LOCTITE® HHD 8000R™ (also known as HF8000R™) is a two-component methacrylate adhesive that cures at room temperature. It is supplied as a yellow resin (Part A) and a blue hardener (Part B), which mix in a 10:1 volume ratio to form a green adhesive. The system is non-sagging, enabling easy application on vertical or overhead surfaces. It delivers fast fixture, excellent bond strength on metals and composites, high elongation, and outstanding cold-temperature impact resistance. The cured adhesive forms resilient, durable joints across a broad temperature range.
Structural bonding of metals, composites, plastics, and magnets.
High-strength joining in industrial assemblies requiring durability under impact and thermal cycling.
Substrates such as aluminum, steel, glass, acrylic, phenolic, ABS, PVC, polycarbonate, ferrite magnets, FRP, magnesium, and PC/ABS blends.
