Foster® Eclipse™ Coating 40-11

• ECLIPSE™ COATING dries to form an effective air erosion preventive surfacing material sealing and reinforcing the surface of new or aged duct liner insulation materials.
• ECLIPSE™ COATING is non-flammable when wet and extremely fire-resistive when dry.
• When tested on both faced and unfaced fiberglass duct liner insulation, it produced flame and smoke ratings below the 25/50 NFPA 90A and 90B requirements.
• The dry film stays flexible and moisture resistant.
• It will not cause flash rusting on metal surfaces.
• When dry, Eclipse™ Coating resists mold, fungus, discoloration from mildew and stains by mold.
• Its extremely high level of resistance enhances the longevity of the material.
• ECLIPSE™ COATING meets NFPA 90A and 90B 25/50 requirements.
• FOSTER® ECLIPSE™ COATING 40-11 meets the requirements of:
  • MAS Certified Green®
  • California Dept. of Public Health Standard Method v1.2
  • VOC Emissions and Content requirements to contribute to LEED v4 EQ Credit: Low Emitting Materials – Paints and Coatings
  • Collaborative for High Performance Schools EQ 7.1

• Apply between 50°F (10°C) and 100°F (38°C) with less than 70% RH air conditions maintained until dry.
• Water-based products may corrode carbon steel spray equipment.
• Corrosion resistant pumps and fittings are suggested.
• For interior use only.
• Do Not Dilute.

Material Preparation

• Do Not Thin.
• Apply only to clean, dry surfaces.
• Keep container closed when not in use.

Surface Preparation 

• Lined air ducts should be thoroughly cleaned to remove all mold, dust and loose particles, being careful not to tear or loosen the liner.
• Galvanized surfaces need to be vacuumed or washed clean of all accumulated mold, dust and loose particles.
• Following complete cleaning procedures, sanitize the entire air duct surfaces with an approved sanitizer following manufacturer’s directions.
• Ensure that all interior surfaces are thoroughly dry before applying Eclipse™ Coating (40-11).
• All rusted metal surfaces must be primed before application of Eclipse™ Coating.
• It may be applied directly onto cleaned, unrusted, galvanized surfaces.

Application

• Always ensure adequate ventilation by using negative air pressure in the HVAC system during application.
• Apply Eclipse™ Coating to all surfaces by brush or airless spray at the required rate (see front page).
• Brushing will require two coats applied at 90° to each other.
• Under normal circumstances, a spray application can be completed in one coat, but for extremely porous or irregular surfaces, a second coat may be required.
• Eclipse™ Coating has been designed with an average viscosity range of between 4,000 and 6,000 cps, enabling application by virtually any type of electric airless spray equipment.
• Ensure that the finished surface is smooth and well- sealed.

Note

• Continue to circulate fresh air throughout the system during the application and for as long after the application as is possible.
• Circulated air should be exhausted outside the building.
• If air must be exhausted inside the building, filtration through a charcoal medium is suggested.
• This circulation and filtration helps to reduce the dry time of the coating and reduce latex-type odors that could possibly migrate from the application area.
• Be sure exhausted air is odorless before venting into occupied spaces.

Maintenance

• Normal cleaning procedures must be maintained in HVAC systems to remove accumulated airborne particles.

• Use fresh water to clean brushes before product dries.
• While the product is still wet, flush the equipment with a solution comprised of 1/2 cup sudsy ammonia, 1/2 cup pine oil cleanser, and 4 gallons of cool water.
• Flush until material exiting pump shows no evidence of Eclipse™Coating.
• Dry product may be removed with chlorinated solvents (non-flammable) or xylol (flammable).

¹ - Tested at coverage rate of 150 sq. ft./gal. (3.68 m2 /l). Applied to 1" (25 mm) faced duct liner. The flame spread may vary at different product thicknesses and/or when applied over other surfaces.

² - Subject to the nature of material being coated. Wet coverages shown below are for smooth, non-eroded surfaces. Eroded, rough or low density surfaces may require higher gallonage to attain required surface sealing.

0.011 to 0.032 in. wet thickness (0.27 to 0.81 mm)

• Store between 40°F (4°C) and 100°F (38°C).
• Protect from freezing until dry.
