Epoxy potting compounds are essential in protecting sensitive electronic components, power modules, and optical assemblies from mechanical stress, moisture, and thermal cycling. Most commercial potting systems are based on Diglycidyl Ether of Bisphenol A (DGEBA) resins with a combination of fillers, catalysts, and thermal curatives. The choice of curative has a profound impact on both the processing window and the long‑term performance in service. Among the options available, dianhydrides such as 3,3′,4,4′‑Benzophenonetetracarboxylic dianhydride (BTDA®) offer [...]

Epoxy resins are widely used in structural, electrical, and protective applications because they offer strong adhesion, chemical resistance, and thermal stability. Yet many epoxy systems are inherently brittle, especially when cured with high-temperature thermal curatives. For that reason, toughening agents are often added to create a better balance between toughness and heat resistance. Kaneka's KANE ACE™, for example, is marketed as a liquid impact modifier that improves fracture toughness and endurance without losing heat resistance, [...]

Relaxation (or clarification) of EU PFAS policy has reopened commercial and technical interest in high‑performance polyimides, particularly 6FDA‑based systems, by removing some regulatory uncertainty that had stalled development programs and supplier engagement. For several years firms delayed or slowed work on fluorinated polymers because of the wide‑scope ECHA PFAS restriction proposals and the risk of downstream market disruption; clearer regulatory signals now encourage materials teams to re‑evaluate 6FDA polyimides for demanding electronics and composite [...]
