Product Description
Bostik Born2Bond™ HHD 5518BK is a one-component, solvent-free, moisture-curing polyurethane adhesive. Upon dispensing, the adhesive reacts with ambient moisture or the water content of substrates, forming a cross-linked thermoset structure. This high-performance adhesive also contains a fluorescent agent, enabling UV inspection for precise quality control. HHD 5518BK is designed for structural bonding applications, offering superior strength and durability for various substrates.
Key Features of HHD 5518BK
- Excellent Adhesion – Bonds effectively with a variety of substrates, including glass, metal, and more.
- High Initial Strength – Ensures quick and reliable bonding, making it ideal for structural applications.
- Long Open Time – Provides ample time for adjustments and positioning before the adhesive sets.
- Good Aging Resistance – Maintains bond integrity over time, even under demanding conditions.
- Precision Dispensing – Allows for accurate, controlled application, ensuring uniform bonding.
- UV Inspection Capability – Contains fluorescent agent for easy visual inspection under UV light.
