Epoxy Bonding Agent Testing

Epoxy Bonding Agent Testing
(Two-Component Epoxy — BS EN 12188)

Mechanical testing of two-component epoxy bonding agents for structural concrete repair — verifying compressive strength, tensile strength, bond strength and open time per BS EN 12188 and EN 1504-4.

Overview

What is the Epoxy Bonding Agent Testing?

Epoxy Bonding Agents are two-component (resin + hardener) epoxy systems applied to concrete substrates before repair mortar or overlay application. They provide a strong chemical bond between new repair material and the existing concrete substrate — critical for structural repair systems specified per EN 1504.

At Global Lab, epoxy bonding agent testing is conducted as per BS EN 12188 covering compressive strength, tensile strength, bond strength to concrete (pull-off), open time (pot life), coefficient of thermal expansion and modulus of elasticity — confirming compliance with EN 1504-4 structural bonding requirements.

Bond Strength to Concrete

Pull-off adhesion on sandblasted concrete substrate per BS EN 1542.

Compressive & Tensile Strength

Neat epoxy mechanical properties per BS EN 12188.

Open Time Verification

Pot life and open time tested for site workability compliance.

EN 1504-4 Compliance

Results checked against EN 1504-4 structural bonding minimum requirements.

NABL Certified Reports

All results on NABL-accredited letterhead per BS EN 12188.

Temperature Range Testing

Bond strength at elevated temperature for tropical site conditions.
