Abstract
The use of certain siloxane and silane materials for the conservation of organic and inorganic materials. More specifically, this invention deals with a method of impregnating organic and inorganic materials with siloxanes and silanes and ultimately curing such materials to provide preservation properties to such materials. An especially significant use of the method is to preserve and conserve ancient artifacts. The curable materials are represented by silanol containing polymers crosslinked with trialkoxysilanes.
Claims1
A method of conserving materials comprising impregnating a material selected from the group consisting of animals, reptiles, animal and human body organs and bones, leather, pelts, and hides with a curable polymeric system comprising (i) a siloxane polymer having an average of at least two silanol groups per molecule, (ii) sufficient of a crosslinker to crosslink a significant portion of the siloxane polymer, and curing the impregnated material with the crosslinker in (ii), the crosslinker being selected from the group consisting of R″Si(Oxime)3 and Si(Oxime)4, wherein R″ is a phenyl group, hydrogen, a vinyl group, or an alkyl group having 1-12 carbon atoms.
