Abstract
(A1) Die vorliegende Erfindung betrifft Klebstoff-Zusammensetzungen fuer loesbare Klebeverbindungen auf der Basis von Klebstoffmatrizes und Expansionsstoffen, wobei die Partikel des Expansionsstoffes mindestens teilweise verkapselt sind. Die Erfindung bezieht sich weiterhin auf deren Verwendung in loesbaren Klebeverbindungen und Verfahren zum Verbinden bzw. Loesen von Klebeverbindungen in Luftfahrzeugen.
DE 102009019483 A1 UPAB: 20101122 NOVELTY - Adhesive composition (I) comprises an adhesive matrix and a particulate expansion material, where the particles of the expansion material is at least partially encapsulated and/or coated. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method of bonding components, comprising applying (I) on at least a surface of at least a component, contacting the adhesive-bearing surfaces of the component with at least one another component and hardening (I) to form an adhesive bond comprising an adhesive layer and at least two components; (2) a method for detaching bonded components, comprising heating the adhesive bond to at least an expansion temperature of the encapsulated expansion material and separating the bonded components; and (3) a composite made of at least two components and an adhesive layer comprising (I). USE - (I) is useful: for bonding and detaching components such as metal, plastic, wood, glass, natural or synthetic material and composite; for making a composite; and in aircraft construction, vehicle construction and shipbuilding (all claimed). ADVANTAGE - (I): has sufficient bond strength during the application period, equivalent mechanical strength as conventional adhesive compositions, sufficient chemical and thermal resistance and improved shelf life; can be detached easily without damaging or destroying the bonded components; is easy to apply; and provides an adhesive bond with improved aging characteristics, hence permits a long period of use.
