“…Pure poly(vinyl acetate) resin is a clear and colourless liquid which is insoluble in water, aliphatic hydrocarbons, waxes, and fats, but it is soluble in some organic solvents, such as ketones, esters, alcohols, and aromatic hydrocarbons [30]. The polymer in its pure form does not have robust inherent mechanical properties and flexibility [51]. As with acrylics, poly(vinyl acetate) is a thermoplastic material, meaning that ambient temperature influences physical properties such as softness and flexibility.…”

Since their development in the 1950s, poly(vinyl acetate) [PVAc] paints (also known as vinyl) have been used by many artists, most notably in countries such as Spain, Portugal, and the United Kingdom; they are also used globally as a common binder for house paints. However, only a relatively limited number of heritage scientific studies have focused on vinyl paints. Consequently, many critical aspects of this material, such as the degradation processes, variations in paint formulations, and responses to conservation treatments, remain largely understudied. This article aims to summarise the available relevant information on poly(vinyl acetate) paints from both the scientific and the conservation practice perspectives. The article provides a brief overview of the development of poly(vinyl acetate) paints as artist-grade and household products and the known differences in their formulations. It also focuses on poly(vinyl acetate) ageing behaviour, the physicochemical properties, the recent scientific research on poly(vinyl acetate) material characterisation and degradation, and the main conservation issues regarding these paints, such as those relating to cleaning treatments.

“…Por un lado, durante el proceso de polimerización de la resina y por otro, para aglutinar cargas y pigmentos en la fase acuosa (De Sousa Ramos Félix Silva 2011). Debido a su naturaleza hidrófoba, los humectantes permiten emulsionar las partículas sólidas de polímeros y pigmentos en agua, mientras que los dispersantes evitan que estas partículas floculen o formen agregados, manteniendo una dispersión homogénea de la emulsión (Belaroui et al 2003).…”

“…Tanto humectantes como dispersantes se introducen en cantidades considerables en dos momentos de la formulación. Por un lado, durante el proceso de polimerización de la resina y por otro, para aglutinar cargas y pigmentos en la fase acuosa (De Sousa Ramos Félix Silva 2011). Debido a su naturaleza hidrófoba, los humectantes permiten emulsionar las partículas sólidas de polímeros y pigmentos en agua, mientras que los dispersantes evitan que estas partículas floculen o formen agregados, manteniendo una dispersión homogénea de la emulsión (Belaroui et al 2003).…”

“…Both wetting agents and dispersants are introduced in considerable quantities at two points in the formulation. On the one hand, during the resin polymerization process and on the other, to blend fillers and pigments in the aqueous phase (De Sousa Ramos Félix Silva 2011). Due to their hydrophobic nature, wetting agents allow emulsifying solid particles of polymers and pigments in water.…”

Las pinturas acrílicas en emulsión acuosa se han utilizado en el arte de forma masiva desde los años 60. Sus propiedades ópticas y versatilidad posibilitaron su rápida incorporación al ámbito artístico, convirtiéndola en una de las técnicas más reconocibles a nivel internacional. Desde entonces, muchos artistas se han servido de estos productos sintéticos y sus derivados para realizar sus obras, conformando un gran acervo en fondos y colecciones que hoy en día presenta problemas de conservación. Lo más grave de esta situación es que los problemas identificados están intrínsecamente relacionados con su composición y propiedades de envejecimiento. En general, las películas acrílicas son muy sensibles a los solventes orgánicos y el agua, por lo que los métodos de limpieza tradicional no son adecuados para su intervención. Esta publicación pone en contexto parte relevante de la literatura científica referente a los nuevos métodos de limpieza basados en sistemas acuosos y gelificados.
