Title (EN) ISOCYANATE FUNCTIONAL ADHESIVE WIHICH BONDS PRIMERLESS TO SILANATED ACRYLIC POLYOL BASED COATING
(FR) ADHÉSIF À FONCTION ISOCYANATE SE LIANT SANS COUCHE D'APPRÊT À UN REVÊTEMENT À BASE DE POLYOL ACRYLIQUE SILANÉ
Abstract:
(EN) Disclosed is a composition including one or more isocyanate functional prepolymers; one or more catalysts for the reaction of isocyanate moieties and active hydrogen containing moieties; one or more mercapto silanes; one or more amino silanes, isocyanato silanes or a mixture thereof; one or more reinforcing fillers comprising one or more high surface area carbon blacks; one or more untreated calcium carbonates; one or more polyisocyanates having an isocyanate functionality of about 2 or greater; and one or more linear plasticizers. Preferably, the isocyanate functional prepolymer is prepared in the presence of at least a portion of the linear plasticizer. Preferably, the isocyanate functional polymer is prepared in the presence of a dialkyl malonate. The composition may be one-part adhesive composition. Also disclosed are methods of applying the compositions to substrates. The composition bonds primerlessly to hard to bond to coatings, such as coatings prepared from compositions including a silanated component, such as a silanated acrylopolyols, or having silica clusters.
(FR) L'invention concerne une composition comportant un ou plusieurs prépolymères à fonction isocyanate ; un ou plusieurs catalyseurs destinés à la réaction de fractions isocyanate et de fractions contenant de l'hydrogène actif ; un ou plusieurs silanes mercapto ; un ou plusieurs aminosilanes, isocyanato-silanes ou un mélange de ces derniers ; une ou plusieurs charges renforçantes comprenant un ou plusieurs noirs de carbone à surface élevée ; un ou plusieurs carbonates de calcium non traités ; un ou plusieurs polyisocyanates possédant une fonctionnalité isocyanate d'environ 2 ou plus ; et un ou plusieurs plastifiants linéaires. De préférence, le prépolymère à fonction isocyanate est préparé en présence d'au moins une partie du plastifiant linéaire. De préférence, le polymère à fonction isocyanate est préparé en présence d'un malonate de dialkyle. La composition peut être une composition adhésive en une partie. L'invention concerne également des procédés d’application des compositions aux substrats. La composition se lie sans couche d'apprêt à des revêtements difficiles à lier, tels que des revêtements préparés à partir de compositions comportant un constituant silané, tel qu'un acrylopolyol silané, ou possédant des agrégats de silice.
