The use of synthetic silicone pressure-sensitive adhesives (PSA's) in the restoration of paintings without vacuum or surface pressure or excess heat is described. A brief review of the manufacture, application and physical properties is given. The PSA's are made from inert high molecular weight silicone gum and a silicone resin. The ratio of gum and resin varies the physical properties such as tackiness. A recent application of a silicone adhesive developed by Robert E. Fieux is a painting lining material Fabri-Sil, using a DuPont Teflon TFE fluorocarbon resin coated fiberglass and a fully cured crosslinked General Electric silicone adhesive on one side. Lining involves contact but no heat or pressure and is removable with solvent naphtha. The use of liquid silicone adhesive for paint consolidation by electrostatic deposition on an electrostatic hot table is described. The use of silicone-coated temporary reinforcing tissue or fabric for mending tears and punctures is also reported. -- AATA
