ABSTRACT:
A process for preparing an antirust composition is described, particularly for underbody and already painted and finished motor vehicle parts, having improved physical and mechanical properties, which comprises: (1) preparing a reaction mixture obtained by mixing a preformed product containing an emulsifier, an organic diluent and an inorganic carbonate, with one or more monomers, water and a radicalic catalyst, (2) heating the mixture thus obtained to polymerize the monomer, and (3) further heating to vaporize water, optionally under vacuum, the polymer being formed in situ in the basic gelified composition. A method to provide better rust strength to painted parts or surfaces using the composition thus prepared is also described.
