Product Description
3M™ Polyurethane Adhesive Sealant Fast Cure 550 is a fast-curing, one-component, moisture-curing polyurethane sealant that forms permanently elastic bonds. It is designed to bond a wide variety of dissimilar materials including plastics, metals, fiberglass, and wood, offering high tensile strength suitable for fastener replacement. This versatile adhesive sealant features a high modulus and Shore A hardness for robust bonding, and it is paintable after curing to improve the final product finish.
Key features
- Fast-curing, one-component formula: Moisture-curing system requires no mixing, simplifying production and assembly processes.
- Permanently elastic and strong: Features high tensile strength for potential fastener replacement and a high modulus for stronger, durable bonds.
- Excellent substrate versatility: Readily bonds dissimilar materials like plastics, metals, fiberglass, and wood to provide design flexibility.
Applications / Suitable for
- General industrial, construction, marine, and specialty vehicle bonding
- Marine deck to hull bonding
- Sealing and bonding diverse, dissimilar materials
