2K Epoxy Potting Compound Araldite 229-3/Aradur HY 229-1

Liquid, hot-curing two-component epoxy casting system with excellent crack resistance. Prefilled with slightly abrasive, mechanically reinforcing fillers.

FEATURES:

Outstanding mechanical and electrical properties combined with very high crack and thermal shock resistance due to the low coefficient of thermal expansion.
Qualified for encapsulation of large metal parts.

APPLICATIONS:

Indoor electrical insulation material for postinsulators
Equipment parts
Bushings
Instrument and dry type distribution transformers
Switchgears, …

PROCESSING METHODS:

Automatic pressure gelation process (APG) (see our special brochure, Publ. No. 28160/e)
Conventional gravity casting process under vacuum
