Cc!, C&/and

A UV-c urable coating composirion comprising at least one photoinitiator selected from the group consisring of acylphosphine oxides, Michlcr‘s ketone. benzil, 2-chlorothioxanthone, and mixtures thereof; at least one photopolymerizable UV absorber having ethylenic unsaturation; at least one lJV-curable acrylic monomer; and silica; wherein the photoinitiator has the ability to absorb a significant portion of the total energy needed to cure the coating from wavelengths in which the UV absorber does not appreciably absorb.

Electrocoating

Composition

U.S. Patent 5,559,174. Sept. 24, 1996 PD. Clark et al, assignors to BASF Corp., C/i&n, N.J.

A coating composition comprising a principal resin comprising a self-addition epoxide resin-polyamine adduct with pendant alkylphenoxy groups; a crosslinker comprising a toluene diisocyanate com-

pound, a blocked isocyanurate of a hexane diisocyanate compound or mixtures thereof; a grind resin comprising the reaction product of an aromatic diglycidyl ether, an aromatic dial, an aminopolyalkoxy alcohol, a diamine and an alkylaryl glycidyl ether; a plasticizer; and pigments selected from a group consisting of inorganic. organometallic. and organic compounds.

Coating

A coating composition comprising a polyisocyanate component, and an isocyanate-reactive component comprising an aldimine/aspartate.

In-Situ Monitoring

N.Y

A method of in-situ monitoring of the change in thickness of a conductive film on an underlying body comprising inducing an eddy current in the film by producing an alternating electromagnetic field with a sensor proximate the film, the sensor including a coil, a capacitor electrically connected to the coil, and a ferrite pot core for shaping the electromagnetic field; and detecting a change in the current due to the change in thickness of the film.
