Title (DE) WARMHÄRTENDE LÖSUNGSMITTELFREIE EINKOMPONENTEN-MASSEN UND IHRE VERWENDUNG
(EN) THERMOSETTING SOLVENT-FREE SINGLE-COMPONENT SUBSTANCES AND USE THEREOF
(FR) MASSES A UN SEUL CONSTITUANT DURCISSANT A CHAUD ET EXEMPTES DE SOLVANT ET UTILISATION DESDITES MASSES
Abstract:
(DE) Vorgeschlagen wird eine warmhärtende, lösungsmittelfreie Einkomponenten-Masse mit einer Lagerstabilität bei Raumtemperatur von mindestens 2 Wochen, bestehend aus (A) 5 - 90 Masseteilen einer mindestens difunktionellen (Iso)cyanat- Komponente, (B) 5 - 50 Masseteilen eines latenten, bis zu einer Temperatur von mindestens 40°C festen Härters auf Basis von Stickstoffverbindungen, die zur Additionsvernetzung geeignet sind, (C) 0 - 50 Masseteilen einer epoxidhaltigen Verbindung, D) 0 - 50 Masseteilen von Modifikatoren, wobei die Summe aller Masseteile 100 betragt, sowie ihre Verwendung für das Verkleben, Vergiessen, Abdichten und Beschichten von Substraten, insbesondere von elektronischen Bauteilen Die Masse härtet bei 120-150°C innerhalb von Sekunden aus
(EN) Disclosed is a thermosetting, solvent-free single-component substance that has a minimum shelf life of 2 weeks at ambient temperature and is composed of (A) 5 to 90 parts by weight of an at least bifunctional (iso)cyanate component, (B) 5 to 50 parts by weight of a latent hardener which is solid up to a temperature of at least 40 °C and is based on nitrogen compounds suitable for addition-crosslinking, (C) 0 to 50 parts by weight of an epoxy-containing compound, D) 0 to 50 parts by weight of modifiers, the sum of all parts by weight amounting to 100. Also disclosed is the use of said substance for gluing, pouring, sealing, and coating substrates, particularly of electronic components. The inventive substance is cured within seconds at 120 to 150 °C.
(FR) Masse à un seul constituant durcissant à chaud et exemptes de solvant, ayant une durée de conservation à température ambiante d'au moins 2 semaines. Ladite masse est constituée (A) de 5 à 90 parties en masse d'un constituant (iso)cyanate au moins bifonctionnel, (B) de 5 à 50 parties en masse d'un durcissant latent solide jusqu'à une température d'au moins 40 °C, à base de composés azotés adaptés pour la réticulation par réaction d'addition, (C) 0 à 50 parties en masse d'une liaison contenant de l'époxyde et (D) 0 à 50 parties en masse de modificateurs, la somme de toutes les parties en masse étant de 100. La présente invention concerne en outre l'utilisation de ladite masse pour coller, encapsuler, étanchéifier et couvrir des substrats, en particulier de composants électroniques. Ladite masse durcit à 120-150 °C en quelques secondes.
