Huntsman Araldite’s advanced encapsulation and impregnation systems play a dual role in modern electronic and e‑motor applications. They serve as high‑performance adhesives for bonding components—ensuring robust mechanical integration—and as protective encapsulants that provide electrical insulation, thermal management, and environmental resistance.
The Core Products
The range is structured into three technology families:
1. Two-Part Epoxy Adhesives:
- Araldite® 2011: Versatile with a long open time.
- Araldite® 2012: Offers versatility coupled with fast curing.
- Araldite® 2014-2: Delivers excellent environmental resistance plus chemical and thermal stability.
- Araldite® 2015-1: Load resistant and effective for bonding dissimilar substrates.
- Araldite® 2019 (AW 4859/HW 4859): Known for high mechanical properties and resistance up to 140°C.
- Araldite® 2031-1: A black, thixotropic adhesive ideal for bonding composites and polyamides.
- Araldite® 2051: Provides ultra-fast curing for extreme conditions.
- Araldite® 2028-1: A clear, fast-curing formulation suitable for applications where aesthetics or transparency are important.
Huntsman’s next‑gen Araldite®/Aradur® epoxy systems deliver dual‑function performance in electric motor and PCBA applications. They serve as high‑strength adhesives to bond components and as encapsulants that provide excellent thermal conductivity, electrical insulation, and environmental protection. In electric motors, these materials improve winding impregnation and structural integrity—ensuring efficient heat dissipation, crack resistance, and long‑term reliability in high‑voltage and high‑power settings.
