| 20080206461 | Self Adhesive Material with a Water Soluble Protective Layer - The invention relates to self adhesive material (SAM) using water soluble film incorporated with surfactants and/or fillers as a protective layer, eliminating the release liner (backing liner). The water soluble film incorporated with surfactants and/or fillers, used as a protective liner, provides easy breakage, faster dissolution as well as easy application to an object. The invention also relates to a process for the preparation of self adhesive material (SAM) without release liner and an apparatus and a method for applying the self adhesive material (SAM) on an object. | 08-28-2008 |
| 20090053412 | Easy tear-off tape and method of making the same - A pressure-sensitive adhesive plastic tape can easily be manually torn, as from a supply roll, without the use of any tool. At least one lateral edge of the tape is beveled and inclined at an angle other than a right angle relative to the opposite major surfaces of the tape, thereby imparting a trapezoidal cross-section thereto. | 02-26-2009 |
| 20110200746 | METHOD FOR PRODUCING A PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET - It is provided a method for producing a pressure-sensitive adhesive tape or sheet which is superior in a heat-resistance. A mixture is prepared by uniformly mixing a specific polymer having hydrolyzable silyl end groups and urethane linkages and/or urea linkages in the main chains or side chains with tackifying resins. A fluorine-containing compound selected from the group consisting of boron trifluoride, complex of boron trifluoride, fluorinating agent and alkali metal salt of fluorine-containing inorganic acid is uniformly mixed into the mixture to obtain a precursor of a pressure-sensitive adhesive agent. The adhesive precursor is applied on the surface of a tape substrate or sheet substrate. It is obtained a pressure-sensitive adhesive layer having three-dimensional reticulation structures by curing the specific polymer having hydrolyzable silyl end groups. Thereby, it is obtained the pressure-sensitive adhesive tape or sheet. | 08-18-2011 |
