Hygrothermal ageing of dry gelatine adhesive films: Microstructure-property relationships

Gelatine adhesives, also known as animal glues, are collagen-based water-soluble biopolymers derived from vertebrate connective tissues. One of the various fields in which gelatine adhesives are widely used is the conservation of cultural heritage such as decorated furniture and panel paintings. It is observed that, with time, the failure in...

Time to failure analysis of wood adhesives: a non-linear approach based on chemical reaction kinetics

Similar to wood, adhesives may exhibit duration of load effects. When loaded for longer periods of time, damage processes in the material may develop, eventually leading to failure. From wood research it is known that load level, temperature and relative humidity have an important influence on this behaviour. In general, higher stress levels,...

Gelatine adhesives from mammalian and fish origins for historical art objects conservation: How do microstructural features determine physical and mechanical properties?

Gelatine adhesives aka ‘animal glues’ are water-soluble biopolymers used in historic objects such as wooden cabinets and panel paintings since ancient times. This paper investigates the correlations between microstructural features, namely triple helices, and macroscopic properties of four different types of gelatine adhesives, prevalently...

Collagenous Bioadhesives: Structure-Property Correlations and Hygrothermal Ageing

Collagen-based bioadhesives, also known as animal glues, are derived from animal parts (e.g. skin, bone, and cartilage). They have been widely used in the production of decorative wood working, paintings, bookbinding, and other historical objects for centuries as well as for their restoration and preservation [1]. <br/><br/>Collagen, in which...

Ageing phenomena of oak wood-animal glue bonded assemblies for preservation of cultural heritage: Poster presentation

The structural preservation of panel paintings and decorated furniture as significant parts of Dutch cultural heritage, requires comprehensive knowledge on the long term behaviour of their constituent materials namely wood and animal glues. A decorated cabinet crafted by Jan van Mekeren (1684-1744) is chosen as the case study. The environment...
