LOCTITE STYCAST S 5225 is a two-component, low-viscosity silicone encapsulant designed for potting and encapsulating small electronic devices. It features primerless adhesion when heat-cured and meets UL 94 V-0 flammability standards.
Key Benefits:
✔ Very low viscosity for easy flow
✔ High-temperature resistance (-60 to +220°C)
✔ Simple 1:1 mix ratio (by weight and volume)
✔ Primerless adhesion for fewer processing steps
