| Generic Type |
Aromatic Urethane, Zinc-Rich |
| Common Usage |
An advanced technology, two-component, moisture-cured, zinc-rich primer providing extraordinary performance. It’s user friendly and rapid curing so chemical- and corrosion-resistant topcoats can be applied the “same-day.” Also used for field touch-up of inorganic zinc coating. Application methods, for 90-97 only, include “dry-fall” under certain conditions (see Application). H90-97 is HAPS compliant for use in-shop. |
