Read Material Safety Data Sheets before using this product. 298AF Alumin-R DESCRIPTION: Karnak #298AF Alumin-R is a single component, SBS rubber modified asphalt, and is specially formulated with aluminum pigment to be used as a reflective elastomeric coating with modified bitumen membranes, B.U.R., properly sloped residential concrete roofs and primed metal surfaces. The strength and elastomeric qualities of Karnak #298AF Alumin-R combined with its reflective properties, enhance the coating’s ability to resist movement. Karnak #298AF Alumin-R provides the membrane with good weathering and elongation properties and reduces roof surface temperatures. ADVANTAGES: 1. Easy to apply. 2. 24 hour cure. 3. Tough, flexible elastic, rubber-like film. 4. Excellent adhesion over clean asphalt surfaces. 5. Excellent water and water vapor resistance. 6. Excellent weather resistance. 7. Good resistance to salts and alkalies. 8. Aluminum reflectant characteristics. USES: Karnak #298AF Alumin-R is recommended as a coating for on modified bitumen membranes, BUR, metal and mobile home roofs. SURFACE PREPARATION: All surfaces to be coated with Karnak #298AF Alumin-R must be clean, dry, free from oil, grease, and loose debris. New asphalt roof surfaces may be coated with Karnak #298AF Alumin-R five days after their installation. Modified bitumen membranes should be coated immediately after the membrane has been laid into place. Metal roofs should be brushed or sandblasted with a pressure washer to remove rust and loose flaking prior to the application of Karnak #298AF Alumin-R. Karnak #298AF Alumin-R should be mechanically mixed for several minutes before application. Badly weathered or alligatored asphalt surfaces should be primed with Karnak 100AF Non-Fibered Emulsion or 220AF Fibered Emulsion prior to coating with 298AF Alumin-R. Allow emulsion primer to cure a minimum of 3-5 days before application of aluminum coating. 330 CENTRAL AVENUE, CLARK, NJ 07066 732-388-0300 • 800-526-4236 • FAX: 732-388-9422 WEB: http://www.karnakcorp.com
