Foster® 30-36MA Sealfas® Coating (Marine Grade)
FOSTER ® SEALFAS ® COATING Marine Grade (MA)
Foster ® 30-36MA Coating is a white, fire resistive, tough, washable, abrasion-resistant indoor coating specially formulated for marine applications with thermal insulation. It is also used as a lagging and lap adhesive for canvas and glass lagging cloth. It has excellent brushing characteristics, which will result in better coverage, and more uniformly coated surfaces. It presents a neat white finish, and will not yellow or become discolored with age. The surface can be washed free of grease, oil, soot, and other dirt accumulation.
30-36MA 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.
30-36MA 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.
30-36MA Coating meets the requirements of Military Specification MIL-A-3316C Class 1, Grade A and is listed on the QPL.
30-36MA Coating is approved by the U.S. Coast Guard under 164.112/73/1 (SOLAS/IMO approval) superseding 164.012.
30-36MA Coating meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 15 g/l, less water and exempt solvents.
30-36MA Coating meets NFPA 90A and 90B 25/50 requirements.
30-36MA Coating contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. Always test foil and paper facings for acceptable adhesion before using.

DRYING TIME 73ºF (23ºC) 50% RH (ASTM D 1640):
Set to Touch: 2 Hours
Dry Through: 15 Hours
SERVICE TEMPERATURE LIMITS (FSTM 70):
(Temperature at coated surface) 0ºF to 180ºF (-18ºC to 82ºC)
WATER VAPOR PERMEANCE (ASTM F 1249):
1.3 perms at 0.031 in. dry film thickness, (0.9 metric perms at 0.8 mm)
WET FLAMMABILITY (ASTM D 3278):
No flash to boiling, 212ºF (100ºC)
SURFACE BURNING CHARACTERISTICS (ASTM E 84):
Flame Spread: 0
