Moisture-cure aromatic elastomeric coatings also are used in deck and waterproofing applications such as secondary containment, below-grade waterproofing, and parking garage and deck waterproofing. In these applications, the reflective pigments are not needed, but a pigment often is used to track coverage...

Ideally, a clean metal surface is free from a water layer below the dewpoint. However, in actual conditions, water condensation occurs...

..., respectively. For example, a typical plasma spray powder may be defined as –325 mesh +10 μm (10 to 44 μm). This powder by normal definition would have a minimum of 80% of its particles between 10 and 44 μm, allowing for up to 10% below 10 μm and 10% above 44 μm. The assumption is that the powder is normally...
