Resumo
Preservation consists of an action that aims to guarantee the integrity
and perpetuity of something, such as a cultural asset. One of the preservation
instruments is restoration, an intervention that aims to definitively secure a
product of human activity. Cultural heritage presents an extensive diversity of
wooden objects, which can be affected by insect attacks, causing severe damage
to their structures. To recover this damage, compatible materials are needed to
maintain their integrity. Therefore, we propose to study the obtaining of
polymeric resins cured by gamma radiation without the use of catalysts for
consolidation or restoration of wooden objects. A series of formulations were
developed with polymeric resins based on paraloid B72 and polymeric
monomers cured by gamma radiation from a cobalt-60 source. These resins
were characterized by physicochemical analyses, and the results presented were
surprising in terms of reversibility. Gamma radiation replaced the catalyst,
curing the resin 100%, indicating new resin options for restoration and/or
consolidation in porous wood.
