Just how low the VOC level needs to be for a given product to qualify for inclusion in GreenSpec depends on the product category. For most products, we require certification to California’s health-based emissions standard, CDPH Std Method v1.1 standard (also referred to as California Section 01350), which tests a product’s resultant VOC concentrations in the space after a given period of time. For wet-applied products like paints, caulks, and adhesives, we still also look for VOC content instead of, or in addition to, verified low emissions; this is because emissions testing doesn’t adequately test initial offgassing, and VOC content is currently the only widely available proxy.
Included here are various erosion-control products, foundation products that eliminate the need for excavation, and exterior stains that result in lower VOC emissions into the atmosphere. Fluorescent lamp and ballast recyclers and low-mercury fluorescent lamps reduce environmental impacts during maintenance and disposal of luminaires.
Kaufman Products offers several low-VOC industrial concrete curing and sealing compounds. Thinfilm 422 Wax Base is a zero-VOC water-emulsion membrane compound formulated especially for highways, but also appropriate for driveways, sidewalks, curbs, and gutters; available pigmented or clear in pails, drums, and bulk. Krystal 15 emulsion EF and Krystal 25 emulsion EF are water emulsion acrylic polymer curing and sealing compounds with 9 g/l VOC, available in drums and pails.
Concrete curing agents are coatings or admixtures that aid the set and cure of freshly poured concrete. They generally use coalescing agents to retard evaporation. Conventional products use a petroleum hydrocarbon resin base.
GreenSpec lists products made with biobased materials, low-solvent, low-VOC (50 g/l or less), water-based, or some combination of those.
