  • Siloxane organic hybrid materials providing flexibility to epoxy-based coating compositions
    Patent number: 9273225
    Abstract: Disclosed herein are epoxy-based compositions that include a polysiloxane flexibilizer and amino-functional alkoxysilane, which provides flexibility, hardness and gloss to such compositions and that are useful as coatings, adhesives, sealants and composites. Also disclosed are cured compositions and substrates coated with such epoxy-based compositions.
    Type: Grant
    Filed: September 12, 2012
    Date of Patent: March 1, 2016
