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Camger was originally made in two different formulations: Polyglase 1-175 and 1-146. 1-175 was the formulation that was originally developed and tested for conservation use, but 1-146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.

Instructions for use: Mix well before using. This product is made ready to use. If thinning is necessary use small amounts of water. It can be applied by either spraying or brushing (with a foam brush). Two coats are recommended for protection. Sanding is recommended between coats. It is difficult to work with and does not produce a very smooth layer.
Typical dry times are 2-3 hours, but full-cure can take up to a week to harden from a soft coating. It is prone to cracking and breaking if not applied correctly.
Previously used as vapor barrier, but requires up to 4 or more coats to provide protection. It is more paintable than Marvelseal.
No special requirements for storage or handling.
