A powder coating composition comprises a mixture of first and second component powder coating compositions which are separated preferably widely separated, in a triboelectric reference series indicative of the extent to which powder coating compositions may be distinguishable from one another when electrically charged. The mixed powder coating composition is especially suitable for coating articles having recessed portions. A quantitative basis is given for determining the separation of the individual component compositions in the triboelectric reference series, and preferred minimum separation criteria are given.

Why it's free to use
- Filed February 8, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 8, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 8, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
