The product seems to be a “Panel Adhesive”.
Indoor Environmental Quality Credit 4.1 defines categories of adhesives based on Rule 1168 of the South Coast Air Quality Management District (SCAQMD).
By this definition, a “Panel Adhesive” is “an adhesive used for the installation of plywood…and similar pre-decorated or non-decorated panels to studs [framing] or solid surfaces.”
For Panel Adhesives, the VOC Content must not exceed 50 grams per liter.
For primers and paints, see categories defined under Indoor Environmental Quality Credit 4.2.
The VOC limit will depend on whether you are using opaque paints or clear wood finishes.
