Abstract
This invention provides a one-part, room temperature moisture curable resin composition which comprises a ketimine prepared by reacting a ketone having a substituent at .alpha. position and a polyamine having at least two amino groups within its molecule wherein .alpha. position is methylene, and a main polymer which is an epoxy resin and/or a modified silicone having at least two hydrolyzable alkoxysilyl groups in its molecule, and which exhibits good shelf stability and high curing rate once taken out of the container, and which may further exhibit flexibility; a one-part, room temperature moisture curable resin composition which exhibits good shelf stability and curability as well as wet surface adhesion or initial thixotropic properties; a silicon containing compound having ketimine group whose reaction with the epoxy resin during the storage is prevented by the presence of a bulky alkyl group near the ketimine group and which exhibits good shelf stability and curability, and its production method; a one-part, room temperature moisture curable resin composition containing said silicon containing compound adapted as a latent curing agent which exhibits good shelf stability and short curing period once taken out of the container; and a novel method of ketimine synthesis.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
