HPR25B Black is the Part B hardener of the HPR25 two-part structural adhesive system. When combined with HPR25A resin, it produces a room-temperature curing bond with exceptional strength and peel resistance — ideal for structural bonding of aluminium alloys and composite structures where a dark or concealed bond line is preferred.
Black pigmented hardener — produces a dark, concealed bond line
High peel and shear strength — exceeds ASTM D1002
Room-temperature cure with no press or oven required
Suitable for composite, aluminium, marine, and industrial bonding
Use with HPR25A resin at specified mix ratio
Available in 250G, 1KG, and 5KG sizes
Refer to the HPR25 technical data sheet for mix ratios, pot life, and cure schedule.
