Title (EN) CURABLE COMPOSITION INCLUDING EPOXY RESIN AND CURABLE SOLID FILLER
(FR) COMPOSITION DURCISSABLE COMPRENANT UNE RÉSINE ÉPOXY ET UNE CHARGE SOLIDE DURCISSABLE
Abstract:
(EN) The present disclosure provides a curable composition. The curable composition includes a liquid epoxy resin component, a curative component, and a curable resin filler component. At least a portion of curable resin filler is dispersed in the liquid epoxy resin and solid at about 25 °C. According to various examples, the curable composition can produce a film having good tackiness and improved handling characteristics. Additionally, according to some examples, a cured product of the curable composition can have a Wet Glass Transition Temperature and a Dry Glass Transition Temperature that are substantially the same.
(FR) La présente invention concerne une composition durcissable. La composition durcissable comprend un composant de résine époxy liquide, un composant durcisseur et un composant de charge de résine durcissable. Au moins une partie de la charge de résine durcissable est dispersée dans la résine époxy liquide et solide à environ 25 °C. Selon divers exemples, la composition durcissable peut produire un film ayant une bonne adhésivité et des caractéristiques de manipulation améliorées. De plus, selon certains exemples, un produit durci de la composition durcissable peut avoir une température de transition vitreuse humide et une température de transition vitreuse sèche qui sont sensiblement les mêmes.
