1 Aditya Birla Chemicals (Thailand) Ltd. (Epoxy Division) EPOTEC YDC 615 / TH 7652 P1 / TP 1 Liquid Hot Curing EPOTEC Casting Resin System YDC Pbw TH 7652P1 8 Pbw TP 1-8 Pbw Silica Pbw Description EPOTEC YDC 615 is a liquid modified DGEBA resin suitable for electrical casting applications. EPOTEC TH 7652 P1 is a liquid anhydride hardener and TP 1 is liquid flexibilizer, which can be added in appropriate ratio, upto 8 parts by weight. When appropriate quantity of hardener, flexibilizer, and filler are mixed with resin and casted under vacuum, very good mechanical and electrical properties with high uniformity can be achieved. This system is also capable to exhibit good resistance to altering high and low temperature, mechanical and electrical stresses and has outstanding dimensional stability. Processing Recommended for APG and conventional vacuum casting. Applications Electrical insulation for medium and high voltage applications such as switchgear components, bushings, post insulators as well as instrument and dry type distribution transformers.

This premixed resin and hardeners can be held for one week at 6 o C. In order to prevent the sedimentation of filler during storage, intermittent mixing is recommended.

5 Storage and handling EPOTEC YDC 615, TH 7652 P1 and TP 1 can be stored up to 1 year in sealed original container. Storage condition below 15 o C may cause crystallization of the resin as well as hardener. Crystallization may be reversed completely by heating the material to 5-6 o C. It is advised to use resin and hardener only when they are clear and free from cloudiness. Hardener TH 7652 P1 is sensitive to moisture thus partly emptied containers should be closed immediately after use.for handling and safety, please refer MSDS.
