Diathon^® Roof Coating

Why United Coatings™ Diathon® Roof Coating?

United Coatings™ Diathon® Roof Coating protects from degradation caused by normal weathering, aging, and ultraviolet exposure. It combines high solids emulsion polymers and potent biocides while non-migrating fire-retardant chemicals are permanently locked into the cured coating to ensure performance.

Benefits

Unique among acrylic elastomers in that elongation and tensile strength properties are both maintained at lower temperatures.
Tested and certified to exceed ASTM D6083 standards.
ENERGY STAR® certified (U.S. only).
High acrylic resin content helps provide long-term durability.
Fire retardants are dispersed into the raw material for long-term fire protection.
Protects against normal abrasive weather conditions such as ice, snow, and sand.

Uses

United Coatings™ Diathon® Roof Coating was specifically developed for use over SPF insulated concrete, metal, plywood, and ambient and hot tanks.
