Abstract
The present invention relates to a liquid adhesive composition comprising a partly hydrolyzed protein component, having a degree of hydrolysis (DH) in the range 0.2-2; a metal silicate component; optionally, an exogenic protein hydrolyzing component; and wherein the liquid adhesive composition has a solid content in the range 15-80% by weight.
Claims18
A process for at least partly adhering at least two parts together with a liquid adhesive composition, the process comprising:
- placing a liquid adhesive composition having a solid content in the range of 15-80% (w/w) between at least two parts, wherein the liquid adhesive composition is obtained by:
- hydrolyzing a protein component to a degree of hydrolysis (DH) in the range of 0.4-0.7, as measured by the “pH stat” method;
- and
- mixing 10-50% (w/w) of the hydrolyzed protein component with 2-60% (w/w) of a metal silicate component;
- and
- pressing the at least two parts together such that the at least two parts are at least partly adhered together by the liquid adhesive composition.
A process for at least partly adhering at least two parts together with a liquid adhesive composition, the process comprising:
- placing a liquid adhesive composition having a solid content in the range of 15-80% (w/w) between at least two parts, wherein the liquid adhesive composition further comprises:
- 10-50% (w/w) of a hydrolyzed protein component having a degree of hydrolysis (DH) in the range of 0.4-0.7, as measured by the “pH stat” method;
- and
- 2-60% (w/w) of a metal silicate component, wherein the hydrolyzed protein component and the metal silicate component of the liquid adhesive composition are mixed;
- and
- pressing the at least two parts together such that the at least two parts are at least partly adhered together by the liquid adhesive composition.
