Infra-Aid™ is a brand of leak repair products developed specifically for repair and maintenance of infrastructure equipment.
“UVS-1000C” UV curable Sealant
Ideal for emergency repair of oil leaks on electrical equipment or other infrastructure. When applied to oil pipe or flange leaks on aging or deteriorated equipment, it incorporates and integrates surface oil to bond tightly with the part repaired. Instant curing after at least one second of UV exposure stops oil leakage and prevents leak paths from developing.
Bonds even to slightly oily surface
Sealant itself blends with and incorporates residual oil, allowing the sealant to come into contact with the bonding surface of the pipe to ensure adhesion to oily surfaces
Formulated for optimal viscosity when applied
Ideal fluidity to resist sagging on vertical surfaces yet become runny to flow into small gaps
Cures quickly with UV
Effective in preventing leak paths from developing
Significantly saves the working time compared to epoxy-based repair materials
Removable after repair
Sealant hardness is designed to enable removal by chipping
How It Works
Oil leaks : Can be used for infrastructure equipment repair where complete removal of leaking oil or residual surface oil has been difficult.
Electrical equipment: ∙ Transformers ∙ Shunts
Parts where oil leaks: ∙ Flanges ∙ CT-boxes ∙ Bushing cementing ∙ Weld pinholes
2. How to Use
1. Prepare surfaces by removing old paint, rust, and grease
Clean and degrease leaking parts.
Remove paint and rust in advance.
2. Apply the sealant
Apply the sealant to affected parts.
3. Cure with UV exposure
Immediately cure by exposing to UV light.
4. Apply and cure additional coats
Repeat steps 2–3 to apply at least two coats of sealant.

1.Adhesiveness to oily surfaces
Test Piece Condition
Adherend: Stainless steel plate (SUS 304), 1000-grit sanded
Cured sealant: UVS-1000C, 1 mm thick, in a diameter of 6 mm
Shear test speed: 0.2 mm/s
Curing conditions: 1 J/cm2@ 365 nm
Steel plate was immersed in hexane solution containing HV Insulating Oil A.
Prepared with a layer of oil by removing the plate and drying the hexane.
Sealant was applied to the steel plate with oil film and cured by UV exposure.
Strength was measured by scratching the cured part horizontally with a shear tester.
