I am confused how to identify if this products should be considered as Adhesives and Sealants or Paints and Coatings. Need your advise please. Thank you.

“Dry Pre-Mix Mineral Based Bonding Coat” appears to refer to a plaster product applied over smooth concrete to provide a roughened (keyed) substrate for subsequent layers of plaster. As such, the product probably does not qualify as a coating under IEQc4.2. However, if the plaster base contains organic binders, polymers, or additives, adhesive VOC limits specified under IEQc4.1 could apply. Check material safety data or ingredient lists to verify the composition of the plaster. If the plaster contains only inert mineral components such as gypsum & Portland cement, VOCs should not be a concern.
However, to be safe, you could enter this product into the IEQc4.2 template as a "Primer" with a VOC limit of 200 g/L or a "Mastic" (300 g/L, max.) if it meets either definition under SCAQMD Rule 1113.
If the product forms a substrate for materials other than plaster, it might qualify under IEQc4.1 as a "Ceramic Tile," “Drywall”, “Panel,” or "Structural Glazing" adhesive if it meets any of these definitions under SCAQMD Rule 1168.
