The durability of bonded components is especially important when dealing with large numbers of daily commuters and travelers. At the forefront of innovative design, trains and carriages need to offer long-term, consistent reliability, safety, and optimal operational performance.
When using Plexus methacrylate structural adhesives, manufacturers can assemble sub-components quickly and efficiently when applying modular and piece assembly methods to production. Removing the need for mechanical fasteners can provide manufacturers with lower weight solutions and increased design freedom.
Plexus methacrylate structural adhesives have the ability to bond multiple types of plastics, metals and composites, helping to lower component costs or improve safety, which is invaluable to the rail industry. Plexus methacrylate structural adhesives are used from design to assembly, ensuring structural and secondary components remain intact and resistant to dynamic environmental stresses. Our unique adhesives offer distinct advantages when dealing with complex components and large surface areas.
Plexus methacrylate structural adhesives MA300, MA310, MA420, and MA832 comply with R1 requirements for Hazard Levels HL1 – HL3, across all design and operational categories of rail vehicles.
R1/ Part 2 of EN45545-2:2013 standard for:
- Toxicity – EN45545 Annex C (ISO 5659)
- Flammability (ISO 5658-2)
- Heat Release (ISO 5660-2)

PRODUCT BENEFITS INCLUDE:
- UV stable
- Reduced VOC emissions
