ROOFDX SL™ is a siliconmodified, aliphatic polyurethane coating that is tough, flexible, and longlasting. ROOFDX SL has the appearance of lead coated copper but does not contain any lead. ROOFDX SL™ is used as a finish coat over Andek products such as POLAROOF NW, POLAROOF RAC, and ROOFDX SUPER, and it may be used over ROOFDX COPPER in situations where the most similarity to lead coated copper is required. ROOFDX SL is a dense complex barrier coating that combines a unique mineral, micaceous iron oxide, with a blend of flaked metals, including stainless steel, to protect against weathering, corrosion, and chemical degradation. ROOFDX SL's surface develops a silicon hammer finish that is extremely damage resistant and dirt resistant.

Outstanding Features
  • Has the appearance of lead but contains no lead
  • Provides a waterproof, durable, protective finish
  • Retains its lead‐like appearance and ages without discoloration
  • Cures rapidly to form a flexible, tough and abrasion‐resistant coating
  • Resists impact damage without chipping or flaking
  • Low energy surface helps pre‐ vent accumulation of tree resin and bird excrements
  • Highly resistant to staining and deterioration from most chemi‐ cal
  • Retains its dimensional integrity from cold through to hot tem‐ peratures
  • Resists staining and deteriora‐ tion from most chemicals
  • Used as a finish coat over ROOFDX COPPER, it gives the appearance of lead coated cop‐ per for a fraction of the cost.

CAUTION!  Read this entire data sheet before continuing. All surfaces to be coated must be clean, dry and completely free of loose particles, oil, grease, or any substance that would interfere with proper adhesion.  ROOFDX SL may be applied over the products listed in the Description section at any time after they have set or cured thoroughly.  It is important to test for “through‐cure” as coat‐ ing over a dry‐to‐the‐touch surface may cause blisters in the basecoat through solvent entrapment.  Once “through‐cure” has been estab‐ lished by subjecting aggressive torque to the surface, application of the ROOFDX SL may commence.   Add Part ‘B’ color concentrate into Part ‘A’ resin side and stir thor‐ oughly for 3 minutes.  ROOFDX SL is applied at a rate of 400 square feet per gallon in a single coat at a film thickness of 4 mils w.f.t.  ROOFDX SL may be applied by brush, roller or airless spray technique in a thin even coat.  As with any metallic coating, all brush strokes, roller or spray passes should be in the same direction so that the metal flakes within the coating orient them‐ selves evenly for optical uniformity.   Another important procedure is to stir frequently all mixed material to prevent settling of the metal flake pigments.  Do not allow the mixed material to be contaminated with water; otherwise foam, bubbles and pinholes in the coating will develop.  If this does happen, these defects may be sanded out and touched up once the coating has set thoroughly.  Equipment may be cleaned with toluene or xylene while the coating is still wet.

Maintenance

To repair damaged areas, sand thoroughly and remove all dust and dirt with solvent washing.  ROOFDX SL may then be re‐applied to the clean dry surface.
