Abstract

An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120° F. and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate, or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100° F. and having an API gravity at 60° F. from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.

Claims (10)

1. A method for preparing a solid anti-seize composition comprising:

selecting a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm;

selecting a naphthenic petroleum oil with a viscosity of less than about 300 SUS at 100° F. and an API gravity at 60° F. from about 23 to about 25;

mixing said grease and said oil to form a combined oil/grease composition;

adding and mixing into said oil/grease composition (a) a solid anti-seize lubricant; and (b) a polymeric matrix to form said solid anti-seize composition.

2. The method of claim 1 , further comprising:

heating said matrix material or said oil/grease composition to a temperature from about 80° C. to about 100° C.;

maintaining said anti-seize composition at the temperature of about 80° C. to about 100° C. while mixing;

adding said solid anti-seize composition at the temperature of about 80° C. to about 100° C. into a dispensing container having a generally elongate hollow body and having first and second ends, with one of said ends defining a dispense bottom to releasably hold the composition; and

cooling said composition to room temperature to solidify said composition.
