ET5428 Fast Composites Structural Epoxy Adhesive (Off White) 50ml

ET5428-B from Permabond is one of the highest performing two-part structural epoxy adhesives on the market for the bonding of composite materials, in particular carbon fibre, to each other and to other substrates including metals such as aluminium, titanium and steel.

In our own independent testing, ET5428 outperformed 3M’s highly regarded DP490 and our own VM100 MMA adhesives for carbon-to-carbon and carbon-to-aluminium bonding. Additionally, the toughened formula offers exceptional resistance to impact and vibration. As such, ET5428 and its slower ET5429 variant are the adhesives we recommend for applications requiring the highest possible bond strength and toughness for composite assemblies.

The adhesive is relatively thixotropic, allowing it to accommodate gap-filling up to 5mm and application on vertical surfaces without slumping.

ET5428-W has good temperature resistance - still retaining 50% of its maximum strength at 105°C, as well as resistance to fuel and other chemicals.

Colour

This listing is for the natural off-white/cream colour version of ET5428, recommended for a discreet bond-line when bonding fibreglass/FRP/GRP and other light-coloured materials. A black version ET5428-Black is also available, recommended for bonding carbon fibre and other dark materials.

Main Characteristics

Pack Sizes and Dispensing

ET5428-W is available in 50ml or 400ml pack sizes which can be selected at the top of the page. Both pack sizes use 2:1 ratio cartridges and require a suitable cartridge dispenser gun.

• 50ml packs require our standard 50ml Adhesive Dispenser Gun which is suitable for 1:1 and 2:1 adhesive cartridges
• 400ml packs require a 400ml 2:1 Adhesive Dispenser Gun

The cartridges are intended to be used with static mixer nozzles which fully mix the two components as they pass through the nozzle. They are supplied with one nozzle but once used, adhesive cures in the nozzle and they need to be discarded. Additional nozzles are available to buy separately:

• 50ml packs require a Type 2 Static Mixer Nozzle for 50ml Cartridge
• 400ml packs require a Type 2 Static Mizer Nozzle for 400ml Cartridge
