Foster 30-36 Sealfas® Coating – Fire-Resistive,
Washable, and Durable Insulation Coating

Foster 30-36 Sealfas® Coating is a high-performance, fire-resistive, and abrasion-resistant white coating
designed to provide superior protection for thermal insulation in indoor applications. Engineered for air
conditioning ducts, cold water piping, and fibrous duct liners, this tough and washable coating ensures
long-lasting durability while preventing air erosion, moisture infiltration, and surface damage.

When applied in two coats with reinforcing fabric embedded between layers, Sealfas Coating delivers
exceptional insulation protection, enhancing the longevity and efficiency of HVAC systems. It is compatible
with polystyrene and polyurethane foam insulations and is ideal for commercial, industrial, and institutional
applications where reliable insulation protection is required.

Key Features & Benefits

✅ Fire-Resistive Protection – Specially formulated to enhance fire safety, providing
a flame-retardant barrier for insulation.

✅ Tough & Abrasion-Resistant – Withstands wear and tear, making it ideal for high-traffic
and demanding environments.

✅ Washable & Easy to Maintain – A smooth, cleanable surface ensures long-term performance
without degradation.

✅ Prevents Air Erosion & Moisture Damage – Seals fibrous duct liner joints and insulation
edges, minimizing air leakage and moisture infiltration.

✅ Superior Adhesion & Flexibility – Bonds effectively with polystyrene, polyurethane foam,
and fibrous insulations, ensuring a secure, long-lasting application.

✅ Ideal for HVAC & Chilled Water Systems – Perfect for air conditioning ducts,
cold water piping, and refrigerated equipment, providing enhanced insulation integrity.

✅ Additional Vapor Barrier Recommended – For environments with high humidity (above 75%)
or chilled water, brine, or refrigerant systems, an extra vapor barrier is suggested for optimal performance.
