HydroArmor® 7763
1 of 4 products in this brandHydroArmor® 7763 is a sprayable latex coating designed for use on aluminum, fiberglass, cold-rolled steel, galvanized steel, and most metal primers. It is formulated with additives to improve adhesion to oily metals. It provides very good corrosion protection, even when applied as thinly as 10 mils wet. This low-viscosity, sag-resistant coating can be easily sprayed onto exposed underbody areas and into restricted areas such as tubing and "hidden" areas accessible only with spray wands. Wet film builds of up to 20 mils can be applied without runs, drips, or sags.

Applications & Uses
- Application
-
- As with any coating, all loose dirt and rust should be removed before application.
- HydroArmor® 7763 is designed to be applied with airless spray equipment. We recommend that a minimum of 10 wet mils of HydroArmor® be applied for optimum performance. We have sprayed this product with a 30:1 airless pump with a Graco airless spray gun. With this equipment, we can spray at 40 to 50 pounds air pressure using spray tips with orifices from 0.015” to 0.027”.
- HydroArmor® resists water wash-off after air drying 30 minutes at 45% - 55% relative humidity. If not baked, it dries through in 24 hours or less (drying is slowed by high humidity and poor air circulation).
- Until HydroArmor® dries, overspray can be removed and equipment can be cleaned with water. Dried material can be removed with methyl ethyl ketone.

Features & Benefits
- Product Highlights
-
- Our tests of HydroArmor® 7763 show this coating is extremely durable under even the worst service conditions:
- Several days at 121°C (250°F) and immersion in acidic and caustic solutions did not affect the dried film.
- Rocks bounced off the coating when test panels were subjected to the “Gravelometer” at -34°C (-30°F).
- After 1500 hours in the salt spray cabinet, the HydroArmor® coating remains intact and there is no corrosion under the coating.
- HydroArmor® dries quickly at ambient temperatures and will withstand urethane paint bakes after only 30 minutes dry time at room temperature.
- HydroArmor® is as safe to use and as easy to clean up as latex house paint.
- HydroArmor® 7763 provides better protection than any of the competitive products we’ve tested without environmental and safety problems inherent in many of the undercoatings available today.
- Easily sprayed onto overhead and vertical surfaces to seal joints
