Processing Information
- The ARALDITE resin component should be stirred and homogenized in the original container before use.
- The ARALDITE casting mix is best prepared by heating the ARALDITE resin up to 40- 50°C before stirring in the hardener.
- Brief degassing of the mix under 5-10 mbar vacuum improves the mixture homogeneity and enhances the dielectric properties of the castings.

Different gelling and cure cycles in the customer’s manufacturing process could lead to a different degree of cross linking and thus a different glass transition temperature.

Storage & Handling
- Storage and Handling Information
- Regular procedures approved by national and/or local authorities
- Store the components in a dry place at 18-25°C, in tightly sealed original containers.
- Under these conditions, the shelf life will correspond to the expiry date stated on the label.
- After this date, the product may be processed only after reanalysis.
- Partly emptied containers should be tightly closed immediately after use.
- Disposal: Regular procedures approvedand/or local authorities
