Resumo
The preservation of cultural artifacts, particularly those made of wood, is a
significant concern for conservators due to their susceptibility to damage from
xylophagous organisms, fungi, and bacteria. This study investigates the use of gamma
radiation to cure polymeric resins for the consolidation of three wood species: cedar
(Cedrela spp.), canafistula (Peltophorum dubium), and ivorywood (Balfourodendron riedelianum).
Various resins, including polyester LP 8847® combined with styrene, were subjected to
gamma radiation to induce cross-linking without the need for catalysts. The results
demonstrated that gamma radiation effectively cured the resin, filling wood pores and
enhancing structural integrity. The analysis of apparent density showed that cedar,
canafistula, and ivorywood exhibit different absorption capacities, with cedar absorbing
the most resin and canafistula the least. Optical and Scanning Electron Microscopy
confirmed the efficient penetration of resin into the wood samples, indicating that gamma
radiation can be a viable technique for wood consolidation and protection against
degrading agents.
