Impregnant formulation to the preservation, protection and consolidation of wood heritage assets

Abstract

The protection of cultural heritage is an integral part of the world´s material wealth. The cultural heritage, movable and immovable, together with the natural environment, represents values that contribute to the education and social culture of the community. It also has a significant economic impact because, it represents the basic prerequisite for a tourism industry. Therefore, the modern developing based on non-polluting technological products for the protection of patrimonial is needed. Also, it is necessary to build a bridge between the basic knowledge generated as a product of scientific research and applied science. The knowing of what kind of deterioration occurs and how it impacts the physical-mechanical properties of the materials are important issues and, that must be considered so that the constructions made can be adequately conserved and/or consolidated. Wood was treated with an innovate formulation based on silanes (methyltriethoxysilane, MTES and noctyltryethoxysilane, OTES) to achieve the protection and the consolidation of the heritage assets. The performance of treatment about dimensional stability, fire and biodeterioration/biodegradation resistance was investigated. It was concluded that the treatment resulted effective as a protective and consolidate lasur system based on silanes by surface treatment for wood heritage assets.
