Ultrathin Coating


PROMOSOLV™ COAT UT10 2%, formulated by Inventec, is a hydrophobic and oleophobic thin-film coating suitable for protecting electronic boards from moisture, chemicals and dust. It adheres well to a wide variety of materials such as plastic, glass, metal and ceramic.

The coating is available with solid content of 2, 4, and 8 percent, which provides different dry film thickness.

When an immersion process is used, the 8% version is used to supplement the solid content in the coating bath in an immersion process.
