Product Details
Hexahydro-4-methylphthalic anhydride (HMPA) is a versatile organic chemical compound that has been widely studied in the scientific community due to its many potential applications. This substance is used in formulation or re-packing, at industrial sites and in manufacturing. Hexahydro-4-methylphthalic anhydride (MHHPA) is a colorless and transparent liquid and has the advantage of ease of handling in the curing process.
InChI:InChI=1S/C9H12O3/c1-5-2-3-6-7(4-5)9(11)12-8(6)10/h5-7H,2-4H2,1H3
The capabilities and performance of γ-titanium phosphate (γ-TiP) with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as a latent thermal catalyst were investigated by the copolymerization of glycidyl phenyl ether (GPE) and hexahydro-4-methylphthalic anhydride (MHHPA) at different temperatures for a period of one hour.
We have cured these two fluorine-containing CAEs, using hexahydro-4-methylphthalic anhydride (HMPA) and compared them with a commercial CAE, 3,4-epoxycyclohexylmethyl-3,4-…
