LOCTITE® DRI 2250-W™ is a medium to high strength
pre-applied threadlocker with good adhesion to a variety of
fastener finishes, specially designed to meet automotive
specification requirements. It is suitable for use on plain and
passivated metal surfaces. This product has good hot strength
and heat aging capabilities up to 220°C as well as good solvent
resistance properties. The pre-applied film is dry-to-the-touch
and remains an inert coating until assembly. During assembly
microcapsules, which are contained within the coating, are
crushed thereby releasing an active ingredient which initiates
the curing process. LOCTITE® DRI 2250-W™ prevents
loosening of threaded fasteners. When cured, this product will
also act as a thread sealant. It is particularly suitable in
situations where threaded parts are required to be ready for
immediate use in an adhesive joint in a high volume production
environment where it may not be possible to apply a liquid
product on line.
