ARALDITE® CW 5801-1 / ARADUR® HY 5801

ARALDITE® CW 5801-1 / ARADUR® HY 5801 is a two-component, epoxy-based potting and encapsulating system. ARALDITE® CW 5801-1 / ARADUR® HY 5801 is a 100% solids (no solvent) two-component, epoxy-based potting and encapsulating system designed especially for applications requiring very low shrinkage and excellent dielectric characteristics. Although the system will gel at room ambient temperature, an additional short elevated temperature post-cure is recommended to achieve optimal properties. This product is recommended for the encapsulation of electrical and electronic components.

Storage & Handling

Storage Conditions

Araldite® CW 5801-1/Aradur® HY 5801 components should be stored in a dry place and in the sealed original containers at temperatures between 2°C and 40°C (36°F and 104°F). Under these storage conditions the shelf life for each product is 1 year. The products should not be exposed to direct sunlight. Some filler separation may occur in the Araldite® CW 5801- 1 component during storage. Prior to use it should be re-homogenized by gentle stirring to prevent air entrapment.
