Rust prevention cap <Zinc Hat> *Performance verification test materials provided

We would like to introduce the performance verification results of the anti-corrosion protective cap "Zinc Hat."

We would like to introduce the results of the performance confirmation test for the anti-corrosion protective cap "Zinc Hat." The "Zinc Hat" is a cap designed for the anti-corrosion protection of bolts and nuts used in sound barriers along elevated highways, amusement park equipment, solar panels, and more. In the performance confirmation test of the Zinc Hat under outdoor exposure, it was found that while the steel materials and anchor bolts without protection showed severe corrosion across their surfaces, the anchor bolts covered with the Zinc Hat maintained their initial condition without any corrosion, thanks to the sacrificial corrosion effect of zinc, despite a three-year exposure period. [Test Types] ■ Performance confirmation test under outdoor exposure ■ Immersion test using tap water ■ Comparative confirmation test with resin caps For more details, please refer to the catalog or feel free to contact us.
