Patent ID: 7260889

Claim:
A method of disassembling a socket/pin connection or threaded connection sealed or locked with a set anti-seize composition comprising: a) at least one binder selected from the group consisting of a1) a curable or cross-linkable monomer containing ethylenically unsaturated groups, a2) a curable or cross-linkable polymer or copolymer having chemically reacting groups and being selected from (meth)acrylic resins, epoxy resins, polyurethanes, unsaturated polyesters, polysulfides and silicones, a3) a physically setting polymer selected from poly(meth)acrylates, polyesters, polyamides, polyimides, polyurethanes, polycarbonates, polyvinylhalides and copolymers thereof, and a4) hydraulically setting inorganic substances, b) at least one substance which releases gases at elevated temperature to produce foam structures or porous structures which permit disassembling or tightening said connection, selected from the group consisting of azo compounds, hydrazine derivatives, carboxylic acid and carboxylic acid derivatives, organic peroxo compounds, inorganic carbonates, inorganic hydrogen carbonates and explosive substances, c) at least one friction-reducing additive selected from the group consisting of graphite, metal sulfides, polyolefines and fluorinated polyolefins, which comprises exposing said connection at least in part to a temperature at which component (b) releases gases, maintaining the temperature for a period sufficient to reduce the cohesive and, if appropriate, adhesive strength of the set anti-seize composition and disassembling or tightening said connection.
