Dow Corning offers a line of Molykote thread pastes that outperform conventional lubricants. The pastes include high-purity grades compatible with metals as well as metal-free and general purpose varieties. Molykote P-37 is an ultra-pure, high-temperature anti-seize lubricant for applications up to 1400°C, while Molykote P-40 is a metal-free lubricant offering adhesion in corrosive environments from -40 to 230°C. Molykote 1000 provides stable lubrication from -40 to 1150°C for threaded fasteners and prevents bolt seizure in severe conditions.

1. Thread Lubricating Pastes From Dow Corning
Outperform Conventional Products
Molykote® Brand Thread Pastes Offered in High-Purity, Metal-Free, General Lubricating Grades
A line of lubricating thread pastes offering unique properties for applications where conventional pastes cannot perform
is available from Dow Corning Corporation. Marketed under the Molykote® brand name, the product line includes
high-purity thread pastes that are compatible with metal alloys, as well as metal-free and general purpose pastes that are
safe for worker exposure and the environment.
Molykote® P-37 thread paste is an ultra-pure, high-temperature anti-seize lubricant formulated to protect bolts from
stress-corrosion cracking at temperatures up to 1400°C (2550°F). It offers excellent lubricity and high-load carrying
capability for damage-free assembly and disassembly. Unlike most competitive products, the formulation contains
extremely low levels of sulfur and halogens that can cause bolt fracture due to stress corrosion cracking. In addition,
these pastes contain no metal powders, which eliminate the possibility for solder embrittlement and/or galvanic
corrosion. Molykote P-37 is particularly suited for use in power plant operations (gas, fossil, nuclear steam turbines, and
flight turbines of aircrafts). Automotive applications include high temperature threaded connections such as those found
on exhaust pipes and catalytic converters. It is compatible with stainless steel, nimonic steel, and other nonferrous
metals, and is environmentally safe compared with pastes containing lead or nickel powders. Molykote® P-37 paste is
safer for operator exposure because the formulation is based on zirconium oxide and other non-hazardous solid
lubricants, which makes it virtually non-toxic.
Molykote® P-40 thread paste is a metal-free lubricant offering excellent adhesion to machine components that are
exposed to corrosive environments and extreme temperatures. It is a synthetic oil-based paste that contains proprietary
solid lubricants and corrosion inhibitors and is formulated without the use of metal powders. As a paste, it provides
continuous lubrication from -40 to 230oC (-40 to 446oF) and as a dry lubricant up to 1200oC (2192oF). Molykote P-40
paste eliminates problems associated with most competitive products that enhance their load carrying and high-
temperature capabilities by adding metal powders such as copper, nickel or aluminum. At elevated temperatures, for
example, the base oils in these pastes evaporate and leave only pure heavy metal powders that are known environmental
hazards. And, in some cases, the metal powders also pose severe safety risks due to the potential for ignition at high
temperatures and/or inhalation. The excellent adhesion and anti-corrosive properties offered by Molykote P-40
contribute to longer operating life and increased performance over competitive products. It is particularly suited for
applications exposed to corrosive splash water and humidity; and the lubrication of oscillating or vibrating machine
components, plain bearings, and sliding surfaces.
Molykote® 1000 thread paste is a general-purpose lubricant offering a unique combination of performance properties
that are not available from most competitive alternatives such as extreme temperature capabilities and unchanged
torque/tension properties for fasteners—even after repeated loosening and tightening cycles. This paste provides stable
lubrication of threaded fasteners and it is designed to prevent bolt seizure resulting from continuous exposure to
temperatures ranging from -40 to 1150oC (-40 to 2100oF).
Molykote® 1000 paste is formulated to have a coefficient of friction similar to mineral oil, which reduces the risk of
over-tightening threaded fasteners. This paste is typically suited for the lubrication of threaded connections exposed to
severe environments such as oven chains; exhaust manifold bolts, marine and outdoor equipment etc, and is an excellent
plant maintenance product for general use.
