The present invention discloses an adhesive composition comprising a protein component, an azetidinium functionalized polymer component and a viscosity modifying component. The preferred protein is a soy protein and the viscosity modifying component is preferably a sulfite reducing agent, a thiol, or combinations thereof. The invention provides for a high solids, lower viscosity adhesive formulation. The present invention also relates to a composite and a method of making a composite comprising a substrate and the adhesive composition of the present invention.
La présente invention porte sur une composition adhésive comprenant un composant protéique, un composant polymère à fonction azétidinium et un composant modifiant la viscosité. La protéine préférée est une protéine de soja et le composant modifiant la viscosité est, de préférence, un agent réducteur de sulfite, un thiol ou des combinaisons de ceux-ci. L'invention porte sur une formulation adhésive à viscosité inférieure et à teneur élevée en matières solides. La présente invention porte également sur un composite et sur un procédé de fabrication d'un composite comprenant un substrat et la composition adhésive de la présente invention.
