DIATHON DP is a unique 100% acrylic elastomer coating which combines high tensile emulsion polymers, reinforcing laminar pigments and non-migrating fire retardants for superior physical properties, durability, weatherproofing, dirt and mildew resistance, ultraviolet resistance and fire retardancy. The fire retardant chemicals are permanently locked into the cured coating and will not leach out upon extended weathering. DIATHON DP is a “breathing?coating, allowing moisture vapor to pass through the film while remaining impervious to mass water penetration. DIATHON DP, when installed by a Certified Contractor, in conjunction with an approved polyurethane foam, qualifies for the Rohm & Haas DURAplus?Roofing System Program. As such, qualifying jobs will be eligible to receive a 10-year limited warranty, covering labor and materials, backed by the Rohm & Haas Company.
DIATHON DP was specifically developed as a superior coating for protecting sprayed-in-place
polyurethane foam insulation from degradation caused by normal weathering, aging and ultraviolet exposure. DIATHON DP has the ability to uniformly cover the profile of textured substrates. Its dense, tight finish repels dirt and pollutants while the elastomeric membrane remains permanently flexible. DIATHON DP can be used for protecting sprayed-in-place polyurethane foam on new or existing roofs as well as heated or ambient storage tanks. It also achieves excellent adhesion over concrete, masonry, primed metal, primed wood and asphaltic surfaces. |
