We call our silicone oil processes Passivation Polymerization because after treatment, artifacts are environmentally stable and not affected by changes in temperature and humidity.

After treatment, the general half-life expectancy for artifacts to remain stable has been calculated using accelerated weathering and computer modeling. Artifacts should remain stable for at least 250 years.

What about Reversibility?

Reversibility of treatment strategies is always desirable. In practice, however, true reversibility is seldom possible. Archaeological chemistry is proving that many of the treatments thought to be reversible in the past are not, since natural crosslinking and chemical bonding occurs between the matrix of the artifact and the material used in the conservation process. Re-treatability may be a better ethical standard for the treatment of the archaeological assemblage.
