Open the CIPO recordAbstract From the Canadian patent
Organosiloxane compositions comprising specified combinations of MQ resins and liquid polyorganosiloxanes are applied as molten materials to form coatings that are non- flowable under ambient conditions and that can initially be remelted by heating the coating above its flow transition temperature. In the presence of moisture the flow transition temperature of the coating gradually increases due to the reaction of hydrolyzable groups on the polyorganosiloxane ingredient until the coating is converted to a non-flowable resin reinforced elastomer. Preferred coatings are non-transferable at 25°C. within ten minutes following application.

Why it's free to use
- Filed June 7, 1994 and granted April 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 7, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 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.
