Parylene stabilization
First Claim
1. An article comprising:
- (a) a solid substrate; and
(b) a coating on said substrate, said coating comprising parylene admixed with (i) a sterically hindered phenol vaporizable at a temperature in the range of about 20°
C. to about 150°
C. (ii) pyrogallol wherein the amount of phenol or pyrogallol admixed with the parylene is about 0.1 to about 15 percent by weight based on the weight of the parylene.

Abstract
A process for making an article comprising (a) a solid substrate and (b) a coating on said substrate, said coating comprising parylene admixed with (i) a sterically hindered phenol vaporizable at a temperature in the range of about 20° C. to about 150° C. or (ii) pyrogallol,
Said process comprising the following steps:
(A) vaporizing a substituted or unsubstituted p-xylylene diradical and said phenol or pyrogallol; and
(B) introducing the vapors from step (A) into a deposition zone containing the substrate, said zone being under vacuum and at a temperature at which the vapors will condense,
Whereby the vapors condense on the substrate, the diradical polymerizing to parylene, coating the substrate and forming the article, and the defined article.
