The assemblage of PV modules frame and laminated pieces must be connected closely and reliably with good sealing function against liquids and gases corrosion.
The Junction box and the back plates should have good adhesion and would not fall off even under stress partly in long time.
709 is designed for the bonding of the solar PV module aluminum frame and the junction box. This product, neutral cured, has excellent adhesion, excellent aging resistance, and could prevent the penetration of gases and liquids effectively.
