How to use

• The adhesive surface must be clean and dry without grease or dust. Wipe the surface with anhydrous ethanol or isopropanol and let it dry for 3-5 minutes.
• Shake 906G until you can hear the balls in the jar rolling freely. Continue shaking for 1 minute then apply the base coating evenly to the surface.
• Drying time for the base coat: 10-30 minutes, depending on the ambient temperature, then start sizing.
• Optimal construction environment: 15~25°C ventilation environment.

Typical applications

• Glass bonding operations
• Glass or ceramic printing edge
• Partial metal processing
