Permabond UV 625 UV Curable Adhesive

PERMABOND® UV625 is a single part, fast curing, UV curable adhesive primarily designed for bonding and sealing glass and metal. The cured adhesive is tough, flexible and has excellent impact resistance. The gel-like viscosity and good depth of cure make it ideal for use on vertical surfaces or where large gaps are involved.

Features

•  Cure on demand
• Non-drip
• Flexible, good impact resistance
• Fast curing with low-power lamps
• 100% solids, no solvents
• Excellent adhesion to metal and glass

Storage & Handling

Storage Temperature

• 5 to 25°C (41 to 77°F)

Allow adhesive to reach room temperature before opening bottle to prevent condensation inside the bottle which can reduce shelf life.

Surface Preparation

Surfaces should be clean, dry and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces. Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.

Directions for Use

1. Apply the adhesive sparingly to one surface.
2. Bring the components together quickly and correctly aligned.
3. Apply sufficient pressure to ensure the adhesive spreads into a thin film.
4. Do not disturb or re-align until sufficient strength is achieved, normally in a few seconds.
5. Any surplus adhesive can be removed with Permabond CA solvent, nitromethane or acetone.

NB: For difficult or porous surfaces using a Permabond activator is recommended. If bonding polypropylene, polyethylene, PTFE or silicone, prime first with Permabond Polyolefin Primer (POP).
