HumiSeal UV40 Gel is a high-solids, single-component UV curable gel. It is engineered as a damming or support material for use with other conformal coatings.

Key Features of HumiSeal UV40 UV Curable Gel

• 50,000 cPs viscosity
• Instant UV cure
• Perfect for damming and keep-out zones

Stays Where You Put It

With an extremely high viscosity of 50,000 cPs, the gel stays exactly where it is dispensed. As a result, it is ideal for sealing connectors, creating keep-out barriers or reinforcing large components.

Fast, Complete Curing

The gel cures instantly under UV light to give a stable, tack-free finish. In addition, a secondary moisture-cure mechanism cures any unexposed areas within 7 days.

Easy Inspection

Like the rest of the UV40 range, the gel fluoresces under UV light. So you can quickly check its placement and coverage.

Why Choose This UV Curable Gel?

UV40 Gel is essential for complex assemblies where liquid coatings might flow into sensitive areas. For example, it can stop coating from reaching connectors or test points.

It also adds mechanical stability to larger parts. That makes it a high-strength tool for specialised electronic protection.

Because it pairs well with other HumiSeal coatings, it fits easily into your existing coating process. You get better control over where coating goes, with less masking work.
