Abstract
Improved coating and method of forming a nondewettable coating in a reactive carbon monoxide atmosphere wherein a small portion of palladium, platinum or mixture thereof is added to the coating mixture before the mixture is applied to the substrate. Alternatively, in the case of electrolytic deposition, a thin layer of palladium, platinum or mixture thereof is, e.g. electrolessly or by sputtering or silkscreening, deposited on a substrate before a tin or tin alloy coating is deposited, such as by sputtering, silkscreening, etc. The reaction temperature required to form a nondewettable bond is reduced or increased depending on the tin alloy content, but it appears that if platinum or palladium is participating in the reaction for the same alloy, the temperature for achieving the bond appears to be reduced.
