How to use transparent potting glue for photovoltaic panels

6 FAQs about [How to use transparent potting glue for photovoltaic panels]

Can you use liquid adhesive on a junction box?

Moisture intrusion into the electrical connections within a junction box can cause tremendous damage. Liquid adhesives can be used with junction boxes for both potting and mounting and sealing. Silicone RTV is a traditional potting and mounting adhesive, applied both manually or as part of an automated dispensing process.

Do Solar junction boxes need silicone sealants?

Your solar projects deserve silicone sealants and adhesives that stand the test of time, and the elements – especially for long-lasting bonding of solar photovoltaic junction boxes. Unlike other PV tapes, our silicone sealants have proven long life spans, providing reliable sealing in addition to effective adhesion.

How to choose a solar panel junction box?

It is important to check compatibility of all the elements of the junction box including wire, solders, solder fluxes, metals and the exterior sealant applied to adhere the junction box to the back of the solar panel.

Does high humidity affect PV junction box adhesives/sealants?

The PV junction box adhesives/sealants will cure faster and have a shorter working time in higher relative humidity environments. Excessively high humidity (>80%) could cause condensation on the substrate surface and adversely affect material adhesion.

How do PV junction box adhesives/sealants cure?

PV junction box adhesives/sealants cure by reaction with water vapor in the air. The cure reaction progress deeper into the joint by diffusion of water vapor. Typical cure times range from 24 hours to 14 days depending on the cure depth.

What UL testing does fortasuntm PV junction box adhesive / sealant undergo?

As outlined above, all FortasunTM PV junction box adhesives/ sealants have or will undergo the standard UL746 electrical testing known as HWI (hot wire ignition), HAI (high current arc ignition) and CTI (comparative tracking index). Consult the UL website to see the testing result on the potting materials.
