Marine Polyurethane Sealant is a waterproof, flexible adhesive designed for marine environments. It provides strong bonding and sealing for boats, docks, and other watercraft applications. Resistant to saltwater, UV rays, and harsh weather conditions.

Size: Available in standard 300ml cartridges and 600ml sausages.

Grade: High-performance, waterproof, and UV-resistant.

Viscosity: Thixotropic paste, approximately 200,000-300,000 cP.

Buoyancy: Non-buoyant, designed for underwater and marine applications.

Material: Polyurethane-based, with added polymers for flexibility and adhesion.

Cure Time: 24-48 hours for full cure, depending on temperature and humidity.

Shore Hardness: ~30A after curing.

Elongation: Up to 400% for superior flexibility.

Temperature Resistance: -40°C to +90°C.

Adhesion Strength: ≥2.5 MPa on various substrates (metal, fiberglass, wood).

Chemical Resistance: Resistant to saltwater, oils, and mild acids.

Application Method: Gun-applied or trowel-applied, depending on consistency.

Marine Polyurethane Sealant and Marine Adhesives typically comply with maritime standards such as ISO 9001, ASTM C920, or MIL-S-23586, depending on the specific product and manufacturer. Always check the product datasheet or certification for exact compliance details.
