Henkel Technomelt PA 676 Black High Temperature Polyamide Hot Melt Adhesive

Technomelt PA 676 Black for High Temperature Molding Applications

Technomelt PA 676 Black is a high temperature polyamide hot melt adhesive designed for molding applications. It offers strong resistance to elevated heat while maintaining structural stability after cooling. The material applies at high processing temperatures and solidifies by physical setting into a durable thermoplastic bond. Its thermal performance makes it well suited for demanding industrial environments where heat exposure is a key consideration.

Key Benefits of Henkel Technomelt PA 676 Black

• High Temperature Creep Resistance: Delivers sustained performance up to 329°F (165°C), supporting structural stability in heat-intensive molding environments.
• Elevated Softening Point: With a softening range of 383–401°F (195–205°C), the material helps resist deformation under prolonged thermal exposure.
• Optimized for Molding Applications: Polyamide-based formulation designed for controlled melt flow and reliable mold processing.
• Wide Processing Temperature Range: Applies at 410–464°F (210–240°C) to enable consistent flow and mold fill during production.
• Thermoplastic Physical Setting: Cures by physical setting into a durable thermoplastic bond without chemical crosslinking.
