Objective:
The aim of the project is to develop an industrially producible bio-sourced varnish based on gum rosin and linseed oil, inspired by the ancient know-how of the violin maker Antonio Stradivari (1644-1737). The difficulty is to meet the specifications of an industrial manufacture while achieving high performance of the varnish.
Context:
The context is twofold. On the one hand, the need to develop a local resource, the maritime pine resin, which is no longer exploited today, with the desire to participate in the revival of a whole sector in the south-west of France, which goes from the extraction to the development of the resin. On the other hand, the aim is to develop a new biosourced varnish that can be industrialised and thus meet the growing societal demand.
