Self-lubricating compositions

A film-forming formulation for preventing insects from crossing or climbing the surface, the formulation comprising at least one film forming material, a mixture of fatty materials having a multiplicity of molecular weights and/or viscosities, and optionally a surfactant, wherein the formulation is optionally an aqueous formulation.

A method of preventing insects from crossing or climbing a surface, the method comprising forming a coating or a film on said surface, wherein said coating or film comprises a film-forming material, a mixture of fatty materials having a multiplicity of molecular weights or viscosities, and optionally a surfactant.

A surfactant in a form of an adduct formed of poly (hydroxymethylsiloxane) (PHMS) and polyethylene glycol (PEG), wherein the PHMS and the PEG are associated to each other via covalent bonds or via hydrogen bonding.

An object or an article of manufacture having at least a surface region thereof coated with a film comprising a film-forming material, a mixture of fatty materials having a multiplicity of molecular weights or viscosities, and optionally a surfactant.
