Product Information Sheet
M600 FireBloc
ModBit Fibered SEBS Aluminum

USES: M600 FireBloc protects surfaces exposed to the sun's destructive ultraviolet (UV) rays. FireBloc increases the service life of roofs, as well as reduces energy costs by lowering inside building temperatures. FireBloc is compatible with SEBS, APP, and SBS modified bitumen asphalts and will adhere to most surfaces including roofing, wood, metal, rubber, plastic, glass, and concrete. FireBloc forms a metallic, reflective shield that protects and beautifies.

DIRECTIONS: New asphalt surfaces shall be allowed to set up a minimum of 90 days prior to applying M600 FireBloc. FireBloc is friendly to apply, especially in cool to moderate temperatures. Clean gravel, dirt, vegetation, and debris from the application area. Seal any leaking penetrations and repair all surface fissures with M300 RubrMastic and PolyWeb. Prime the surface to be coated along with any uncoated masonry and new metal with M400 RubrPrime. Use a thick nap roller, medium stiff bristle brush, or low pressure spray equipment to apply FireBloc directly from the container without diluting. Thoroughly stir FireBloc just prior to application, working the aluminum pigment up from the bottom of the container. Apply FireBloc at the rate of 1.5 gallons per 100 square feet.

DESCRIPTION: M600 FireBloc is a fibered aluminum coating made especially for fire rated modified bitumen roofs. FireBloc has been engineered to provide a Class A Fire Rating over most roofing including SEBS, APP, and SBS roofs. Select raw materials, including 100% oxidized roofing asphalt, have been formulated to make FireBloc a premium aluminum coating. FireBloc is a patented breakthrough achieved by Fields in SEBS chemistry. The SEBS rubber in FireBloc provides maximum elastic performance against thermal shock, the daily expansion and contraction of a roof caused by temperature changes. SEBS rubber polymers are the only ones known to effectively resist the sun's destructive UV rays that attack the roof membrane making it brittle and weak, inducing membrane ruptures during thermal shock cycles. FireBloc is your best defense against these attacks. With FireBloc, your roofing installations will perform much longer. FireBloc is asbestos free.

SEBS RUBBER: The SEBS rubber in M600 FireBloc provides greater flexibility, lower moisture permeability, greater fatigue resistance, better weathering durability, greater tensile strength, higher temperature stability, and improved resistance to UV rays, ozone attacks, and roof oils.

SPECIFICATIONS: M600 FireBloc exceeds the minimum standards of the American Society for Testing and Materials ASTM D 2824 Type 3. Maximum VOC 500 grams per liter.
