Patent number: 6046295Abstract: This invention provides aqueous dispersions of externally chain extended polyurethane compositions terminated by hydrolyzable and/or hydrolyzed silyl groups and containing anionic solubilizing or emulsifying groups, particularly carboxyl groups. The invention also provides methods of making both anionically and cationically stabilized polyurethane dispersions. This invention further provides polyurethane dispersions which are substantially organic solvent free, (e.g. less than about 7 weight percent organic solvent) which cure to water and solvent resistant, tough, scratch resistant, preferably light stable (non-yellowing) polyurethane films. Such films are particularly useful as coatings for wood substrates, including wood floorings, furniture, and marine surfaces.Type: GrantFiled: August 30, 1996Date of Patent: April 4, 2000Assignee: 3M Innovative Properties CompanyInventors: Kurt C.

Patent number: 5587502Abstract: The present invention provides a moisture-curable alkoxysilane functional polyurethane prepared from a hydroxy functional alkoxysilane. The hydroxy functional alkoxysilane is a hydroxyalkylenecarbamoylalkylene-alkoxysilanes referred to as a "hydroxycarbamoylsilane". The alkoxysilane functional polyurethanes may be used in a variety of applications to provide, for example, moisture-curable adhesives, sealants, putties and the like.Type: GrantFiled: June 2, 1995Date of Patent: December 24, 1996Assignee: Minnesota Mining & Manufacturing CompanyInventors: Dean M.

Patent number: 5558277Abstract: A pneumatic applicator for shear thinning viscous coating materials that includes a nozzle having a through material opening, and a distal end surface at an outlet end of the nozzle, an air operated system for dispensing viscous material at a steady rate through the nozzle, and an air directing housing defining, with the outer surface of the nozzle, an air chamber around the nozzle. The air directing housing includes a front end having a distal surface and defines an air outlet opening for the air chamber from an inner surface to the distal surface of the air directing housing.Type: GrantFiled: October 30, 1995Date of Patent: September 24, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Ian R.

Patent number: 5536531Abstract: A pneumatic applicator for shear thinning viscous coating materials that includes a nozzle, an air operated system for dispensing viscous material at a steady rate through the nozzle, and an air directing housing defining an air chamber around the nozzle. The air directing housing defines an air outlet opening for the air chamber around the nozzle. Distal surfaces of the housing and nozzle are close to co-planar and the air outlet opening has an area in the range of about 5 to 15 square millimeters. An adjustable system directs air under pressure into the air chamber so that when the viscous material is dispensed through the nozzle at a generally uniform rate, air can be directed into the chamber and out through the air outlet opening around the nozzle and only the amount of air being directed into the chamber need be adjusted to cause viscous material being dispensed from the nozzle to be applied to a surface adjacent the nozzle in coatings of various widths and thicknesses.Type: GrantFiled: July 26, 1994Date of Patent: July 16, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Ian R. Owen, Alan G. McKown
