**Hangzhou Anfeili Technology Co., Ltd. - Expert Analysis on the Proper Application of Auxiliary Insulating Varnish**
Mr. Tan from Hangzhou Anfeili Technology Co., Ltd. (Phone: 152-6818-6621) provides an in-depth explanation on the correct use of auxiliary insulating varnish, a critical component in many electrical and electronic applications. While American Doffer's series of insulating varnishes are well-known globally, not everyone fully understands their proper application. This article aims to clarify how these products should be used and why they are essential in modern insulation systems.
Doffer Insulation Paint, also known as Fan Lishui, is a product of Doffer, a U.S.-based company that has been active in China for decades. Specializing in insulating materials, Doffer offers a wide range of liquid insulation products designed to improve the performance of transformers, motors, and coils. Their products reduce noise caused by electromagnetic forces while enhancing electrical strength and insulation resistance.
One key function of auxiliary insulating varnish is to protect the primary insulation—such as enameled wire—from damage during the manufacturing process. After the initial insulation, auxiliary varnishes are applied to reinforce the system, offering properties like moisture resistance, mildew resistance, corrosion resistance, and UV protection. These characteristics make them ideal for high-voltage and low-voltage applications alike.
It’s important to note that no single insulating varnish can fulfill all insulation requirements. For example, enameled wire lacquer may offer a smooth finish but lacks the durability and temperature resistance of auxiliary insulating varnishes. The latter is typically rigid and forms a protective layer, much like a man and woman coming together to form a complete family.
In practical terms, motor and transformer coils are often impregnated with auxiliary insulating varnish after being coated with enameled wire. This step ensures better mechanical strength, insulation integrity, and long-term reliability. Doffer’s CC-1105, a solvent-free high-temperature insulating varnish, is widely used for this purpose due to its low viscosity, high adhesion, and environmental friendliness.
Another popular product is BC-359H, a low-temperature baking insulating varnish. It offers fast drying, strong bonding, and excellent chemical and wear resistance. Certified to UL CLASS H (180°C), it is suitable for automated production lines and meets strict pollution prevention standards.
AC-43 is another versatile option, capable of self-drying or being baked at low temperatures. It is ideal for various applications such as impregnation, brushing, and spraying. With a quick curing time and high dielectric strength, it is widely used in electrical components, coils, motors, generators, and PCBs.
When purchasing Doffer insulating varnishes, it’s crucial to buy from authorized agents to ensure authenticity and quality. Be cautious of unverified sellers offering unusually low prices, as this could indicate counterfeit or substandard products.
