Detailed introduction and selection guide for adhesive used for coil fixation

As a key component in equipment such as motors, transformers, sensors, and wireless charging modules, the stability of coils has a significant impact on the performance and lifespan of the entire device. Choosing the appropriate adhesive is particularly important to ensure the fixing effect of the coil and the safe operation of the equipment. This article will provide a detailed introduction to the types, performance requirements, application scenarios, and recommended products of coil fixing adhesives to help you find the best solution. Common types of adhesive used for coil fixationAccording to different application requirements, the commonly used adhesives for coil fixation mainly include epoxy adhesive, organic silicone adhesive, polyurethane adhesive, and acrylic adhesive. These adhesives have their own characteristics and can meet the fixed requirements of different scenarios.Epoxy adhesive is a type of adhesive known for its high strength and high temperature resistance. Its two-component or single component formula design is suitable for coil fixing applications such as motors and transformers that require high adhesion and insulation performance.Organic silicone stands out for its excellent flexibility, aging resistance, and resistance to mechanical stress, and is widely used in scenarios that require high resistance to vibration and high and low temperatures.Polyurethane adhesive combines high flexibility and impact resistance, making it ideal for devices where coils are sensitive to impact and vibration.Acrylic adhesive has fast curing speed and high bonding strength, making it suitable for applications in fast production lines.Key performance requirements for coil fixing adhesiveWhen selecting coil fixing adhesive, multiple performance requirements need to be considered to ensure the stability of the coil during long-term operation. Firstly, adhesive performance is the core indicator, and the adhesive needs to have strong adhesion to substrates such as copper, aluminum, iron cores, plastics, ceramics, etc., and be able to pass the pull-out test. Secondly, mechanical…
