Open the CIPO recordAbstract From the Canadian patent
The inability of organosiloxane compositions containing an organohydrogensiloxane as the curing agent and a platinum group metal-containing catalyst to cure completely on substrates containing residues of solder fluxes or other cure-inhibiting materials is remedied by coating at least that portion of the substrate containing the residue with a layer of an organosilicon compound containing at least two silicon-bonded hydrogen atoms per molecule prior to application of the curable organosiloxane composition.

Why it's free to use
- Filed July 4, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 4, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 4, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
