The adhesive is of a contact type, which permits adherends to be easily fastened without being temporarily pressed and is, applicable to any type of adherends contrary to aqueous adhesives, and is cured under room temperature in a relatively short period of time even if the adherends are not of a moisture-permeating type.

Why it's free to use
- Filed February 11, 1991 and granted June 4, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 11, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 11, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
