LeakAID Q&A

(1) For fuel oils, effectiveness is in the order of heavy oil > diesel > kerosene > gasoline (higher boiling point and viscosity perform better).

(2) For lubricating oils (insulating oil, engine oil, etc.), there are many varieties and performance cannot be generalized. Mineral-based oils generally perform well; synthetic oils are less suitable.

For liquids other than oil such as water, and for gases such as air, fluorocarbons and fuel gases, application may be possible by adjusting the application method.

Strong acids or alkalis may attack the cured sealant, making long-term repair difficult (only short-term emergency repair is feasible).

It will not adhere if moisture remains on the substrate. Since the cured sealant is water-resistant, LeakAID can be used as long as moisture is removed from the substrate surface by wiping or drying with a hot air blower.

Acrylic resin and silica filler.

80°C. However, it does not peel off immediately above 80°C; the resin gradually softens and adhesive strength decreases.

The resin does not melt, but adhesive strength decreases and deterioration accelerates.

Verified by testing down to -20°C; in principle there should be no problem down to around -40°C.

Equivalent to SPSS Grade 2 (St 2) is required. Remove old paint film and rust to expose the bare steel surface.

It will stop the leak temporarily as an emergency measure, but the effective period will be shorter than with proper surface preparation.

The reason is that the adhesion between bare metal and the paint film is weaker than between the sealant and the paint film, so oil with nowhere to go creates an oil path between the bare metal and paint film, often leading to leak recurrence.

Some customers use it as a short-term emergency measure in locations where proper surface preparation is not possible.

It does not adhere to silicone-based or fluorine-based resins. Not recommended for olefin-based resins (polyethylene, polypropylene, etc.) or flexible PVC.

Minimum 1mm per layer. Multi-layer application is recommended: apply and cure at 1-3mm per layer, then apply two or more layers. The final total thickness after layering should be 4mm or more. If a single layer exceeds 3mm, UV may not reach the critical interface between substrate and sealant, risking incomplete curing. Less than 1mm results in insufficient surface curing and reduced adhesive strength.

Using other lights often results in improper curing and reduced sealant performance. Please use the recommended UV light.

Do not use sunlight. Sunlight is difficult to direct appropriately onto the application area, and even if curing occurs, the film quality is poor and sealing performance cannot be fully achieved.

Shelf life (unopened) is approximately 2 years from manufacturing. However, if more than 2 years have passed, it can still be used if it has not solidified after stirring.

There are cases of large outdoor transformers where no leak recurrence has occurred for several years after application. However, the target service life is 1 year. Sealant durability is greatly affected by the quality of application.
