| 20100040777 | SOLID TYPE RUBBER-BASED PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEET THEREOF - The present invention relates to a solid type rubber-based pressure-sensitive adhesive composition, which is prepared by adding a tackifier, a softener, and an isocyanate-based crosslinking agent reactable with active hydrogen into an acrylic rubber containing a monomer having an active hydrogen-containing functional group as a copolymerization component to thereby obtain a solventless and nonaqueous pressure-sensitive adhesive composition, and particularly it relates to a solid type rubber-based pressure-sensitive adhesive composition having the above-mentioned constitution, in which the above-mentioned acrylic rubber includes a copolymer containing butyl acrylate as a main component, and as the copolymerization component a monomer having a hydroxyl group or a carboxyl group as the active hydrogen-containing functional group. | 02-18-2010 |
| 20100189894 | Packaging container with a laminate and process for manufacturing the laminate - A packaging container is such that a laminate features a film-shaped substrate bonded to a hot-sealing layer via a contact adhesive layer for easy opening and reclosing the container—arranged between an adhesive layer of permanent adhesive and a hot-sealing layer and is bonded to itself via a sealing seam or to another film to form a pouch or, as lid, bonded to the edge of a pouch. For the production of the laminate, the film-type substrate is coated—via liquid-film coating using the curtain coating or slide-coating method—with a multi-layer liquid film comprising at least an adhesive layer, the contact adhesive layer and the cohesively rupturing hot-sealing layer. | 07-29-2010 |
| 20110223328 | TRAILER FLOORING WITH HOTMELT COATING - A method for providing improved moisture protection to a wood board flooring comprising a plurality of solid wood components which together form the wood board, such that the wood board has a first surface and a second surface, the method comprising: applying a coating to at least one of the first and second surfaces of the wood board, the coating being substantially free of water and solvents. | 09-15-2011 |
| 20110300295 | JETTING DISPENSER AND METHOD OF JETTING HIGHLY COHESIVE ADHESIVES - Jetting dispensers and methods of non-contact dispensing a hot melt adhesive onto a substrate. The method may include jetting a plurality of droplets of the hot melt adhesive from a nozzle outlet toward the substrate in a direction of travel. Each droplet has a droplet length approximately aligned with the direction of travel and a droplet width shorter than the droplet length. The jetting is controlled such that each of the droplets does not collapse into a spherical-shaped droplet during flight from the nozzle outlet to the substrate. The nozzle outlet may be heated to a first temperature, and the method may further include rapidly heating each droplet of the hot melt adhesive to a second temperature higher than the first temperature upon release from the nozzle outlet. | 12-08-2011 |
| 20120082784 | HOT-MELT EXTRUDED ADHESIVE TAPE - A molding method of hot-melt extruded adhesive tape includes a banded or foliated carrier with peelable surface. A feed mechanism is used to feed the carrier by a conveying mechanism. The thermoplastic rubber can be extruded by the extrusion feed mechanism onto the carrier's peelable surface through 0.2 mm˜1.0 mm extrusion port, so that at least a thin-profile and flat extruded adhesive is formed on the peelable surface. An intermittent controller enables the thermoplastic rubber to be arranged onto the carrier's peelable surface at interval or in continuously-extended pattern. A hardening mechanism is used to speed up the hardening of extruded adhesives into solid adhesive. The method can improve substantially the fabrication efficiency of the hot-melt extruded adhesive tapes, thus saving the material cost and improving the adhesion strength with better advantages and applicability. | 04-05-2012 |
| 20130202787 | LOW TEMPERATURE HOT MELT ADHESIVES FOR DISPOSABLE ARTICLES WITH HIGH CREEP RESISTANCE - The present invention is directed to adhesives suitable for application using a hot melt process at a relatively low temperature in the range of about 110° C. to about 130° C. Such adhesives exhibit desirable viscoelastic properties and are suitable for bonding an elastic attachment in the manufacture of disposable articles, such as disposable diapers. | 08-08-2013 |
| 20140065305 | METHOD OF APPLYING THERMOPLASTIC LIQUID ONTO A SUBSTRATE - Apparatus and methods for applying liquid onto a substrate include a nozzle configured to be connected to a liquid source. The nozzle further includes a distribution passage with a length that can receive the liquid. A piston is positioned in the distribution passage and a slit-shaped nozzle opening is in fluid communication with the distribution passage. The piston is movable in the distribution passage so as to vary the length that can receive the liquid. The nozzle opening communicates with the distribution passage via a plurality of spaced apart outlet channels having respective outlet ends. The outlet channels are formed between first and second nozzle pieces each having a tip portion at the outlet ends. At least one of the first or second nozzle pieces is flexible at the tip such that the outlet ends open when under positive fluid pressure and close when the fluid pressure is reduced. An application valve is coupled to the nozzle for selectively interrupting or enabling a flow of liquid to the distribution passage. | 03-06-2014 |
| 20140272131 | Hot Melt and Pressure Sensitive Adhesives that Include Highly-Plasticized Cellulose Esters and Methods and Articles Relating Thereto - Highly-plasticized cellulose esters may be useful as adhesives, including for use in producing laminates. For example, producing a laminate may include providing an adhesive melt that comprises an adhesive that comprises a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 75% by weight of the adhesive; applying the adhesive melt to a substrate; and allowing the adhesive melt to cool so as to yield a laminate on the substrate. | 09-18-2014 |
| 20140295076 | LOW SEAL INITIATION LID FOR RIGID SUBSTRATES - A polyolefin-based heat sealable and peelable lidding film. The peelable seal films comprise from 5 to 95 percent by weight of a polyolefin based plastomer or elastomer and from 5 to 95 percent by weight of a second plastomer or elastomer. The invention also relates to methods of making and using the heat sealable, peelable seal films, having improved low seal initiation temperature. | 10-02-2014 |
| 20150024132 | METHOD OF PRODUCING A SELF-ADHESIVE TAPE HAVING A LAYER OF PHOTOINITIATOR-FREE PRESSURE-SENSITIVE ACRYLATE HOTMELT ADHESIVE - The invention describes a double-sided, carrierless self-adhesive tape which can be used in particular for achieving very durable adhesive bonding of a variety of articles. This double-sided, carrierless self-adhesive tape is composed of a homogeneously crosslinked pressure-sensitive acrylate hotmelt composition of single-layer construction, which may have been lined with release materials such as siliconized release papers or release films. The double-sided, carrierless pressure-sensitive adhesive tape is characterized in that it is composed of a photoinitiator-free, thermally homogeneously crosslinked acrylate hotmelt which is crosslinked predominantly by way of urethane units. It is notable in particular for the fact that it is homogeneously chemically crosslinked through the layer and, in contrast to acrylate layers crosslinked by radiation (UV/EBC), does not exhibit any profile of crosslinking through the layer. It can be used in particular as an adhesive transfer tape for the permanent attachment of articles to a variety of substrates. | 01-22-2015 |
