Title (EN) CURABLE COATING COMPOSITION AND EPOXY RESIN ADDUCT USEFUL THEREIN
(FR) COMPOSITION DE REVETEMENT POLYMERISABLE ET PRODUIT D'ADDITION A BASE DE RESINE EPOXYDE UTILE DANS CETTE COMPOSITION
Abstract:
(EN) A curable coating composition is prepared from two components; (1) a component having more than one epoxide group (an epoxy resin) and (2) a component having more than one group reactive with the epoxy groups of components (1) (i.e., a polyhydric phenol). Either component (1) or (2) is the reaction product of a compound containing at least one primary or secondary amino group and at least one aliphatic hydroxyl group with an epoxy resin and optionally a component reactive therewith. This reaction product contains terminal aliphatic hydroxyl groups and epoxy groups or groups reactive with epoxy groups. The components (1) and (2) are preferably normally solid materials and the coating composition is a powder coating composition. The coatings prepared from these powder coating compositions which contain the adduct having both aliphatic -OH and epoxy or phenolic -OH groups exhibit significantly improved adhesion when applied to a metal substrate, including an untreated mild steel substrate, then a conventional epoxy resin, powder coating composition.
(FR) Composition de revêtement polymérisable préparée à partir de deux composants: (1) un composant possédant plus d'un groupe époxyde (une résine époxyde) et (2) un composant possédant plus d'un groupe réagissant avec les groupes époxyde du composant (1) (c'est-à-dire un phénol polyhydrique). Chaque composant (1) et (2) est le produit de réaction d'un composé contenant au moins un groupe amino primaire ou secondaire et au moins un groupe hydroxyle aliphatique avec une résine époxyde et éventuellement un composant réagissant avec la résine. Ce produit de réaction contient des groupes terminaux hydroxyles aliphatiques et des groupes époxydes ou des groupes réagissant avec les groupes époxydes. Les composants (1) et (2) sont de préférence des matériaux normalement solides et la composition de revêtement est une composition de revêtement en poudre. Les revêtements préparés à partir de ces compositions de revêtement en poudre contenant le produit d'addition possédant aussi bien des groupes -OH aliphatiques que des groupes -OH époxydes ou phénoliques présentent une adhésion sensiblement améliorée lorsqu'ils sont appliqués sur un substrat métallique, y compris un substrat en acier doux non traité, par rapport à une composition de revêtement conventionnelle en poudre à base de résines époxydes.
