Henkel Technomelt PA 652 N UL 94 V-0 Flame Rated Polyamide Hot Melt Adhesive

Technomelt PA 652 N Thermoplastic for Flame-Rated Molding and Cold-Temperature Flexibility

Technomelt PA 652 N is an amber, UL 94 V-0 rated polyamide hot melt adhesive engineered for low pressure molding and encapsulation applications. Its low viscosity supports reduced processing pressure, helping protect fragile electronic components during molding. The material delivers excellent adhesion and outstanding cold-temperature flexibility down to -58°F (-50°C), making it well suited for demanding assemblies. With performance across a -40°F to 212°F (-40°C to 100°C) operating range, it provides dependable protection in challenging environments.
