Devcon EP8500HF Transparent Epoxy Potting Compound
Devcon EP8500HF is an advanced two-component, transparent epoxy designed specifically for internal potting and casting in sensitive electronic devices like smart rings. This halogen-free, anti-yellowing formulation ensures excellent optical clarity (transmittance >99% at 550-1000nm). It cures at a low temperature of $60^{\circ}\text{C}$ in 6 to 8 hours, offering a long 100-minute working time and low mix viscosity (200-400 cps). EP8500HF provides a balance of toughness and softness, achieving a Shore Hardness of 65D with a high elongation (20-30%). It is also biocompatible, having passed GB/T 16886.10-2017 and ISO 10993.5-2009 certifications. The stable 4%-5% shrinkage rate helps avoid cracking problems.
