Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
An electronic component having a coating of an ultraviolet light curable composition directly against said component, said coating consisting essentially of a completely ultraviolet light cured product obtained from a mixture of 51 to 59% of a bisphenol A epoxy diacrylate, 34.8 to 44.4% of a cycloaliphatic methacrylate, about 2% of a photoinitiator, about 2% of a peroxide, about 0.2% of a wetting agent, and about 2% of a wet adhesion monomer.
Claim 2
Dependent Claim
72 words
An electronic component having a coating of an ultraviolet light curable composition directly against said component, said coating consisting essentially of a completely ultraviolet light cured product obtained from a mixture of 51 to 59% of a bisphenol A epoxy diacrylate, 34.8 to 44.4% of a cycloaliphatic methacrylate, about 2% of a photoinitiator, about 2% of a peroxide, about 0.2% of a wetting agent, and about 2% of a wet adhesion monomer.
Claim 3
Dependent Claim
12 words
A component according to claim 1 wherein said methacrylate is cyclohexyl methacrylate.
Claim 4
Dependent Claim
14 words
A component according to claim 1 wherein said component is a metallized film capacitor.
Claim 5
Dependent Claim
15 words
A component according to claim 3 wherein said component is a multilayer metallized film capacitor.
Claim 6
Dependent Claim
