Claim:
Anti-seize composition comprising: a) a binder, including at least one of (i) a curable or cross-linkable monomer containing ethylenically unsaturated groups, (ii) 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, (iii) a physically setting polymer selected from poly(meth)acrylates, polyesters, polyamides, polyimides, polyurethanes, polycarbonates, polyvinylhalogens and copolymers thereof, or (iv) hydraulically setting inorganic substances, b) at least one microencapsulated substance which releases gases at elevated temperature, selected from the group consisting of azo compounds; hydrazine derivatives selected from the group consisting of 4,4′-oxybis(benzenesulfohydrazide), diphenyl sulfone-3,3-disulfohydrazide, diphenylene oxide-4,4′-disulfohydrazide, trihydrazinotriazine or p-tolylenesulfonyl semicarbazide; tetrazoles; benzoxazines; carboxlic acids and carboxylic acid derivatives selected from the group consisting of malonic acid, α-ketocarboxylic acids, β-ketocarboxylic acids, α,α,α-, trihalocarboxylic acids, glyceridecarboxylic acids, β-hydroxy carboxylic acids, β-lactones or carboxylic anhydrides; c) at least one friction-reducing additive, selected from graphites, metal sulfides, polyolefins and fluorinated polyolefins.
