Foster® Sealfas® 30-36 HF™ Coating
1 of 78 products in this brandFoster® Sealfas® 30-36 HF™ Coating is a halogen-free, white, fire-resistant indoor coating designed for thermal insulation. It also functions as an adhesive for canvas and glass-lagging cloth. With excellent brushing characteristics, it ensures better coverage and uniformly coated surfaces. This coating maintains a neat white finish and does not yellow or discolor with age. The surface can be easily cleaned to remove grease, oil, soot, and other dirt accumulation.

Applications & Uses
- Cleaning Information
-
Use clean, fresh water for cleaning brushes and equipment before product dries. Dry product may be removed with hot, soapy water or strong solvents such as chlorinated solvent (non-flammable) or mineral spirits (flammable).
- Preparation and Application Information
-
Material Preparation
- Do not thin.
- Apply only to clean, dry, oil-free surfaces.
- Keep container closed when not in use.
Application
- Apply a tack coat at 60 – 70 sq. ft. per gal. (1.5 – 1.7 m2 /l).
- Immediately embed the selected lagging fabric into the wet coating. Smooth to avoid wrinkles and overlap seams by at least 2 inches (5 cm).
- Immediately apply a finish coat at 60 – 70 sq. ft. per gal. (1.5 – 1.7 m2 /l). The dry film thickness of this application will vary with the fabric selected.
- For air conditioning ducts, increase the coverage rate to 40 – 50 sq. ft. per gal. (1.0 – 1.2 m2 /l) for each coat.
Brush
- Use clean paint brushes (suitable for water-based paints).
- Apply with full brush and spread out evenly.
Spray
- Sealfas® Coating may be airless spray applied.
- Average viscosity range: 70,000 – 90,000 cps.
- Corrosion resistant pumps and fittings are suggested.
- At a minimum we suggest the following airless spray equipment or suitable alternative package:
- Pump Graco Checkmate pump, 40:1 on 100cc lower, NXT2200 motor mounted on ram plate, Graco S20C – 5 gallon cart mounted ram
- Fluid Hose High pressure capable of 4,000 PSI. 1⁄2” inch up to 50 feet. 3/4 inch over 50 feet. Use 8’ x 1/2” I.D. hose for coupling to the gun. A higher ratio pump set-up will allow for longer hose runs up to 150’
- Gun Graco mastic or textured coating spray guns with Tip Sizes 521 to 527 Reverse-A-Clean tips
- There are many configurations of airless spray equipment that may be used and we suggest contacting an airless spray equipment supplier to put together a complete package Most manufacturers of mastic spray equipment maintain nearby service facilities to aid in the selection and any technical problems that arise with their equipment.
- Electric airless spray units such as a Graco Ultramax 795 or 1095 sprayer may also be used, however, due to the body of the coating they may not be capable of completely emptying a pail while spraying.
- A minimum volume in the pail may need to be maintained.
Top Coating
- If it is to be top coated with anything other than an alkyd enamel conforming to DOD-E-24607 as specified in MIL-DTL-3316D, the user must confirm by his/her own tests that the products are compatible and that the final results are satisfactory.

- Product Highlights
-
- Sealfas® 30-36 HF™ Coating provides a protective finish for insulation on air conditioning ducts and cold water piping when applied in 2 coats with reinforcing fabric embedded between coats.
- When relative humidity exceeds 75% for continuous periods, or where the insulated piping or equipment contains chilled water, brine or refrigerant, additional vapor barrier protection is suggested.
- Sealfas® 30-36 HF™ Coating is compatible with polystyrene and polyurethane foam insulations.
- It may be applied to the joint or edges of fibrous duct liner insulations to seal and prevent air erosion.
- Sealfas® 30-36 HF™ Coating meets the requirements of Military Specification MIL-DTL-3316D Class 1, Grade A and is listed on the QPD.
- Sealfas® 30-36 HF™ Coating is approved by the U.S. Coast Guard under 164.112/172/0 (SOLAS/IMO approval) superseding 164.012.
- Sealfas® 30-36 HF™ 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
- Sealfas® 30-36 HF™ Coating meets NFPA 90A and 90B 25/50 requirements.
