Araldite EP1000AB has good mechanical properties

A Huntsman Advanced Materials product story

Edited by the Engineeringtalk editorial team Mar 25, 2009

Huntsman Advanced Materials has announced the launch of Araldite EP1000AB, a nano-toughened epoxy paste adhesive.

for aircraft specification requirements at low, ambient and relatively high temperatures.

Specific, dispersed organic nanoparticles are incorporated into an epoxy system to give the adhesive good toughening features.

The average particle size is submicron, inhibiting micro-crack propagation while leaving the continuous cured epoxy matrix able to perform at relatively high temperatures.

A catalyst means that an autoclave should not be required.

Curing takes place at moderate conditions well below 100C and storage is at ambient temperatures for at least six months.

Araldite EP1000AB is part of a group of nanotechnology toughened epoxy resins, whose mechanical performance characteristics together with their ease of application and storage features make them good candidates for other applications such as the bonding and repair of windblades.

AralditeEP1000AB is available for sampling.

Araldite Digitalis is able to manufacture large numbers of parts simultaneously with previously unattainable accuracy.

Araldite Digitalis is based on micro-electro mechanical systems (MEMS) and it is easy to use and maintain.

Araldite Digitalis is also different from the light-reflecting MEMS technology used in 3D printers.

At the heart of Araldite Digitalis is the MLS Microlightswitch, an exposure system operating via a computer-controlled micro-mechanical shutter system, which enables a large surface area of radiation-curable resin to be selectively exposed in a single step.

There is fast uniform exposure with high accuracy.

The benefits offered by the new technology grow as the number, size and complexity of parts produced increases.

Araldite Highly Flexible Composite has similar material characteristics to elastomers - good impact-, abrasion- and tear-resistance - with good elongation and tensile resistance, and is different in terms of material and production time costs.

It has the potential to break into a range of different markets, particularly where safety is of paramount importance.

With Araldite Highly Flexible Composite only a few consumable materials are needed - resin and fibre - and, most importantly, a single shell mould is required for component production.

As opposed to elastomers, where it is difficult to incorporate fabric reinforcement and the processing is complex and expensive, the processing of low-viscosity Araldite Highly Flexible Composite is simple.

Epocast 1614-A1 frozen epoxy syntactic is the basis of a range of preformed Eposert inserts.

Eposert inserts are produced in custom diameters, lengths and configurations in order to meet customers' specifications.

They are void-free (X-ray inspected), resulting in higher compressive strength than conventional techniques at temperatures up to 177C.

Moreover, they exhibit handing advantages, lead to higher productivity and have no transportation or storage limitations.

Eposert epoxy insert range can reduce the time required to reinforce honeycomb sections by up to 95 per cent by eliminating weighing, mixing, gelling and curing procedures.

The precision obtained by using Eposert epoxy inserts reduces the quantity of reinforced materials used, hence reducing the part weight.
