Two-Component AB Adhesive: Characteristics, Applications and Uses

Two-component AB adhesive is highly valued for its strong bonding performance, resistance and versatility across many materials and industries.

What is two-component AB adhesive? It combines Part A resin with Part B hardener, mixed at the correct ratio before application. The suitable formulation depends on the material and process. See also our epoxy adhesive usage guide and industrial wood adhesive solutions.

Technical characteristics of two-component AB adhesive

Two-component AB adhesive consists of Part A, an Epoxy resin adhesive, and Part B, a curing agent. The two parts must be mixed at the appropriate ratio to form a complete adhesive. It can be used on many material surfaces, including slightly damp surfaces.

• It works both as an adhesive and a protective coating with strong water and mould resistance.
• High adhesion creates a durable bond.
• Good durability under high temperatures, chemicals and harsh weather conditions.
• Good resistance to tensile and tearing forces.
• Resistant to acids, alkalis, salts and fuels.

Popular types of AB adhesive

Manufacturers offer different AB adhesive types to meet diverse application requirements.

Spray-type two-component AB adhesive

AB Epoxy spray adhesive cures in approximately 5–10 seconds, is transparent and provides high adhesion. Its main limitation is the small package size.

Slow-curing two-component AB adhesive

This pre-mixed A/B adhesive takes about 30 minutes to cure and up to 24 hours to fully harden. It becomes transparent during use without yellowing or leaving black marks.

Fast-curing AB Epoxy adhesive

This type is supplied in two separate containers and cures in approximately 20 seconds, while offering a larger volume than spray packaging.

Standard two-component AB adhesive

Standard AB adhesive is transparent and supplied in larger packages. It takes about 20 minutes to cure and approximately 2 hours to fully harden.

TECHBOND supplies various AB adhesive types and can flexibly customise technical specifications for each application, process and machine. Solutions can be adjusted for adhesion, viscosity, curing time and appearance requirements.
