ARALDITE® CY 5910 / ARADUR® HY 1102 / ACCELERATOR DY 062 / ARALDITE® DW 9134 / Silica

ARALDITE® CY 5910 US is a toughened cycloaliphatic epoxy resin. ARADUR® HY 1102 is a fully saturated liquid anhydride curing agent, and ACCELERATOR DY 062 is a liquid tertiary amine necessary to initiate the epoxy-anhydride reaction. ARALDITE® DW 9134 BD is a cycloaliphatic epoxy-based gray color paste formulated to give an ANSI 70 gray color to cured components. With the addition of silica filler, preferably silanized, casting systems can be prepared that are recommended for use in harsh environmental applications in the medium voltage and heavy power electrical industry. These systems offer excellent thermal shock resistance combined with a high glass transition temperature.

To determine whether cross-linking has been carried to completion and the final properties are optimal, it is necessary to carry out relevant measurements on the actual object or to measure the glass transition temperature. Different gel and post-curing cycles in the manufacturing process could influence the cross-linking and the glass transition temperature respectively.

General Instructions

Long pot life is desirable in the processing of most casting systems. Mix all of the components together very thoroughly at room temperature or slightly above (up to 60°C ) under vacuum. Thorough wetting of the filler is extremely important. Proper mixing will result in:

-better flow properties and reduced shrinkage

-lower internal stresses resulting in improved mechanical properties in cast components

-improved electrical properties in high voltage applications For mixing of medium to highly viscous casting systems and for mixing at lower temperatures, the use of a thin film de-gassing mixers is recommended as this type of equipment may produce additional heating of 10°C to 15 °C as a result of friction.

For low viscosity systems, conventional anchor mixers are usually adequate. In larger plants, two pre-mixers are used to mix the individual components (resin and hardener) with the respective quantities of fillers and additives under vacuum. Metering pumps then feed these mixtures to a final mixer that can be either static or dynamic. The individual mixtures can be stored at elevated temperatures ~60°C (~140°F) for up to approximately one week, depending on formulation. Intermittent agitation during storage is advisable to prevent filler separation. Mixing time can vary from 0.5 to 3 hours, depending on mixing temperature, quantity, mixing equipment and the particular application. The recommended vacuum is 0.5 to 8 mbar. For dielectrically highly stressed parts, it is recommended to pre-dry the fillers to remove any residual moisture. The moisture content of the fillers should be ≤ 0.2 weight %.

The effective pot-life of the mixed system is approximately 1 to 2 days at temperatures below 25°C (77°F). Conventional batch mixers should be cleaned once a week or at the end of work. For longer interruptions of work, the pipes of the mixing and metering installations must be cooled and cleaned with the resin component to prevent sedimentation and/or undesired viscosity increase. Interruptions over a weekend without cleaning are possible if the pipes are cooled at temperatures below 18°C (64°F). For information regarding viscosity increase and gel time at various temperatures, refer to Figures.1 and 3.
