1. Product Overview
Araldite Casting Resin System consists of Araldite MY 757, Araldite CY 223, and different hardeners (HY 842, HY 956 EN, HY 1473 BD). This system is designed for processing and curing at room temperature or slightly higher temperatures. It offers low initial viscosity, high filler addition possibility, good mechanical resistance, and resistance to atmospheric and chemical degradation. It is mainly used for encapsulating and potting low voltage and electronic components.
