A Newly-introduced, Low Odor, Amino Alcohol that Helps Enable Architectural Paint Producers to meet 2010 VOC Requirements

Meeting 2010 VOC paint limitations, such as those set in EU Directive 2004/42/EC, can present a challenge for paint producers, especially in terms of product performance. Amino-methyl-propanol (AMP) has a well established history of providing key multifunctional benefits to paint formulations, including neutralizing and dispersion properties, but is classified as a VOC. The necessity for a non-VOC amino alcohol has led to the development of an improved version of amino-ethyl-propan-diol : AEPD VOX 1000. This amino alcohol is a primary amine with improved color and odor properties, low vapor pressure, a high boiling point, a non-yellowing characteristic and is a classified as VOC-free in Europe. Additionally, this new version of AEPD offers the same excellent performance benefits as AMP in terms of co-dispersion efficiency, neutralization, scrub resistance and color stability with the added benefit of an improved odour profile, making it a clear choice as a multifunctional amine for VOC-free paints.

Although similar in structure to AMP, an additional hydroxyl function in AEPD allows for an extension in the open time without impairing the scrub resistance. Additionally, AEPD VOX 1000 has been shown to have significant coalescent properties allowing for reduction in primary coalescent levels and other VOC materials.
