Discover the benefits of Foster 30-36 Canvas Coating – a flexible, durable, and water-resistant coating used to seal and protect insulated canvas jacketing in HVAC and industrial systems.
Foster 30-36 is a high-quality weather-resistant canvas coating designed specifically for use over canvas insulation coverings. It provides a clean, white, flexible finish that protects underlying insulation systems from moisture, UV rays, dirt, and mechanical damage.
This coating is widely used in HVAC, mechanical piping, ductwork insulation, and other industrial applications where durability and appearance are important.
✅ Flexible & Durable Finish
Does not crack or peel with thermal expansion and contraction.
✅ Water-Resistant Barrier
Prevents moisture intrusion into insulation materials.
✅ UV Resistant
Maintains integrity and color when exposed to sunlight.
✅ Mildew & Fungal Protection
Resists biological growth on insulated surfaces.
✅ Easy to Apply
Can be brushed, rolled, or sprayed over canvas surfaces.
Foster 30-36 is commonly used in the following areas:
1. HVAC Systems
Used over canvas-jacketed duct and pipe insulation to protect from wear and external elements.
2. Mechanical Insulation
Provides a sealant and finish over fabric insulation jackets in commercial and industrial facilities.
3. Marine & Offshore
Ideal for protecting insulation in environments with high moisture and corrosion potential.
4. Cold Storage & Refrigeration
Helps prevent vapor drive into insulation systems by forming a strong barrier layer.
Improves System Longevity
Extends the life of insulation by shielding it from damage and moisture.
Clean Aesthetic Finish
Dries white and provides a neat, uniform appearance.
