Green Seal, an independent nonprofit certifier of sustainable products and services, has introduced a revised version of its GS-11 Standard.
The updated standard covers most types of architectural coatings. This new edition of GS-11 includes floor coatings, concrete and masonry sealers, and fire resistive coatings, in addition to the paints, primers, anti-corrosive coatings, and reflective coatings previously covered. The new Green Seal standard offers greater flexibility for the assessment of VOCs and aligns with VOC limits set by the current California Air Resources Board. The standard also addresses:
- Stains and finishes for wood and metal, previously covered by the GS-47 Standard
- Updates for clarity on certain criteria for chemical ingredients, reflecting the current market for leadership products
With the rapid advances in formulation technology Green Seal redesigned GS-11 to promote the creation of safer coatings by restricting a comprehensive list of harmful chemicals, including heavy metals, certain phthalates, formaldehyde donors, carcinogens, mutagens, reproductive toxins, hazardous air pollutants, and ozone depleting compounds. Exceptions are made for titanium dioxide, carbon black, crystalline silica, and PCBTF because they are necessary for acceptable performance and feasible alternatives are currently lacking.
