The invention is directed toward a hot melt adhesive composition and processes for producing the same. The hot melt adhesive composition comprises: at least one non-thermoplastic hydrocarbon elastomer; at least one thermoplastic additive, wherein a ratio of melt viscosity of the at least one thermoplastic additive to melt viscosity of the at least one non-thermoplastic hydrocarbon elastomer is less than about 1:20 when measured at a shear rate of 100 seconds at a particular hot melt processing temperature; and at least one modifier.

A method for maintaining a plurality of wood veneer substrates in fixed relation to each other that includes positioning a plurality of wood veneer substrates in relation to each other, and applying a tape to the substrates to maintain the substrates in fixed relation to each other. The tape is capable of maintaining wood veneer substrates in fixed relation to each other before and during a lamination process in which the substrates are laminated to an underlying base, and is cleanly removable from the substrates following the lamination process.

A linerless, coreless roll of tape includes a backing layer having an adhesive layer formed on one side. The tape is formed into a roll having a plurality of wraps with the adhesive side facing outwardly. The tape is sufficiently stiff and self-supporting to obviate the need for support material, and the entire roll, including the last wrap, is completely usable for its intended purpose without wasting any tape. As lint removal tape, the tape is used while it is still on the roll, and the tape is removed from the roll only after use, to discard it. The roll can be sufficiently compressible to create a plane of contact during use to remove lint. The roll of tape can be mounted on an applicator.

A masking tape is provided that is suitable for insertion under many moldings and gaskets which not only masks the molding or gasket but also facilitates refinishing under at least a portion of the molding or gasket. The masking tape is constructed to include a longitudinal non-adhesive portion and a longitudinal adhesive portion, wherein the non-adhesive portion is stiffer than the adhesive portion and is sufficiently stiff to facilitate easy insertion of the non-adhesive portion beneath at least a portion of the molding or gasket to be masked while the adhesive portion is sufficiently flexible to permit the wrapping thereof around the molding or gasket. The stiffened portion advantageously provides a dual purpose of facilitating the easy insertion of the non-adhesive portion beneath the molding or gasket and creating a lever action during application between the molding or gasket and the wall or panel to which the molding or gasket is mounted. This lever action creates a force which tends to separate or lift an edge of the molding or gasket from the wall or panel to open the wall or panel under the molding or gasket for refinishing. The masking tape is especially applicable for masking flexible gaskets that include a leg portion that overlies an adjacent panel that is to be refinished.
