Rail

Solutions for Removing Dirt, Grease, Machine Oil, Metal Chips, Paint, Rust and Other Tough Soils

Henkel is a leading supplier of state-of-the-art metal pretreatment technologies for steel, iron, light metals, and plastics. Henkel sets high standards for cleaning, corrosion protection, paint adhesion, and environmental safety. The products that make up the BONDERITE® brand include: process line chemistries; cleaners; pretreatment chemistries, including activators and conditioners; conversion coating chemistries; post-treatment chemistries, including rinses and passivation; as well as auxiliary products, such as toners, additives, accelerators and neutralizers.

Faster and Lower-Cost Assembly

From structural bonding to seam sealing and window glazing, we provide a complete range of technologies that allow you to reduce or replace traditional mechanical fastening and sealing methods in a variety of assembly applications. Water proofing to seal out water over the life of the vehicle is critical to performance. Henkel offers many sealant that are widely used for this purpose. One of the best solutions is to skip the creation of the hole and instead bond the structure together. We always ask designers to consider the following: "If you were designing a boat would you start by drilling 500 holes in the bottom"? Apply the same logic to the roof of your vehicle.

Bond joints eliminated the cost of drilling, rivet applications, allow dissimilar materials to be joined, distribute the load more evenly allowing lighter gage materials to be used, which all leads to strengthened vehicles with lower mass for efficiency gains.

From Weld and Fastener Reduction to Assembly of Dissimilar Substrates

For Use Between Flexible Sheet Metals, Rigid Castings/Extrusions, and/or Composite/Plastic Materials

Elastic Bonding has been used for decades in the rail industry to join dissimilar structural materials. Primarily designed to replace welds, rivets and other mechanical fasteners in the body, paint or trim shops, our wide range of high strength structural adhesives enable the assembly of non-metallic substrates and open new perspectives of lightweight designs. Adhesives optimize acoustic performance and contribute to weight reduction. The distributed load an adhesive provides versus the stress concentrations of mechanical fastening allows thinner, lower weight panels to be implemented, reducing weight.

Bonding and Sealing Windows / Elastomeric Bonding

Pumpable High Strength Elastomers for Bonding and Sealing

Designed to bond windscreens and side windows to the train body, our wide range of window glazing adhesives simplify and improve the assembly process while improving torsional stiffness and vehicle safety. Based on the substrates, Henkel offers a variety of engineered products and primers that provide exceptional performance. These include products formulated to provide primerless adhesion and instant fixturing to products, with controlled and uniform curing.

Fill Gaps and Leak Paths

Seal In/Out Heat, Liquids, Solids and Gases; Improve Aesthetics

Designed to prevent leakage, our robust seam sealants work effectively on metals, plastics and composites, and can be applied during any phase of vehicle or component assembly. Our current seam sealant technologies include products that are paintable and resistant to paint cure processes.

• Products engineered to adhere to bare oily metals in the body shop
• Painted components in the paint and trim shop
• Room temperature cure applications exposed to direct sun, elements and weather

NVH and Protective Coatings Create Stronger and Quieter Equipment

Henkel’s solutions to reduce noise, vibration and harshness (NVH) were originally designed for automotive vehicle cabins and are now used in rail equipment manufacturing. Our TEROSON® brand NVH solutions and LOCTITE® brand adhesives and sealants help enhance material properties and minimize audible noises. Henkel is a leading source worldwide for NVH (noise, vibration and harshness) solutions. We provide advanced NVH technologies and comprehensive design and engineering support to our customers. Henkel has been an NVH partner with the top rail manufacturers for more than 20 years, and our expertise also helps equipment manufacturers create dimensionally stronger and quieter products. Our TEROSON® brand NVH solutions and LOCTITE® brand adhesives and sealants help enhance material properties and minimize audible noises.  

LOCTITE® anaerobic thread sealants prevent leakage of gases and liquids and are available in liquid form or as sealing cord. Designed for low pressure and high pressure applications, they fill the space between threaded parts and provide an instant, low pressure seal. When fully cured, they seal to the burst strength of most pipe systems.

LOCTITE® threadlockers dramatically increase the reliability of threaded assemblies. Available as liquid and semi-solid adhesives, LOCTITE® threadlockers are applied to the threads of a fastener and cure to a hard thermoset plastic when applied between metal surfaces. They cure in the absence of air and completely fill the gaps between mating threads to lock and seal threads and joints.

LOCTITE® anaerobic retaining compounds secure bearings, bushings and cylindrical parts into housings or onto shafts. They achieve maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they form a 100% contact between mating metal surfaces, eliminating the need for expensive replacement parts, time consuming machining or the use of mechanical methods.

LOCTITE® gasketing products are self-forming gaskets that provide a perfect seal between components, with maximum face-to-face contact, eliminating flange face corrosion. They form a low-pressure seal immediately on assembly and fully cure in 24 hours, providing a joint that will not shrink, crack or relax. They are available as anaerobic products for rigid flanges and silicone products for flexible flanges.
