Pittcote, Pittseal and CS White Paint: Product History
Separate Pittsburgh Corning accessory coatings and mastics from Unibestos thermal pipe covering.
A different product family
Pittsburgh Corning interrogatory responses separately identify Pittcote, Pittseal and CS White Paint as accessory products. The company stated that some formulations at certain times included small amounts of asbestos fiber as a binder.
What the materials were used for
The company described these accessories as mastics or coatings, not Unibestos high-temperature pipe insulation. The distinction between a coating pail and a rigid pipe-covering carton is useful when reconstructing a work history.
Product name plus formulation date
The company stated that accessory formulations changed over time and that some asbestos-containing versions were last sold in the mid-1980s. A remembered product name should be paired with the date and the particular formulation.
Practical memory clues
Recall a pail, brush, coating surface, label, manufacturer or contractor. Do not merge accessory mastics and Unibestos pipe sections into one product category.
