London - Suppliers of resins for the woodworking sector are making sure their customers know that materials are available to meet the recently implemented California Air Resources Board (CARB) legislation limiting formaldehyde emissions, which came into effect 1 Jan 2009.
BASF announced 8 Feb that it has introduced Lupranate M20 resins, which contain no added formaldehyde, for the composite wood products industry.
Meanwhile Bayer MaterialScience announced 9 Feb that manufacturers of wood composites can use its Mondur polymeric MDI binder, which is compliant with the newest CARB regulations.
BMS said in a press release that this MDI binder is already replacing formaldehyde-emitting binders in flooring, cabinetry and other furniture uses. "These panel products meet CARB Phase II requirements regarding the level of formaldehyde emissions," BMS said.
And BASF stated that its Lupranate M20 MDI-based resins contain no formaldehyde and do not generate formaldehyde during application, so they are a "viable alternative for composite wood manufacturers seeking a more sustainable way of doing business." BASF said it recently converted a major window and door manufacturer's composite wood operation from formaldehyde-based resin to Lupranate M20 resin.
BMS pointed out that a second phase of the CARB regulations begins in two years time, with tighter regulations on the amount of formaldehyde that particle board, medium-density fibreboard (MDF) and other wood-composite products can emit.
According to BASF, the US Environmental Protection Agency (EPA) has also launched efforts to understand potential health risks associated with formaldehyde emissions and their effect on indoor air quality.
