All-in-One Water What are the key performance features? You can check out the details below.

　　1. Appearance of Varnish Water: The varnish water paint liquid is uniformly transparent, free from cloudiness or milky appearance, contains no mechanical impurities, and produces a smooth, even coating film.

　　2. Viscosity of all-purpose water-based coatings: All manufacturers adjust their formulations to achieve the right viscosity, ensuring that the coating material penetrates effectively and achieves optimal paint retention when immersed.

　　3. Solid Content of Solvent-Based Coatings: Solid content applies exclusively to solvent-based paints. Currently, the international recommendation favors coatings with high solid content and low viscosity. In China, the solid content of insulating varnishes typically meets or exceeds 45%. For solvent-free coatings, the curing percentage is usually used as the measurement standard. For most solvent-free coatings, the content of volatile components after curing should not exceed 15%.

　　4. Drying Time: To save energy and enhance efficiency, there should be a strong push to promote the use of insulating paints that dry quickly and cure at low temperatures.

　　5. Thick-layer Curing Capability: This is a key technical indicator for evaluating the overall performance of insulating varnishes. It requires the thick layer to cure uniformly, free of bubbles and cracks, and to remain as flexible as rubber.

　　6. Flexibility: The insulating varnish produced by Fanli Shui manufacturers must exhibit excellent flexibility (elasticity) and strong adhesion—it shouldn’t be overly brittle. Typically, the paint film is tested by bending it 180 degrees around a 3 mm mandrel; under this test, the film should remain intact without cracking, let alone peeling off.

　　7. Insulating Properties: Fanli water-based insulating paint boasts high dielectric strength and volume resistivity. Typically, its normal dielectric strength exceeds 70 kV/mm, while the volume resistivity is above 10.

　　8. The role of paint on enameled wire: All coil windings should use enameled wire, ensuring that the insulating impregnation varnish is compatible with the wire and does not corrode its surface insulation layer. The impact of paint on enameled wire is typically measured by pencil hardness. According to industry standards, the paint applied to enameled wire must have a pencil hardness of at least 1H.

　　9. General water-based corrosion resistance: The insulating impregnation varnish exhibits excellent resistance to solvent vapors, moisture, salt spray, and thermal shock.

10. Mechanical Strength of Varnish: Insulating varnish must exhibit high mechanical strength, meaning it should have excellent adhesion, high viscosity, and superior resistance to mechanical impact.

　　All manufacturers of varnish explain that prolonged exposure to varnish is harmful to health. The raw materials used to produce the varnish include some substances that are toxic, and in some cases, even highly poisonous. Additionally, the organic solvents typically employed in the manufacturing process are also predominantly toxic. For instance, long-term exposure to aromatic solvents like benzene, toluene, and xylene can lead to chronic poisoning, as well as symptoms such as thrombocytopenia and leukopenia. In severe cases, acute poisoning may occur, potentially resulting in shock. Therefore, there is always a risk of toxicity—and it’s crucial to remain vigilant, cautious, and meticulous—throughout the transportation, storage, handling, and production of both the water-based products and their raw ingredients.
