The present invention is directed to methods of making natural or synthetic latex articles without the use of accelerators, thiurams or carbamates. The sine wave filter is designed to have a resonant frequency higher than the maximum operational frequency of the drive, and a Q such that, at the maximum operational frequency of the drive, the filter provides a voltage gain equal to the ratio of the desired voltage to the drive’s maximum output power at the maximum operational frequency. Then, the titanium layer is formed on the substrate by combining a second precursor with the seed layer by CVD.
