Manufacturer: Wuxi HuiLong Electronic Materials Co., Ltd. Automobile ignition coil with epoxy potting compound (Potting) formulation of the principle of design: vehicle-cylinder gasoline engine with the fuel and air mixture is achieved by high-voltage electric spark ignited. Ignition coil is the formation of such a high-voltage electric discharge of high pressure components, high voltage of 30 kV and above, so handle the ignition coil is to increase the insulation strength of its product quality, reliability and the key to life. Coil in the air insulation solution is the best way to deal with the use of vacuum resin casting process, the so-called resin vacuum casting process is the first casting resin potting compound vacuum defoaming processing, drying and then after a pre-drying treatment, to be packaged the ignition coil on the vacuum casting chamber for pre-vacuum drying so that the coil and the frame, line between the shell package with all the exhaust gas, and then used in a vacuum under the conditions of the bubble is completely unable to have a good potting compound has been mixed encapsulation. Which you vacuum potting material used for good? Experts said that all aspects of an inspection is the preferred epoxy resin. In the choice of vacuum potting material can be made in accordance with the use of environmental technology resin potting compound conditions. Currently used in automotive ignition coil potting compound resin mainly polyurethane, silicone and three kinds of epoxy resin, in which polyurethane and silicone elastomers are, from the casting conditions, equipment conditions, dielectric strength, cost and sources of raw materials , the optimal resin.

Experts said that the other should be noted that: Automotive ignition coil epoxy potting compound the technical requirements for curing materials with excellent electrical performance, the product should have excellent high and low temperature impact resistance, durability and non-cracking, and specifically automobile ignition coil is epoxy potting compound the technical requirements for hot and cold impact resistance -40 ~ 120 ℃ / h, 400 cycles life test of 140 ℃ environment ≥ 1000h, internally or rely on such products are mainly imported, the Japanese company Somar , Switzerland, Ciba Corporation, the United States Ther-moset plastics companies have products in this area. Done a better job domestic Wuxi HuiLong Electronic Materials Co., Ltd.( http://www.wlepoxy.com), product quality and Japanese counterparts at the same level. Motorcycle ignition coil with the epoxy potting compound should be able to withstand peak voltage 35kV, open trial lasted 1 min without breakdown and surface discharge damage in -40 ℃ and 80 ℃ for each to maintain a cycle of 1h, A total of five temperature cycle test without damage, strengthen the durable life of more than 240h, motorcycles epoxy potting compound with the major emphasis on performance pressure. The appearance of epoxy potting compound can be seen: Automotive ignition coil used in the potting compound viscosity, and heated to above 110 ℃ until viscosity decreased rapidly, and added more packing capacity; and motorcycle ignition coil used in irrigation seal material viscosity smaller, heated to 60 ℃ on the rapid decline in the viscosity, less filler.
