White Polyurethane Protective Coating for Railway Applications
ALTIC HR 100 PU WHITE FOR RAILWAY is a white polyurethane protective coating designed for suitable railway and transportation applications where a durable, uniform and weather-resistant finish is required.
The coating is intended to provide a protective surface layer while maintaining a clean white appearance. It can be incorporated into properly specified railway coating systems for suitable metal and previously prepared surfaces.
Key Features & Benefits
- White polyurethane protective finish
- Designed for suitable railway coating applications
- Provides a smooth and uniform appearance
- Helps protect surfaces against environmental exposure
- Supports long-term coating-system performance
- Suitable for maintenance and refurbishment applications
- Provides an attractive white finish for transportation assets
- Can be incorporated into compatible multi-coat coating systems
Recommended Applications
ALTIC HR 100 PU White for Railway can be considered for suitable railway and transportation components, including:
- Railway coaches
- Railway carriages
- Railway exterior metal surfaces
- Railway equipment and fabricated components
- Transportation structures
- Suitable metal panels and assemblies
- Railway maintenance and refurbishment projects
Application suitability should be confirmed against the specific railway specification and service requirements.
Surface Preparation
Correct surface preparation is essential for achieving good adhesion and coating performance.
Before application:
- Remove dust, dirt, grease, oil and other contaminants.
- Remove loose rust, scale and poorly bonded old coatings.
- Mechanically or abrasively prepare the substrate as required.
- Ensure the surface is clean and suitably dry.
- Apply the specified compatible primer system.
- Ensure the underlying coating is properly cured and suitable for the PU topcoat.
- Apply ALTIC HR 100 PU White according to the approved coating specification.
For previously painted railway surfaces, areas with damaged or poorly adhered coatings should be appropriately repaired before recoating.
Application Method
ALTIC HR 100 PU White should be mixed and applied according to the latest product Technical Data Sheet.
Depending on the approved system and application requirements, suitable application equipment may include:
- Air spray
- Airless spray
- Other approved application methods
Apply uniformly to achieve the specified finish and film thickness. Avoid excessive coating thickness or uneven application.
Allow the coating to dry and cure according to the specified recoat interval before applying additional coats or placing the asset into service.
Typical Railway Coating System
A railway protective coating system may generally consist of:
Surface Preparation → Primer → Intermediate/Base Coat → ALTIC HR 100 PU White
The exact primer, intermediate coating, number of coats, DFT, thinner, curing schedule and application conditions should be selected according to the applicable railway coating specification.
White Finish for Railway Assets
A white polyurethane topcoat can provide a clean and consistent appearance across railway coaches and other transportation assets. It can also serve as the final visible layer of a multi-coat protective system.
The final appearance depends on substrate preparation, primer compatibility, application equipment, environmental conditions, film thickness and curing.
Application Considerations
Before starting a railway coating project, verify:
- Approved substrate and coating system
- Existing coating compatibility
- Surface preparation requirements
- Primer and intermediate-coat compatibility
- Required dry film thickness
- Application method
- Recoat interval
- Drying and curing conditions
- Applicable railway/project specifications
For railway projects, the coating should be evaluated against the specific customer, railway authority or project specification rather than assuming general railway compliance.
Safety & Handling
Use appropriate personal protective equipment during preparation and application. Ensure adequate ventilation and follow the manufacturer’s Safety Data Sheet (SDS) for handling, storage, application and disposal.
