  • Applications

    Compound 3,9-Bis(2-(3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propionyloxy)-1,1-dimethylethyl)-2,4,8,10-tetraoxaspiro(5.5)undecane (CAS 90498-90-1) is typically explored as a crosslinking/curing agent for epoxy and other polymer systems in coatings and adhesives; the bis(ester) and spiro-orthoester functionalities enable network formation and controlled release behavior in formulated resins. The hindered phenolic moiety can act as an antioxidant/thermal stabilizer, so the compound may be used as a stabilizer additive in polymers, plastics, and lubricants. It may serve as a reactive component in UV-curable coatings and inks, contributing to cure efficiency and network density. It also has potential as an intermediate in the synthesis of specialty polymers or resin systems for electronics encapsulation and packaging, and in industrial manufacturing formulations requiring crosslinking/stabilization. Use is subject to local regulations and formulation limits.
