Reliable Sealing for Public Transportation
Public transportation vehicles operate in demanding environments. Buses and railway coaches experience continuous vibration, temperature fluctuations, moisture, dust, cleaning chemicals, outdoor weather and frequent passenger use.
Every joint, panel, enclosure and interface needs to maintain its integrity throughout the vehicle's service life.
Redisil silicone sealants provide flexible and durable sealing solutions for selected applications in bus and railway coach manufacturing, assembly and maintenance.
From body joints and exterior panels to windows, electrical enclosures and interior assemblies, Redisil helps manufacturers create reliable seals designed to withstand movement and environmental exposure.
Reliable. Durable. Engineered for Performance.
Silicone Sealing Solutions for Public Transportation
Modern buses and railway coaches combine a wide range of materials including aluminium, steel, glass, composites, plastics and rubber.
These materials can experience different rates of expansion and contraction, while the vehicle itself is continuously exposed to vibration and mechanical movement.
A suitable silicone sealant can help maintain a flexible seal between compatible substrates while providing protection against moisture, dust and environmental exposure.
Redisil focuses on silicone sealing solutions for applications where flexibility, adhesion, weather resistance and long-term sealing performance are important.

For visible applications, product colour and final appearance can also be considered during product selection.
Sealing Challenges in Public Transportation
Vibration & Movement
Buses and railway coaches experience continuous vibration during operation.
Flexible silicone sealants can accommodate suitable joint movement and help maintain sealing integrity.
Thermal Expansion
Vehicles operate through changing temperatures.
Different materials can expand and contract at different rates. Flexible silicone helps accommodate movement between compatible substrates.
Moisture & Humidity
Rain, condensation, washing and humidity can expose vehicle assemblies to moisture.
Properly designed sealing can help reduce water ingress.
UV & Weather Exposure
Exterior components experience prolonged sunlight and changing weather conditions.
Weather-resistant silicone formulations can provide long-term environmental protection for suitable outdoor joints.
Multi-Material Assemblies
Public transport vehicles use combinations of aluminium, steel, glass, plastics, rubber and composites.
Redisil products offer different substrate compatibility profiles, allowing selection based on the actual assembly. Redisil NP Pro, for example, lists steel, aluminium, glass, plastics, rubber, ceramics and concrete among compatible substrates.
