EAA (ethyl acetoacetate) is a 99% purity, low-color, low-viscosity liquid copromoter and intermediate that is readily soluble in water and common organic solvents. Ethyl acetoacetate can be used in multiple applications and is commonly used to replace styrene in unsaturated polyester formulations due to its ability to develop desirable hardness more rapidly. Acetoacetates are typically preferred as copromoters in polymerizing polyester resins for their ability to lower the resin viscosity and polymer Tg and cross-link with other polymers via multiple reaction pathways. EAA is also commonly used as a chemical intermediate and stabilizer in fragrances due to its low color and pleasant odor. It is also used as an intermediate for agricultural and pharmaceutical applications.
