Testing & Performance Data
Performance claims should come with numbers. Below are the published test results for each grade.

Salt spray test
Parts are exposed to a salt fog in a closed chamber; hours to first rust measure film resistance. Common references include ASTM B117, ISO 9227 and GB/T 10125.
Humidity test
Parts are held at 40 °C in a high-humidity cabinet to simulate storage and transport. Commonly referenced methods include GB/T 2361 and ASTM D1748.
Film thickness, flash point, viscosity
The KG-3 technical data sheet cites SH/T 0105 (film thickness), GB/T 261 (flash point), GB/T 265 (viscosity) and SH/T 0211 (service temperature).
Test results depend on substrate, surface condition, film thickness and application. They are typical values, not guarantees; request the current TDS before specifying.
