Product Identity

Henry HE558018 is a silver aluminum roof coating supplied in a five-gallon pail. It is formulated for professional contractors and property owners who need a reflective finish on compatible low-slope roofing assemblies.

Build Integration

The water-based asphalt resin applies at room temperature and covers approximately 100 square feet per gallon on smooth built-up, modified bitumen, prepared asphalt or weathered galvanized metal substrates. It frees the installer from hot-melt equipment and requires only standard brush, roller or spray tools.

Sustained Load Behavior

After a dry time of 2 to 24 hours the matte coating meets ASTM 6848 standards and maintains a low 50 g/L VOC profile. The reflective surface continues to reduce heat absorption over the service life of the roof membrane.

The coating dries in 2 to 24 hours depending on temperature and humidity, so full cure is typically reached within a day.

Will the Henry HE558018 produce strong fumes or heat when applied all day?

VOC content is 50 g/L, so fumes are low and the water-based asphalt resin generates negligible heat during extended application.
