ARALDITE® AW 2101 / HARDENER HW 2951 is a rapid-curing, two-component epoxy paste adhesive designed for high-strength, tough, and durable bonding. It cures at room temperature with low shrinkage and provides excellent resistance to oils, petrol, and mechanical stress. The adhesive is lightly thixotropic, non-sagging, and suitable for fast assembly where quick handling strength is required. It bonds an exceptionally wide range of materials, making it a versatile choice for industrial, automotive, electrical, and composite applications.
Bonding metals, ceramics, glass, rigid plastics, composites, CFRP, SMC, rubber, and steel
Gap filling and multipurpose structural assembly
Automotive body/aftermarket repair and general industrial assembly
PCB and electronics bonding
Silicon block bonding to workpiece holders
