20080221546 | NOVEL DISPOSABLE DIAPER CONSTRUCTION AND ADHESIVE - A novel spray-on adhesive composition is made from a high melt index polymer and a rosin ester tackifier that interact to produce a composition that can form a low VOC, non-tacky, hot melt adhesive material that can be used in disposable article manufacture. The adhesive provides surprisingly high initial adhesion. Additionally, the adhesive is thermally stable at hot melt application conditions, low in cost, easily applied, and produces high quality disposable articles. | 09-11-2008 |
20100047499 | Hot Melt Adhesive Compositions Comprising Metathesized Unsaturated Polyol Ester Wax - Disclosed are hot melt adhesive compositions comprising a metathesized unsaturated polyol ester wax. Typically, the metathesized unsaturated polyol ester wax is derived from renewable starting materials such as vegetable oils or animal fats. The metathesized unsaturated polyol ester wax typically replaces a portion or all of a petroleum-derived wax or synthetic wax in various hot melt adhesive compositions. The hot melt adhesives may be conventional hot melt adhesives or hot melt pressure-sensitive adhesives. | 02-25-2010 |
20100167074 | ADHESIVE FOR DIFFICULT TO ADHERE POLYMER COATED BOARD STOCK - Adhesives are uniquely formulated to ensure appropriate adhesion to polymer coated paperboard. Such adhesives can be used in case and carton sealing applications and other applications using the coated paperboard stock material. The coatings can often pose problems for adhesives designed to adhere to the coated surfaces. The adhesives of the invention form adequate adhesive bonds to the coated corrugated paperboard such that the paperboard can be adhered to other substrates or to itself in case and carton sealing purposes. Coated paper board or coated corrugated board stock is commonly used in packaging materials where the package is exposed to extremes of temperature, humidity or liquid moisture. The coatings are used in packaging materials to withstand sufficient amounts of moisture such that the strength of either the adhesive used in the manufacture of the paperboard or the cellulosic base material of the paperboard are not compromised. The coatings on the paperboard or corrugated board stock impede penetration of moisture into the paperboard materials. | 07-01-2010 |
20120213956 | FUGITIVE ADHESIVE AND METHOD - Described herein are fugitive hot melt adhesive compositions having a substantial weight percent of renewable plant-based content. The adhesive compositions impart high initial adhesive bond strength between an object and a substrate quickly after application in the molten state, wherein the adhesive bond strength is spontaneously substantially reduced to a very low or near zero level after a short time, for example between about 1 minute and 60 minutes after application. Methods of use and articles formed using the compositions are also described. | 08-23-2012 |
