Fire retardant epoxy adhesives will suit the aerospace sector

Two white IFR structural epoxy adhesive systems have been announced by ITW Devcon. One system offers a five minute working time with a fast cure time of one hour.

The other is a 10 minute non-sagging version which cures in three hours and is ideally suited for use on vertical and overhead surfaces. These two-part self-extinguishing products are available in cartridges, are easy to mix and can be applied using a dispensing gun.

A key environmental benefit is the fact that less smoke is created if the material burns and no halogenated flame retardant additives are used in the formulations and these approvals make the adhesives ideally suited to the needs of the aerospace sector. Additional benefits including fast cure, noise and vibration dampening, low coefficient of thermal expansion, lightweight but strong and flexible long-lasting bonds, high corrosion and fatigue resistance, good impact and peel strengths.

The adhesives are intended for bonding metals, fabrics, ceramics, wood, vinyls and concrete for use in the aerospace, marine, electricity generation and rail industries. Typical applications are expected to be potting inserts, edge sealing of aircraft interiors, and applications where a self-extinguishing structural epoxy system is required.
