Can be used above or below the waterline; approximately half the strength of 3Ms 5200, which allows for eventual dissasembly of parts. Note: Can be softened by some teak cleaners and sealers and is not recommended for sealing teak decks.Key featuresForms watertight, weather-resistant sealsChemically reacts with moisture to deliver flexible bondsCan be used above or below the waterlineCleans up with mineral spirits or keroseneSpecificationsFormulation: One-part fast-cure polyurethane adhesive/sealantRecommended Usage: Fiberglass, wood, metal, some plastics, above or below waterMaterial Incompatibilities: Acrylics, ABS, LexanCure Time: Tack-free: 2hrs.; Complete cure: 24hrs.Cleanup: Mineral spirits or keroseneRemoval: Mechanical removalTensile strength: 300psi
