Camger 1-175 Polyglase Environmental Coating
[Camger Coating Systems Inc.] A protective coating formulated with an aliphatic urethane and poly(propylene glycol). Camger 1-175 is designed to provide a barrier coating to minimize off-gassing. The preparation does not contain any solvents and the dried coating is resistant to abrasion, chemicals and hydrolysis.
Camger was originally made in two different formulations: Polyglase 1-175 and 1-146. 1-175 was the formulation that was originally developed and tested for conservation use, but 1-146 was very similar in formulation and cost. For a period the company kept 1-146 but discontinued the 1-175, then later restarted production of 1-175 by repurposing Sancure 878. Camger 1-175 has shown excellent adhesion properties to a wide variety of substrates such as, solid woods, particleboard, Medite II.
