Marine Polyurethane Spray Foam is a high-performance insulation material designed for marine environments. It provides excellent thermal and moisture resistance, ensuring durability in harsh conditions. The foam expands to fill gaps, creating a seamless, airtight barrier for superior insulation.

Size: Available in aerosol cans (12 oz, 24 oz) or bulk containers (55-gallon drums).

Grade: Closed-cell, high-density foam (typically 2-3 lb/ft³).

Viscosity: Low viscosity before application (200-500 cP), expands rapidly upon spraying.

Buoyancy: High buoyancy (up to 60 lbs/ft³ when cured).

Material: Polyurethane-based (MDI or polyol blend), often with added waterproofing agents.

Expansion Rate: 20-30x original volume (depends on temperature/humidity).

R-Value: ~6.5-7.0 per inch (thermal insulation).

Cure Time: 5-10 minutes tack-free, full cure in 24 hours.

Water Resistance: Hydrophobic (negligible water absorption).

Adhesion: Bonds to wood, fiberglass, metal, and most marine substrates.

Operating Temp: -40°F to +200°F (-40°C to +93°C).

Flammability: Class B fire rating (self-extinguishing).

Marine Polyurethane Spray Foam may comply with maritime standards such as SOLAS, IMO, or specific classification society requirements. Always verify with the manufacturer for exact certifications.
