Henkel has introduced a breakthrough product to its comprehensive range of automotive pre-applied threadlocker coatings that brings the high-speed throughput of a flowable product with the sustainability advantages of a water-based material. The first ever water-based flowable pre-applied threadlocker, Loctite DRI 2250-W, is 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.”
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 coating until assembly. During assembly, microcapsules contained within the coating 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.
