Abstract
The invention relates to application of solvent(s) to a product including at least one binder, wherein the product is a paint or coating formulation and the solvent is a compound of renewable vegetable origin, notably agricultural origin. It also relates to a paint or coating including at least one binder and one solvent, wherein the solvent is of renewable vegetable origin. Formulations are given.
Claims17
Paint, coating or varnish comprising at least one binder and at least one solvent in its formulation, the solvent(s) being compounds derived from renewable resources of vegetable or animal origin, and preferably of agricultural vegetable origin, including silvicultural and aquacultural origin, the binder being chemically inert in the formulation, the solvent(s) taking part in the setting of the paint or coating through evaporation or through siccative action according to the case, while being compatible with the rest of the formulation, characterized in that it comprises:
- at least one inert binder and at least one plasticizer, the solvent(s) and additive(s) and possible pigment(s).
A method for preparing a composition of the paint, coating or varnish type from an initial formulation comprising at least one binder, the formulation further comprising at least one solvent of petrochemical origin, the binder being chemically inert in the formulation,
- characterized in that the solvent(s) of petrochemical origin are substituted by a solvent derived from renewable resources of vegetable or animal origin, and preferably of agricultural vegetable origin, including silvicultural and aquacultural origin, the solvent being compatible with the rest of the formulation, the solvent(s) derived from renewable resources taking part in the composition through evaporation or through siccative action according to the case.
