Description
Isononyl acetate (CAS 40379-24-6, EC 254-898-6) is a branched-chain ester solvent commercially available under the trade name Exxate 900, also referenced as 7-methyloctyl acetate or isononyl alcohol acetate. It carries no assigned E-code and belongs to the acetate ester solvent family with the molecular formula C11H22O2.
In coatings and printing inks, isononyl acetate functions as a slow-evaporating solvent that extends open time and improves film levelling, reducing surface defects in high-solids formulations. In adhesives and sealants, it acts as a plasticising solvent, lowering viscosity during application while contributing flexibility to the cured matrix.
Isononyl acetate is supplied in industrial drum and IBC formats and is subject to REACH registration requirements for EU market supply. Procurement teams should confirm supplier SDS documentation and confirm compliance with applicable workplace exposure limits under CLP/GHS classification frameworks before specifying grades.
