NC-2009 IEQc4.1:Low-Emitting Materials—Adhesives and Sealants

Cleaners

Should a cleaner used before the adhesive (to make the Surface clean) fullfill IEQc4.1? If it should which category should be used?

Cleaners are not covered in LEED.

Absolutely right! A cleaner used simply to prepare a substrate for an adhesive by removing dirt & residue from the surface is not an adhesive or an adhesive primer. By comparison, to improve the bond to some substrates, some adhesives require an adhesive primer or an adhesive bonding primer to prepare the surface. These are not cleaners. They are coatings and adhesives that remain on the surface. SCAQMD-1168 defines these primers as a subset of “adhesives,” so primers use the same VOC limits as the adhesives applied over them. [Exception: Adhesive Primers for Plastic and for Traffic Marking Tape have their own categories.] If your product is just a cleaner, it is not applicable to IEQc4.1. However, as with all chemicals used inside the building, your project’s IEQc3 Construction IAQ Plan should address proper handling and ventilation during use.
