Abstract
A pressurized paint product that includes an magnetic aerosol paint composition disposed in a container. The magnetic aerosol paint composition includes volatile organic solvents, an alkyd resin, and ferromagnetic particles.
Claims27
An aerosol paint product comprising:
- (a) a container comprising a can, a valve cup with a valve assembly, a dip tube and an actuator;
- and
- (b) a magnetic aerosol paint composition disposed within said container, said magnetic aerosol paint composition comprising:
- (i) at least one volatile organic solvent;
- (ii) at least one film-forming resin;
- (iii) ferromagnetic particles;
- and
- (iv) a propellant selected from the group consisting of ethers, C1–C4 saturated hydrocarbons, hydrofluorocarbons, and mixtures of the foregoing;
- wherein the ferromagnetic particles are present at a level of at least 25% of the total weight of ferromagnetic particles, resin and organic solvent.

A process of imparting magnetic properties to the surface of a substrate which process comprises:
- (1) providing an aerosol paint product comprising:
- (a) a container comprising a can, a valve cup with a valve assembly, a dip tube and an actuator;
- and
- (b) a magnetic aerosol paint composition disposed within said container, said magnetic aerosol paint composition comprising:
