Coalescents used in latex paint are known to contribute to VOC (volatile organic compounds) content, and can also contribute to the odor of a recently dried coating. With the more stringent environmental regulations that formulators must accommodate, there is a need in the industry for a highly efficient, low odor and VOC coalescent. Recently, 2-ethylhexyl benzoate, a new benzoate ester that is low in odor and lower in VOC than the com. coalescent 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (abbreviated TMB), was evaluated as a latex paint coalescent. The 2-ethylhexyl benzoate was evaluated for function in the following types of latex paints: contractor and high quality interior flats, an interior semigloss, an interior gloss, and exterior flat paints. The 2-ethylhexyl benzoate was compared to TMB in paint formulations at equal and low (-25% by weight) levels of the control coalescent. The evaluation specifically focused on the effect of coalescent on tests relating to coalescent function such as low temperature film formation and scrub resistance. The results indicated that the 2-ethylhexyl benzoate performed as well, or better than TMB coalescent, and was more efficient. In addition to being an effective and efficient coalescent, the 2-ethylhexyl benzoate is low in odor (neat and in room after paint application), and has a lower VOC that the TMB. The new coalescent offers the latex paint formulator an efficient raw material for the development of low odor and lower VOC latex paint. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Computed Properties of C15H22O2).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Computed Properties of C15H22O2
