1 Advanced Materials TECHNICAL DATA SHEET Araldite CY Resin GENERAL Liquid cycloaliphatic epoxy resin Araldite CY Resin is a very low viscosity resin, which offers high temperature performance, low and stable dielectric properties and superior arc, tracking and UV resistance. This product is recommended for the manufacture of high voltage electrical components to be used in aggressive outdoor environments. APPLICATIONS Insulators Bushings Transformers Wire and cable insulation Electrical connectors Electrical generators Motors Switchgear components PROPERTIES Low viscosity coupled with long working life High heat deflection temperature Excellent dielectric properties that remain low over a wide range of temperatures Superior arc, corona and tracking resistance High endurance under outdoor (UV) exposure TECH DATA* Specified data Color, APHA 100 maximum Epoxy Value, eq./kg Epoxy Equivalent, g/eq (77 ), g/cm 3 (lb/gal.)

2 FORMULATIONS Although Araldite CY Resin may be cured with nearly all carboxylic acid anhydrides, Aradur HT 907 is best recommended for outdoor electrical applications. Such systems offer superior arc & track resistance, excellent mechanical & electrical properties and very good handling characteristics, especially when used in conjunction with Accelerator DY 183. The properties of Araldite CY Resin systems at room temperature can be enhanced by the incorporation of the Flexibilizer DY 040. For example, by adding DY 040 at levels of 10-40phr, it is possible to improve the handling characteristics of the mixture, reduce the raw material cost and improve the mechanical performance of the cured system. Accelerator DY 183 is used at levels up to 12phr, dependent upon the mass and desired speed of cure. The Araldite cycloaliphatic epoxy systems exhibit a sharp decrease in viscosity with temperature. These low viscosities permit the incorporation of large proportions of inorganic fillers, e.g., over 400phr. or 65% by weight. The use of such fillers is recommended for casting for electrical or electronic applications to reduce exotherm, shrinkage, coefficient of linear thermal expansion, as well as cost. Processing: Araldite CY Resin is preheated to a temperature greater than the melting point of the anhydride used, e.g ( ) when using Aradur HT 907. Aradur HT 907 in its liquid state (>40 or 104 ) can then be added and mixed readily with the resin. The mixture can then be cooled to room temperature if desired. Accelerators and/or other modifiers such as DY 040 should then be added to the resin/hardener mixture at the desired process temperature. Separate mixtures of DY 040 and anhydride are to be avoided since there is a risk of a reaction between such components. Casting is best accomplished by using molds preheated to a temperature approximately 10 higher than that of the casting mixture. A practical procedure is to first mix the resin, hardener and modifier; then stir in the filler. Mix thoroughly under vacuum of 2 to 6 torr to de-air. The accelerator is best added last, immediately prior to casting. The pot life at room temperature, as measured by viscosity versus time, is in excess of eight hours. 100phr Araldite CY 179 US + 105phr Aradur HT phr Accelerator DY 183 remains below 4,000cPs for 16 hours at 25, exhibiting an initial viscosity of > 400cPs. * phr = parts per hundred parts, by weight, of resin Aug, 2013 Araldite CY Resin Page 2 of 6

3 EFFECT OF ELEVATED TEMPERATURES IN PROCESSING PROPERTIES OF CURED SYSTEMS Araldite CY Resin systems containing Accelerator DY 183, Aradur HT 907 and DY 040 exhibit the following typical processing characteristics at elevated temperatures: FORMULATION Parts by weight Araldite CY Resin Aradur HT Accelerator DY Flexibilizer DY mesh silica Hydrated alumina (~7 micron) Initial viscosity, cps at 40, (104 ) at 60, (140 ) ,000-2, ,000 at 80, (176 ) approx Pot life to reach 1500 cps, hr. at 40 (104 ) at 60 (140 ) at 80 (176 ) * Resin hardener and filler were combined using mechanical stirring at 90. The accelerator was then stirred in and entire mix placed in oven at 100. Curing is best accomplished by first gelling at 80 to 120 ( hour or more) followed by higher temperatures ( ) dependent upon the system used and the properties desired.
