Marine leak sealants and repair kits are specialized products designed to quickly fix leaks in boats and marine vessels. These kits typically include waterproof adhesives, patches, and compounds that bond to wet surfaces. They provide temporary or permanent solutions for hull, pipe, and other underwater repairs.

Size: Available in tubes (50ml to 300ml), cartridges (300ml to 500ml), or bulk containers (1L to 5L).
Grade: Classified by ASTM C920 or MIL-S-45180 standards, with varying grades for flexibility and adhesion.
Viscosity: Ranges from 5,000 to 50,000 cP (centipoise), depending on application (thixotropic for vertical use).
Buoyancy: Neutral to slightly positive buoyancy when cured (specific gravity 0.95–1.1).
Material: Polyurethane, polysulfide, or epoxy-based formulations; may include fiberglass or metal reinforcement in repair kits.
Cure Time: 5 minutes (fast-set) to 24 hours (full cure), depending on product and temperature.
Temperature Resistance: -40°F to +250°F (-40°C to +120°C) for most formulations.
Adhesion: Bonds to fiberglass, wood, metal, and plastics with tensile strength of 200–800 psi.
Elongation: 200%–600% for flexible sealants.
Waterproof: Fully waterproof upon curing, resistant to saltwater and UV exposure.
