Product Introduction

Introduction of Polyurethane Waterproofing Coating for Railway and Bridge:

Polyurethane Waterproofing Coating is an advanced, two-component waterproofing system built for use in railway and bridge construction. The high performance, elastomeric polyurethane topcoat is specifically designed to provide long-lasting protection against water, weathering and chemical corrosion, while maintaining its flexibility and durability over time.

Features and Advantages:

1. Outstanding Waterproofing Properties: Our polyurethane waterproofing coating has excellent water resistance properties, making it the ideal choice for railway and bridge construction. It effectively protects the structure from water ingress and prevents costly maintenance damage caused by exposure to water.

2. Anti-Corrosion Resistance: The Polyurethane Waterproofing Coating is highly resistant to chemical and atmospheric corrosion. It ensures that the structure remains stable and reduces the potential for maintenance expenses in the future.

3. Flexible and Durability: The advanced polyurethane material of the coating retains its flexibility and cyclic crack bridging characteristics, ensuring that the structure stays safe and secure in its long run.

4. Enhanced Adhesion: The coating also offers excellent adhesion properties, which help to provide a tight, strong bond between the substrate and the coating. This creates unbeatable protection against weathering and other structural damages.

Application:

The Polyurethane Waterproofing Coating is suitable for a variety of railway and bridge applications. It can be applied over a broad range of structural substrates, including concrete, metal, and other building materials, ensuring water-resistance and long-lasting durability. The coating can also be applied to steel bridges, structural steel, concrete bridges, and railroad ties.

Construction Process:

The application of Polyurethane Waterproofing Coating follows a comprehensive construction process. Firstly, the surface where the coating will be applied must be cleaned and prepared. Secondly, the primer is applied to help create a strong bond between the surface and the coating. Finally, the polyurethane topcoat is applied to seal off and protect the entire structure.

Conclusion:

In summary, Polyurethane Waterproofing Coating is the optimal system for the protection of railway and bridge structures against water and corrosion. It provides excellent waterproofing, anti-corrosion, flexibility, durability, and adhesion properties, making it the ideal choice for a range of applications. Our unique construction process guarantees the long-lasting performance of the coating to the highest standards.

Technical Data Sheet

No.	Item	Standard Index	Test Method
1	Solid Content	＞90%	ASTM C836
2	Tensile Strength	＞2.0MPa	ASTM D412, 16 method A
3	Elongation at break	＞500%	ASTM D412, 16 method A
4	Peel Adhesion to Concrete	＞2 N/mm	ASTM D 903-98

Note:

1. Seal immediately after it is opened, to prevent moisture absorption solidification and scrap. It is recommended to use up once opened.

2. The film is not allowed to expose the bottom, drum, fall off, cracking and closed lax phenomenon.

3. If storage period is longer, it will form a thin glue in the surface. Remove the glue when using it, which does not affect coating quality.

Storage and Transportation

This product should be stored in a cool and ventilated place, not close to the fire source. During the transportation, keep the package intact to prevent collision.
