Product overview
Hexahydrophthalic Anhydride is a low-color cycloaliphatic anhydride used in epoxy curing, electrical casting and electronic encapsulation where thermal and electrical performance are important. Moisture control and grade-specific curing evaluation are essential.
Function & Usage
- Repel Water & Hydrophobize Surfaces
Reduces water uptake or increases surface hydrophobicity in suitable mineral, masonry, concrete or coating systems. Typical uses: Epoxy coatings and casting compounds, Electrical impregnation and encapsulation, Electronic and integrated-circuit packaging.
- Encapsulate, Pot & Electrically Insulate
Supports potting, casting, molding or encapsulation systems used to protect and electrically insulate components. Typical uses: Epoxy coatings and casting compounds, Electrical impregnation and encapsulation, Electronic and integrated-circuit packaging.
- Cure & Accelerate Electronic Epoxy Systems
Provides curing or catalytic activity for epoxy systems, with latency, cure speed and thermal performance selected by formulation. Typical uses: Epoxy coatings and casting compounds, Electrical impregnation and encapsulation, Electronic and integrated-circuit packaging.
- Build Industrial & Protective Coatings
Provides a binder, pigment, curing or performance function for compatible industrial and protective coating systems. Typical uses: Epoxy coatings and casting compounds, Electrical impregnation and encapsulation, Electronic and integrated-circuit packaging.
