MMG Autumn Series: Evaluation of varnish-layer strategies to enhance the durability of Plasticized PVC

This talk evaluates the addition of a varnish layer to slow down the degradation of p-PVC.

When trying to preserve plasticized PVC (p-PVC) objects, conservators are faced with two main degradation phenomena: a yellowing caused by the release of hydrogen chloride from the PVC chains, and the migration of plasticizers.

This loss of plasticizers induces fouling in addition to a loss of flexibility that often leads to tears. This talk evaluates the addition of a varnish layer to slow down the degradation of p-PVC.
