The present invention is directed to a curable and debondable two-part (2K) hybrid adhesive composition comprising: i) a first part comprising: a) epoxy resin; b) (meth)acrylate monomer; c) an electrolyte; d) a solubilizer; and e) a filler; and, ii) a second part comprising: a) a curing agent consisting of at least one compound possessing at least two epoxide reactive groups per molecule; b) an accelerator; and, c) a filler.

Two component (2K) curable adhesive composition

The present invention is directed to a curable and debondable two-part (2K) adhesive composition comprising: i) a first part comprising: a) epoxy resin; b) an electrolyte; c) optionally, a solubilizer; and, ii) a second part comprising: a) a curing agent consisting of at least one compound possessing at least two epoxide reactive groups per molecule; and, b) an accelerator; wherein said composition further comprises an electrically non-conductive filler and, optionally a toughener.

The present invention is directed to a curable and one component (1K) debondable adhesive composition comprising: a) epoxy resin; b) a curing agent for said epoxy resin; c) an electrolyte; and, d) an electrically non-conductive filler; wherein said composition comprises at least one of: e) a combination of a solubilizer and a toughener; and, f) electrically conductive particles.

One component (1K) curable adhesive composition

The present invention relates to an aqueous dispersion, comprising or consisting of A) at least one cyclic olefin copolymer, B) at least one surfactant; optionally C) at least one adhesion promoter; optionally D) at least one film-forming resin; optionally E) at least one additive; and F) water. Additionally, the invention relates to methods of manufacturing the aqueous dispersion, to an article, which comprises at least one substrate and at least one coating layer obtained from the aqueous dispersion and applied onto the substrate; and to methods of improving MVTR of a substrate.

Water based dispersion to make coatings with increased MVTR barrier properties

The invention relates to use of an adhesion promoting organic compound comprising at least one tertiary amine group, bonded via a bridge-constituting divalent radical, with the carbonyl carbon atom of an amide group, wherein the bridge-constituting divalent radical comprises two carbon atoms as bridge atoms, for anticorrosion pretreatment of metallic materials before painting and to aqueous compositions containing the adhesion promoting organic compound which generate conversion layers based on the elements Zr, Ti and/or Si. The present invention further comprises a process for anticorrosion coating of components at least partly manufactured from metallic materials comprising a pretreatment using acidic aqueous compositions according to the invention and subsequent painting. In a further aspect, the invention relates to a metallic substrate having a mixed organic/inorganic coating consisting of oxides, hydroxides and/or oxyfluorides of the elements Zr, Ti and/or Si and of the adhesion promoting organic compounds.

Use of an adhesion promoter obtainable as a reaction product of a di- or poly amine with &#x3b1;,&#x3b2;-unsaturated carboxylic acid derivatives for metal surface treatment

The present invention relates to a method for reversibly bonding a first and a second substrate, wherein at least the first substrate is an electrically non-conductive substrate, the method comprising: coating the surface of the electrically non-conductive substrate(s) with a conductive ink; applying an electrically debondable hot melt adhesive composition to the conductive ink-coated surface of the first substrate and/or the second substrate; contacting the first and the second substrates such that the electrically debondable hot melt adhesive composition is interposed between the two substrates; allowing formation of an adhesive bond between the two substrates to provide bonded substrates; and optionally applying a voltage to the bonded substrates whereby adhesion at least one interface between the electrically debondable hot melt adhesive composition and a substrate surface is substantially weakened. Furthermore, the present invention relates to the bonded substrates thus obtained.

Electrical debonding of PU hot melt adhesives by use of conductive inks

The present invention relates to hydrophilic coatings for heat exchangers, and methods and compositions for depositing such coatings comprising applying a composition comprising at least one curable polyvinyl alcohol and at least one wetting agent to a surface of a metal substrate and curing the composition on the surface of the metal substrate.

Hydrophilic coating for heat exchangers

The present invention relates to a water-based can inner coating based on a copolymer or a copolymer blend of at least one aliphatic and acyclic alkene having at least one &#x3b1;,&#x3b2;-unsaturated carboxylic acid in water-dispersed form, wherein the can inner coating contains a water-soluble curing agent selected from inorganic compounds of the elements Zr and/or Ti, so that the need for using organic hardener systems can be largely avoided. The present invention further relates to a method for the internal coating of tin cans or aluminum cans, in which the previously mentioned can inner coating is directly applied to the metallic inner surfaces of the cans and cured without any need to carry out a conversion treatment for improving coating adhesion of the inner surfaces of the cans.

Highly curable coating formulation for the inner surfaces of cans

The present invention relates to a method for manufacturing coated can lids from aluminum strip, and is based on the finding that flexible, easily formable coatings having high abrasion resistance result from the use of water-based lacquers containing a copolymer or a copolymer mixture of at least one aliphatic, acyclic alkene with at least one &#x3b1;,&#x3b2;-unsaturated carboxylic acid in water-dispersed form, and a curing system. In a preferred embodiment of the method, the application of a primer coating can be dispensed with entirely when water-soluble compounds of the elements Zr and/or Ti in the lacquer are used as the curing system.
