**Hangzhou Anfeili Technology Co., Ltd. – Expert Analysis on the Proper Use of Auxiliary Insulating Varnish**
Mr. Tan from Hangzhou Anfeili Technology Co., Ltd. (Phone: 152-6818-6621) is here to guide you through the correct application of auxiliary insulating varnish, a critical component in electrical and electronic manufacturing. If you're familiar with the American Doffer brand—also known as Dorf—you might know it as one of the world's largest manufacturers of liquid insulation materials. Their products are widely used by medium-to-high-end users for their excellent quality and reliability.
However, while many people recognize the brand, not everyone fully understands how to use these insulating varnishes effectively. In this article, we’ll break down the proper usage of auxiliary insulating varnishes and why they are essential in various applications.
### What is Doffer Insulation Paint?
Doffer Insulation Paint, also known as Fan Lishui, is specifically designed for auxiliary insulation in electronic components. It offers high adhesion, strong mechanical strength, and minimal shrinkage stress. Its key features include:
- Rigid structure
- High adhesion
- Excellent pressure and wear resistance
- Environmentally friendly
These properties make it ideal for applications such as motor coils, transformer coils, and other electrical components where insulation performance is crucial.
### Why Use Auxiliary Insulating Varnish?
While enamel wire lacquer is soft and smooth, its temperature resistance, voltage resistance, and adhesion are significantly lower than those of auxiliary insulating varnishes. These varnishes are typically rigid and form a protective layer that enhances the durability and performance of the primary insulation.
For example, after the coil is coated with enamel wire lacquer, an auxiliary insulating varnish is applied to protect against environmental factors like moisture, corrosion, and UV exposure. This secondary layer ensures long-term stability and improves the overall insulation system.
### Product Highlights

### Where to Buy?
It’s important to purchase from authorized agents of Doffer. Many online sellers may offer misleading prices, but real agents ensure product authenticity and quality. Avoid being deceived by low prices—genuine Doffer products are sold exclusively through verified channels.
### Final Thoughts
There is no single insulating varnish that can fulfill all insulation needs of a product. Each type serves a specific purpose, and using the right varnish at the right stage is crucial for optimal performance.
