A4431 Dibond adhesive is ideal for bonding aluminium composite material. (ACM).

A4431 is a non-flammable, new generation, two-component structural adhesives. This product represents a new level of performance for 10:1 low shrinkage high elongation structural methacrylate adhesives. A4431 offers a very tough and flexible bond, with high peel, and impact strength, at both low and elevated temperatures. It’s formulated from our innovative and bespoke blend of low-odour, non-flammable and non-carcinogenic monomers.

Once mixed at the 10:1 ratio the working time of the A4431 is the period whereby the adhesive remains fluid and is easily transferrable between two or more mating surfaces. Temperature, volume, and substrate have a direct effect on the length of this period as the A4431 cures by an exothermic reaction. Higher temperatures and larger volumes speed the reaction causing a reduction in open and cure time. Lower temperatures and smaller volumes slow the reaction time extending both the open time and ultimate full cure time.

Applications:

A4431 is very versatile, and can bond a wide variety of substrates without the need for surface primers or conditioners:

• Bonding locators to ACM (dibond) without read-though or witness marks.

• Bonding mild steel frame to FRP and offering high vibration and impact resistance

• Bonding fasteners to GRP and FRP moulded parts.

• Bonding and laminating composite panels.

• Composite and metal fabrication for seating construction.
