Dow Corning 3-4000 Silicone Roof Coating is a one-component, moisture-curing silicone rubber roof coating system designed for use on sprayed-in-place polyurethane foam.
It is available in two colors and is applied in two contrasting coats. When properly applied, the cured coating provides a weathertight seal that will protect polyurethane foam from degradation caused by ultraviolet light, water and other normal weathering hazards. |
