Abstract (en)
[origin: EP2330140A1] Use of aldimine compounds (I) as a cleaning agent or as part of a cleaning agent composition for reactive polyurethane compositions, preferably for reactive polyurethane hot melt adhesives, is claimed. Use of aldimine compounds of formula ([Y1-C(R2)(R1)-CH=N] n-E-XH) (I) as a cleaning agent or as part of a cleaning agent composition for reactive polyurethane compositions, preferably for reactive polyurethane hot melt adhesives, is claimed. Either R1, R2 : monovalent 1-12C-hydrocarbyl; or R1R2 : bivalent 4-12C-hydrocarbyl, which is part of an optionally substituted 5-8C (preferably 6C) carbocyclic ring; Y1 : monovalent 1-32C-hydrocarbyl, which is optionally contains at least one heteroatom, preferably O in the form of ether-, carbonyl- or ester-groups; E : (n+1)-valent 2-12C-hydrocarbyl, which optionally contains at least one heteroatom, preferably in from of ether-oxygen or tert-amine nitrogen; X : O, S or N-R8; R8 : 1-20C-monovalent 1-20C-hydrocarbyl, which optionally contains at least one carboxylic acid ester-, nitrile-, nitro-, phosphonic acid ester-, sulfone- or sulfonic acid ester-group, or -E[N=CH-C(R1)(R2)-Y1] n; and n : 1-3. Independent claims are included for: (1) a cleaning agent composition for reactive polyurethane compositions, preferably for reactive polyurethane hot melt adhesives comprising (I), and at least one carrier-A, which contains no isocyanate reactive functional groups; and (2) a method for cleaning a manufacturing- or an application system or device of reactive polyurethane composition comprising adding (I) or the cleaning composition into the reactive polyurethane composition present in the system or device and displacing from the system or device.
