Product Description
AMSOIL Dipping Rust Preventive (DRP) is an oil/solvent
based water deplacing rust preventive. Its barium-free,
non-emulsified, alkali-resistant formulation is particularly
effective at deplacing water from metal parts after machining
or alkali cleaning. AMSOIL DRP provides outstanding rust
preventive performance by providing a protective
non-staining film after solvent evaporation.
AMSOIL DRP can be applied by any means including spray,
brush, dip or automatic applicator system. DRP has passed
the severe requirements of the ASTM D-665A (fresh water),
D-665B (synthetic seawater) and D-1748 (humidity cabinet)
rust tests. These tests have demonstrated that DRP provides
excellent rust protection in the harshest environments.
DRP also provides moderate lubricating qualities where it
may be desirable. When applied, DRP will leave a thin film
residue on the surfaces to protect the metal, yet it will not
gum up or dry off the surfaces. DRP has a rust protection service
life of over six months when parts are subject to the
open atmosphere and a service life of several years when
the parts are wrapped or sealed in plastic and not subject
to environmental elements. DRP is excellent for use on sheet steel, galvanized steel, aluminum
(to help prevent white oxide corrosion), hand tools,
packaged parts or anywhere rust protection is desired.
Safety Summary
DRP is non-toxic and is easily handled. However, as with any
chemical product, extended skin exposure can lead to redness,
irritations, rash, itching, etc. It is recommended that eye
protection and rubber gloves be used when handling this
product

Summary Of Rust Test Methods
Water and synthetic seawater — A mixture of 300 ml of
the oil under test is stirred with 30 ml of distilled water or synthetic
sea water, as required, at a temperature of 60°C
(140°F) with a cylindrical steel specimen completely
immersed therein. It is customary to run the test for 24
hours; however, the test period may, at the discretion of the
contracting parties, be for a shorter or longer period. The
specimen is observed for signs of rusting, and if desired,
degree of rusting.
Humidity cabinet — Steel panels are prepared to a prescribed
surface finish, dipped in the test oil, allowed to
drain and then suspended in a humidity cabinet at 48.9 ± °C
(120°F) for a specified number of hours. The oil fails or
passes the test according to the size and number of rust dots
on the test surfaces of the panels.
