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.

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.

Are fortasuntm PV junction box adhesives/sealants good?

When FortasunTM PV junction box adhesives/sealants are properly applied, they will provide excellent long-term adhesion and durability. FortasunTM two-part PV junction box adhesives/sealants require correct mixing by the sealant user to achieve intended performance.

How long does a PV junction box adhesive take to cure?

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. All PV junction box adhesives/sealants, whether one- or two-part, require exposure to atmospheric moisture to cure.

What are junction box encapsulation materials?

When it comes to junction box (J-box) encapsulation materials, we understand the importance of providing a low cost, proven solution. The polyurethane and epoxy resins we formulate keep your products protected from moisture and demonstrate great hydrolytic stability in many different temperature environments.

What type of polymer is used to make junction boxes?

Polycarbonates and polymer blends such as polyphenylene oxide (PPO) and polyphenylene ether (PPE) are typically used to manufacture junction boxes. Each of these types of boxes is versatile, resistant to acids and possesses high dimensional stability and dielectric strength, as well as low moisture absorption.
