Technical Datasheet | Supplied by Evonik
Pyromellitic dianhydride. Acts as a curative for epoxy resins. It has low mix viscosity which helps in an easier incorporation of additives. Has a variable pot life for optimal processing and variable cure schedules to accommodate existing heating equipment. Provides optimum purity and particle size to meet specific requirements. Boosts the heat resistance of adhesives. Adhesives incorporating JAYHAWK™ dianhydrides exhibit the dimensional stability, adhesion and heat resistance required for the increasing design complexity of smartphones and tablets. It is a white/off-white colored powder. Can be used in admixtures with other anhydrides. Sensitive to acid formation in the presence of moisture. Exposure to air should be minimized in order to avoid quality and processing variations. Listed in TSCA.

Hansen Solubility Parameters

[22.5, 19.7, 10.2]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with JAYHAWK™ PMDA Ultrapure. A practical determination of these HSP values would provide higher certainty. Learn More.
