EAA (99%) is a low-color, low-viscosity liquid used in various applications, including as a copromoter for unsaturated polyester resins.
EAA (ethyl acetoacetate, CAS number 141-97-9) is a low-color, low-viscosity liquid 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 used as a chemical intermediate and stabilizer for fragrances due to its lower color and pleasant odor, and as an intermediate for agricultural and pharmaceutical applications.
