Marine epoxy resin dispensers are specialized tools designed for precise mixing and application of epoxy adhesives in marine environments. These systems ensure accurate resin-to-hardener ratios, crucial for strong, durable bonds in boat building and repairs. They are built to withstand harsh conditions, providing reliable performance for marine applications.

Size: Typically available in 300ml, 600ml, and 1-liter cartridges or dual-cartridge systems.

Grade: Marine-grade epoxy, suitable for underwater and high-moisture environments.

Viscosity: Ranges from 500 to 5,000 cP (varies by formulation).

Buoyancy: Neutral to slightly positive buoyancy when cured, depending on filler content.

Material: Base resin (bisphenol-A or bisphenol-F) with amine or polyamide hardeners.

Cure Time: 5 minutes to 24 hours (depends on temperature and formulation).

Operating Temperature: -40°C to 120°C (-40°F to 250°F) post-cure.

Mix Ratio: Common ratios include 1:1, 2:1, or 4:1 (resin to hardener).

Shear Strength: 15-30 MPa (2,175-4,350 psi) depending on formulation.

Water Resistance: Fully waterproof with excellent hydrolytic stability.

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

Density: 1.1-1.3 g/cm³ (varies with fillers and additives).

Shore Hardness: 70-85 D (after full cure).

Adhesion Strength: 10-25 MPa (1,450-3,625 psi) on steel, aluminum, and composites.

Pot Life: 5-60 minutes (depends on formulation and ambient temperature).

Color: Typically clear, tan, or gray (custom colors available).

Certifications: Meets ASTM C881, ISO 9001, and MIL-SPEC standards.
