MPI, developer of architectural paint standards, has announced updates for a variety of its standards, including several relating to recycled paints.
The organization, based in Canada, also develops quality assurance programs for North America.
The new revisions include updating the Recycled Paint Standards to eliminate Clause 4.3 on reflectance. All clause numbers and referrals have been changed appropriately for these standards:
• #53 RC Latex, Recycled (Consolidated) Interior Gloss Level 1
• # 53 RR Latex, Recycled (Remanufactured) Interior Gloss Level 1
• # 54 RC Latex, Recycled (Consolidated) Interior Gloss Level 5
• # 54 RR Latex, Recycled (Remanufactured) Interior Gloss Level 5
MPI standards distinguish between "Remanufactured" (RM) and "Consolidated" (RC) recycled paints. Consolidated paints are produced by the collection and consolidation of post-consumer latex paint, repackaged without modification of paint properties by a paint manufacturer. They contain a minimum of 95% post-consumer paint and maximum 5% secondary or virgin materials.
On the other hand, remanufactured paints use less post-consumer waste (minimum 50%) with a maximum of 50% secondary or virgin materials. This enables the manufacturer to better control color, include desirable additives, and incorporate more formulation skill.
“Specifiers can rest assured MPI-approved recycled paints meet the same stringent requirements as our virgin paints,” an MPI statement says. For example, it adds, “a product approved under MPI 44RC met the same requirements as MPI #44 for adhesion, hiding power, ease of application, water resistance, weathering, etc. “
In fact, MPI reports far stricter confirmation demands for recycled paints than it does for virgin paints.”While virgin paint must be re-tested every two years, recycled paints are retested bi-annually or even quarterly depending on the standard, and an annual audit of the manufacturing facility is also required,” the organization says.
For that reason, MPI says, its approved recycled latex paints “can be a viable choice” for projects but “may enable a specifier to get a LEED credit for recycled content.”
Recycled paints are now available in a range of colors and properties, and are often sold at lower prices than comparable virgin paint, MPI notes.
MPI standards offer recycled versions of MPI 10 latex exterior flat and MPI 15 latex exterior low sheen (gloss levels 3-4); for interiors, the organization offers recycled versions of MPI 44, 52, 53, and 54 "conventional" latex standards in Gloss Levels 1, 2, 3, and 5 (semi-gloss).
The other updated standards:
• Intended Use. The new standard reduces to 85% the percentage of zinc required in MPI 18 Primer, Zinc Rich, Organic and MPI 19 Primer, Zinc Rich, Inorganic . In addition, MPI #36 Sealer for Knots now permits either clear or pigmented sealers.
• MPI #133 WB Dry Fall for Galvanized Steel, Flat. The changes include extending the dry time before testing as well as the adhesion testing procedure.
