HPR25A Structural Adhesive Part A

HPR25A is Part A of the HPR25 two-part structural adhesive system, developed specifically for the structural bonding of aluminium alloys and composite structures. When mixed with HPR25B hardener, it produces a room-temperature curing bond with exceptional strength and outstanding peel resistance.

• High-strength structural bond — exceeds ASTM D1002 requirements
• Exceptional peel resistance for composite and aluminium bonding
• Room-temperature cure — no oven or press required
• Suitable for military, aerospace, marine, and industrial composite applications
• Use with HPR25B (Black or White) or HPR25BLV (Low Viscosity Clear) hardener
• Available in 1KG and 4KG sizes

Mix ratio and pot life data available in the HPR25 technical data sheet.
