Henkel Launches Water-based Flow Adhesive for Sustainable Automotive Applications Henkel launches water-based flowable pre-applied threadlocker adhesive, Loctite DRI 2250-W, a medium to high strength pre-applied threadlocker that has been created to meet automotive specification requirements.

Unlike competitor products that use toluene and other solvents, Loctite DRI 2250-W enables high-speed throughput similar to solvents but is water-based,” explains Rainer Schoenfeld, global market strategy director for exterior, powertrain, interior and chassis at Henkel. “This provides automotive OEMs and suppliers with a sustainable and more environmentally friendly choice that doesn’t compromise on performance.”

High-temperature Resistance


Loctite DRI 2250-W offers high-temperature resistance of over 200ºC and has excellent chemical resistance. Scott Simmons, business development manager, North America, describes how its superior high temperature resistance addresses customers’ frustrations with competing products: “Traditional products fail to maintain room temperature (RT) breakloose strength and can typically lose around 50 percent – and in some cases even more – of their strength at 150ºC. By contrast, DRI 2250-W maintains RT strength beyond 150ºC and in most cases can achieve this up to 200ºC.”

Further advantages of Loctite DRI 2250-W include its low coefficient of friction. Tested on multiple plating surfaces, the material maintains a coefficient of friction between 0.10 – 0.16. It also shows superior performance on all plating types, including the newer zinc-flake coating, with added lubricity.

As a pre-applied film, the threadlocker is dry-to-the-touch and remains an inert until assembly. During assembly, microcapsules contained within are crushed and release an active ingredient that initiates the anaerobic curing process. When cured, Loctite DRI 2250-W also acts as a thread sealant as well as a threadlocker. It eliminates the need to apply liquid sealants, adhesives, or any other mechanical locking or sealing device to threaded parts during manual or automatic assembly and is flow coatable for higher output speeds.

Areas of Applications


  • Transmission, gearbox, PTU – gearbox and transmission fasteners; oil pan & side cover fasteners
  • Differential / axle – case and cover fasteners
  • Engine – oil pan and cover fasteners – any critical fastener application
  • Others – seat fasteners; electronic fasteners – M2 and smaller; any critical fastener subject to high vibration to prevent loosening

Loctite DRI 2250-W has already proved its capabilities in a production environment with a major seat manufacturer. The company demanded a high level of fastener integrity during lifecycle testing but was experiencing inconsistent results with critical fasteners due to variances in the supply chain. Hence, they sought a pre-applied threadlocker that could overcome these inconsistencies, while also being able to work on contaminated zinc-flake plated fasteners.

Henkel’s Loctite DRI 2250-W was the ideal solution. This high performance pre-applied threadlocker performs equally well on all fastener types including stainless steel and zinc-flake plated fasteners – and critically works effectively on both clean and contaminated fasteners. It demonstrated consistent bolt clamp load across a broad service temperature range and high vibration loading, while also providing excellent performance with good serviceability across many different fastener sizes.

A Sustainable Choice


Loctite DRI 2250-W is a water-based product that ensures that manufacturing, application, drying, and assembly processes are environmentally sustainable.

Its water-based chemistry contains no solvents or halogen.
