3M 7000121532 Hybrid Adhesive Sealant 4000 Uv White 400 Ml

Product Description

The 3M 7000121532 is a one-part hybrid adhesive sealant in the Fast Cure 4000 UV formulation, supplied in a 400 mL sausage pack in white. It cures to a firm, flexible, rubbery seal that is fully waterproof and resistant to UV degradation. The cured material absorbs stress from shock, vibration, thermal expansion, and contraction, making it well suited for structural bonding and sealing applications where joint movement is expected. Licensed marine contractors and boat builders are the primary installers, though it also sees use by general contractors on exterior facade and glazing work requiring UV-stable sealant performance.

This sealant is formulated for marine environments and is rated for use both above and below the waterline. Its UV resistance makes it a reliable choice for cosmetic sealing on exposed hull, deck, and topside surfaces where color stability and weather durability are required over the long term. The sausage pack format is compatible with standard bulk sausage dispensing guns, allowing efficient application on larger jobs or production-volume work.

Key Features

• One-part formula — no mixing required, ready to dispense from the sausage pack
• Fast cure rate reduces wait time between application and return-to-service
• Superior UV resistance maintains color and integrity on exposed surfaces
• Waterproof seal rated for above- and below-waterline marine applications
• Flexible cured body dissipates stress from vibration, shock, and thermal movement
• White finish suitable for cosmetic topside and deck sealing work

Compatibility

Designed for marine applications above and below the waterline; suitable for bonding and sealing on boat hulls, decks, and other exterior surfaces where UV-stable, waterproof performance is required.

Installation Notes

Application requires a sausage-style bulk dispensing gun sized for 400 mL cartridges. Surfaces should be clean, dry, and free of oil, wax, and loose material before sealant is applied. Follow the manufacturer application temperature range and allow full cure before submerging or loading the joint. Installers working in confined or below-deck spaces should ensure adequate ventilation during application and cure.
