Definición
A barrier layer, or coating, is a reversible bond applied as a film between an irreversible adhesive and the surface it is mated to. In paper conservation, for example, a barrier layer is a thin film, such as gelatin or methylcellulose, deposited between the original paper surface and inpainting media applied to compensate for loss or damage. Such barrier layers allow for reversibility of the inpainting treatments.
