Seal-glo Insulating moistureproof coating



Icon of Seal-glo Insulating moistureproof coating

Dries at normal temperature to protect substrates
from moisture and dirt

This is a moisture-proof insulation coating agent that exhibits moisture-proof property and electrical properties despite being a thin film. It can cure without affected by the unevenness of densely mounted electric components. Please use it for conformal coating of substrates and moisture-proof insulation sealing for electric components.


Excels in moisture resistance.

By covering the surface of printed circuit boards and electric components with a film with excellent moisture-proof property, Our coating products protect protects them from moisture, condensation, and similar elements. In addition, it also prevents foreign substances of gas, oil, detergents, mold, and dust from adhering and contributes to the suppression of malfunctions and disconnections of electric devices.



Adopting a resin with excellent insulation, protects the printed circuit boards and electric components, which are the heart of electroc devices, from static electricity. It has excellent track records of adoption in a wide range of fields, such as automobiles and industrial equipment, where safety is considered important.
