Common Questions

FAQs — PR-338

What is PR-338 used for?

Solar PV panel frame sealing, photovoltaic installation joints, solar farm infrastructure sealing, and renewable energy equipment sealing.

Does it resist UV without chalking?

Yes — UV resistance is the primary design requirement for this grade. It is formulated to resist UV degradation without chalking or losing elasticity, and we can supply the test evidence we hold for your project file.

Can it be used on anodised aluminium frames?

Yes, PR-338 is neutral cure, so no acetic acid is released to attack anodised aluminium or the module edge seal. Adhesion should still be confirmed on the actual frame finish used on your project.

How long will it last on a solar installation?

It is formulated for long-term outdoor exposure, but the honest answer depends on your climate and mounting system. Ask us for the ageing data we hold and compare it with your project expected service life rather than relying on a single number.

What is the MOQ and lead time?

Standard OEM and private label MOQ is 1,000 pcs per model, with mixed-model trial orders from 3,000 pcs total and stock items from 500 pcs. Typical lead time is 15–25 days after artwork and sample approval.
