Pre-applied adhesives and sealants

Henkel’s complete range of LOCTITE^® pre-applied coatings eliminate the need to apply liquid threadlockers and thread sealants, or any other mechanical locking or sealing device parts during manual or automatic assembly.

These dry-to-touch pre-applied threadlockers and thread sealants are applied to screws and bolts commonly used for automotive and other high-volume part applications. Customizable to meet specific customer applications, they are available with various strengths, temperature resistance ranges, and lubricating properties.

Henkel receives many customer requests for a LOCTITE^® pre-applied threadlocker equivalent to the performance of LOCTITE^® 242 or 243. Most often the correct crossover pre-applied threadlocker is either LOCTITE^® DRI 202 or LOCTITE^® DRI 2045. The correct product depends upon many factors (thread plating, needed temperature resistance, and bolt size to name but a few.) Please contact your Henkel representative with any questions or to confirm the best product for your application.

When an application requires higher breakloose torque augmentation- similar to either LOCTITE^® 262, 263, 268, 271, Henkel recommends evaluating LOCTITE^® DRI 201, 204, 205 or the new LOCTITE^® DRI 2250. The correct product depends upon many factors (thread plating, needed temperature resistance, and bolt size to name but a few.) Please contact your Henkel representative with any questions or to confirm the best product for your application.

All screws and fasteners coated with LOCTITE^® pre-applied patches are designed to provide both threadlocking and thread sealing benefits once the product is completely cured. LOCTITE^® pre-applied patches are designed for assemblies that are exposed to all levels of vibration and have been specified in the harshest of environments. 

These water-based pre-applied patches ensure that manufacturing, application, drying, and assembly processes are environmentally sustainable. Screws and fasteners coated with LOCTITE^® pre-applied patches can be reused after disassembly by cleaning the threads and then applying the appropriate liquid LOCTITE^® threadlocking or thread sealing product during reassembly.

Customers can use threaded parts coated with LOCTITE^®’s pre-applied thread sealant with the guarantee that the product is applied in the right location and correct amount. With a pre-applied thread sealant, there is no need to apply additional liquid sealants, Teflon^® tape, or any other sealing material during assembly. Thread fittings coated with LOCTITE^® Dri-Seal provide instant sealing up to 5,000 psi when dealing with tapered thread assemblies- or straight to tapered thread assemblies. When needing to seal pure straight thread assemblies the recommended pe-applied thread sealant is LOCTITE^® DRI STS.
