humidity, and is less affected by the environment during construction.

 

Good weather resistance, aging resistance, high temperature stability, long-term use at 120 °C, can withstand short-term thermal shock of 350 °C.

 

Excellent basic physicochemical properties, such as tensile strength, tear strength, impact strength, adhesion, low temperature toughness, dielectric strength, elongation, wear resistance, etc.

 

The coating is continuous, dense, seamless, and has no pinholes. It can be added with various pigments and fillers to make coatings of different colors and functions. It is waterproof, decorative, anti-corrosive and anti-slipper, and is beautiful and practical.

 

The use of complete sets of equipment for spraying, convenient construction, high efficiency, one-time construction can meet the design thickness requirements, to overcome the drawbacks of the previous multiple brushing.

Scope of application

 

 

It can be widely used in various fields and types of waterproof and anti-corrosion engineering, and is most suitable for the following types of projects:

 

The bridge deck of high-speed railways, tunnels and concrete paved roads is waterproof.

 

Waterproof, moisture-proof, and structures such as indoor swimming pools and fire fighting pools for underground construction of industrial and civil buildings are waterproof.

 

Municipal works such as subways, sewage treatment plants, and landfills are waterproof.

 

Water canals, pools and other water conservancy facilities are waterproof and anticorrosive; sports fields, stadiums, runways are waterproof and anticorrosive; industrial storage tanks and large components are waterproof and anticorrosive.

 

Wear-resistant waterproof layer for bridges, aprons, industrial floors, parking lots, etc.
