Abstract
(EN)
Advanced resins and unadvanced epoxy resins are disclosed wherein the unadvanced compound and at least a portion of the advanced epoxy resin contains at least one -O-R1-O- or -(O-CH2-CHR2)n-O- group as a bridge between two groups selected independently from the group consisting of (1) a saturated or unsaturated cycloaliphatic group, (2) an aromatic group, (3) a group represented by formula (I), or (4) a group represented by formula (II). Also disclosed are nucleophilic derivatives thereof, as well as curable compositions and coating compositions containing the advanced or unadvanced epoxy resins or nucleophilic modified advanced or unadvanced epoxy resins. These advanced resins and unadvanced epoxy resins provide coatings with good flexibility or formability as exhibited by good flexural or formable properties determined by reverse impact, T-bend and wedge-bend tests, chip resistance, and with good corrosion resistance and throwpower.

(FR)
Résines traditionnelles et résines époxy non traditionnelles dans lesquelles le composé non traditionnel et au moins une partie de la résine époxy traditionnelle contiennent au moins un groupe -O-R1-O- ou (O-CH2-CHR2)n-O- utilisé comme pont entre deux groupes choisis indépendamment dans le groupe composé de (1) un groupe cycloaliphatique saturé ou insaturé, (2) un groupe aromatique, (3) un groupe représenté par la formule (I), ou (4) un groupe représenté par la formule (II). L'invention concerne également leurs dérivés nucléophiles ainsi que des compositions polymérisables et des compositions de revêtement contenant les résines traditionnelles ou les résines époxy non traditionnelles ou des résines traditionnelles ou époxy non traditionnelles modifiées nucléophiles. Ces résines traditionnelles et ces résines époxy non traditionnelles permettent d'obtenir des revêtements présentant une bonne flexibilité ou une bonne aptitude au formage démontrées par de bonnes propriétés de flexion ou de formage déterminées par des essais de détachement brusque, de flexion T et de flexion en coin, une résistance à l'écaillage ainsi qu'une bonne résistance à la corrosion et un bon pouvoir de pénétration.
