H.B. Fuller EA6405 UV/Thermal Dual-Cure Adhesive
H.B. Fuller EA6405 is a white/beige UV/thermal dual-cure adhesive with very high viscosity and thixotropy, so tall beads hold their shape after dispensing.
- Dual-cure chemistry: UV light for fast fixing, followed by heat for full cure
- High thixotropic index (TI) for dispensing high-aspect-ratio beads
- Low-temperature thermal cure, down to 70°C
H.B. Fuller EA6405 is a white/beige UV/thermal dual-cure adhesive with very high viscosity and thixotropy, so tall beads hold their shape after dispensing. It fixes under UV, completes its cure with low-temperature heat and bonds well to plastics and metals, making it a fit for image sensor assembly. FEYANA supplies H.B. Fuller EA6405 together with technical documentation and application selection support.
