Toluene Diisocyanate (TDI) CAS:584-84-9 TDI (CAS : 584-84-9) is produced by a 3 step reaction. The first step is the nitration of toluene to obtain dinitrotoluene. Second step is the catalytic hydrogenation of Dinitrotoluene into toluene diamine TDA. Finally, the TDA react with phosgene to produce the TDI. TDI is commonly sold under 3 different […]

HexaHydroPhthalic Anhydride (HHPA)
HexaHydroPhthalic Anhydride is a white solid or clear liquid if melted with molecular formula C8H10O3.
HexaHydroPhthalic Anhydride Chemical Structure Composition.
HHPA is mainly used as an intermediate for coating resins (alkyds, polyesters), plasticizers, sealant, curing agent in adhesive, insect repellents, rust inhibitors, electronics applications.
HHPA’s low melt viscosity, as well as its high mix ratio with epoxy resins, makes it particularly suitable as hardener for epoxy resin for applications where high filler loadings are required.
HHPA is preferred over other aromatic anhydrides in casting and coating applications for his higher resistance to yellowing.
HHPA has high-temperature stability, excellent dielectric properties, and high glass transition temperatures.
