Epoxy resin : widely used as an electrical insulation material due to its excellent dielectric properties and mechanical strength. Epoxy resin has several properties that make it well-suited for electrical insulation.
Strong adhesion: Epoxy resin forms a strong bond to a variety of substrates, including metals, ceramics, and composites.
Excellent thermal and chemical resistance: Epoxy resin can withstand high temperatures and exposure to chemicals, solvents, and other environmental factors.
High dielectric strength: Epoxy resin can withstand high voltages without breakdown, making it an effective insulator.
Low dielectric constant and loss: Epoxy resin has a low dielectric constant and low dissipation factor, allowing it to minimize energy losses in electrical systems.
Epoxy resin is used in various electrical insulation applications, such as:
Transformer and motor windings: Epoxy resin is used to insulate the windings and coils in transformers, generators, and electric motors.
Switchgear and circuit breakers: Epoxy resin is used as an insulating material in the enclosures and components of switchgear and circuit breakers.
Electrical bushings and insulators: Epoxy resin is used to fabricate electrical bushings, insulating supports, and other insulating components.
Electrical potting and encapsulation: Epoxy resin is used to encapsulate and protect electrical components, such as sensors, connectors, and circuit boards.
When using epoxy resin for electrical insulation, it's important to follow these steps:
Mixing and application: Carefully mix the epoxy resin and hardener according to the manufacturer's instructions. Epoxy resin / Hardener / Filler: 100 / 100 / 350.
Curing: Allow the epoxy resin to cure fully according to the recommended time and temperature. This is crucial to ensure the desired dielectric and mechanical properties.
Storage：
The components have to be stored in tightly sealed and dry original containers in an environment at 6~35℃;. Under these conditions, the shelf life will correspond to the expiration date stated on the label ( normally 12 months). After this date, the product may be reanalyzed to confirm if it validates yet. Partial emptied containers should be closed tightly immediately after use.
First Aid:
If eyes are contaminated by epoxy resin, hardener or mixture for casting, the eyes should be treated and washed immediately by clean running water for 10 to 15 minutes. If necessary, the person shall be sent to hospital. If the skin is stained or splashed by the materials, it shall be wiped immediately and washed off by clean water. If the person feels very hurt or burn wounds, he or she shall be sent to hospital immediately. If the clothes are Contaminated, the people shall change the suits immediately. If the operator breathes in the vapour and feel bad, he or she shall be moved to outside. Any other doubt, please consult doctors or us for medical assistance.
