What are photovoltaic tapes used for?

Photovoltaic tapes for the renewable energy market for bonding, venting, insulation, protection & masking. Custom rolls & die-cut shapes available.

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.

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.

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.

Where can I find a technical sheet for a photovoltaic cartridge?

An available technical sheet contains the many details of proper cartridge use. The document (Form No. 06-1051*-01) can be found at photovoltaics.dupont.com. (Note, * represents an alpha character, which indicates the document version.)
