Achieve heat resistance up to 300 °C
with Epoxy resins

Resins: Epoxy resins (Tactix® 742, Tactix® 556, Araldite® MY 9721, Araldite® MY 0510) Application: Industrial Composites (Transportation, Electronics, General Industry ...) > Key Benefits Highest heat resistance (up to 300°C Tg) with Tactix® 742 Medium viscosity and High Tg with Araldite® 9721 Very low viscosity and High Tg with Araldite® MY 0510 Lowest water absorption and High T with Tactix® 556

In demanding applications such as Transportation, Electronics, Electrical insulation or General Industry it is crucial that the end-use product resists to high and very high temperatures without sacrificing other properties such as processing or water resistance for instance, first to ensure a trust relationship experience with customers and second for developers to produce thermosets with properties that will remain unchanged overtime.

Huntsman Advanced Materials has a very broad portfolio of specialty multifunctional epoxy resins. The strong partnership relations created with its customers allows them to propose customized solutions. Formulators are guaranteed that their needs are met according to the application and the performance that they have to reach.

Very high heat resistance up to 300°C or High heat resistance combined with high water resistance

Huntsman Advanced Materials proposes epoxy resins exhibiting the highest Tg or the highest water resistance among commercial epoxy resins

The graphs below show comparisons of Huntsman Advanced Materials Tactix^® epoxy resins and Araldite^® Epoxy Novolacs, with reference to bisphenol A based epoxy resin (DGEBA), with the following test conditions:

• Tg comparison - Ultimate Tg DMA (Max tan δ, °C)
• Stoichiometric cure with 4,4'-DDS
• Cure cycle: 3h at 180°C + 2h at 230°C

Figure 1: Tactix^® 742 enables highest Tg among commercial epoxy resins

Figure 2: Tactix^® 556 illustrates the lowest water absorption among commercial epoxy resins

Figure 3: Araldite^® resins can reach very high
glass transition temperatures

High heat resistance up to 250°C and easy processing

Huntsman Advanced Materials proposes epoxy resins with low viscosity that enables easy handling and processing combined with high thermal resistance of the cured products.

• Glass transition temperature by DMA
• Stoechiometric cure with 4,4'-DDS
• Cure cycle: 3h at 180°C + 2h at 230°C
