CURABLE SILICONE-(METH)ACRYLATE COMPOSITION AND METHODS FOR ITS PREPARATION AND USE
20230227700 · 2023-07-20 ·

A curable silicone-(meth)acrylate pressure sensitive composition is curable via hydrosilylation reaction to form a silicone-(meth)acrylate pressure sensitive adhesive with an initial adhesion. When the silicone-(meth)acrylate pressure sensitive adhesive is exposed to actinic radiation, the resulting silicone-(meth)acrylate adhesive has a subsequent adhesion, which is higher than the initial adhesion.

ASSEMBLY OF METAL PIPES WITH TWO-COMPONENT POLYURETHANE ADHESIVE

Described herein is a method for joining a first metal pipe with a second metal pipe, the pipes being joined together in an overlapping area by use of a two-component polyurethane adhesive that encapsulates the overlapping area, where the method includes the steps of:

(1) applying the two-component polyurethane adhesive onto an inner surface of a fixture;
(2) inserting one end of the first metal pipe into one end of the second metal pipe so as to form a pipe assembly having the overlapping area between the two ends, and putting the overlapping area of the pipe assembly into the fixture; (3) closing the fixture such that the overlapping area of the pipe assembly is fixed in the fixture, and such that the adhesive therein encapsulates the overlapping area of the pipe assembly; (4) curing the two-component polyurethane adhesive; and (5) optionally, removing the fixture from the pipe assembly.

Methods, processes, and apparatuses for producing dyed and welded substrates

A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

METHOD OF GLUING A WOOD PRODUCT AND A GLUED WOOD PRODUCT
20230219252 · 2023-07-13 · ·

The present invention relates to a method of producing a glued wood product for use in construction, comprising the steps of: providing at least two wooden pieces each piece comprising at least one joining face; creating a groove in at least one of said joining faces where the groove is arranged between a pair of peripheral edges; applying adhesive onto at least one of the joining faces of at least a first of said two wooden pieces; arranging said first wooden piece so that the joining face which comprises the applied adhesive meets a corresponding joining face of said second wooden piece, wherein at least one of said two joining faces comprises said groove; pressing the two joining faces towards each other so that the adhesive is compressed between said two wooden pieces, and maintaining said pressing for a sufficient time to bond the wooden pieces to each other; wherein the applied pressing force is strong enough to force the wood tissue to collapse at a contact area until the pressure force is transmitted primarily through the adhesive, wherein said contact area is defined by the surface area whereat the two joining faces of said wooden pieces contact each other upon being pressed together.
