| Project Overview

Three-proof paint, also known as protective paint or moisture-proof paint, is a specially formulated coating used to protect circuit boards and their components from environmental erosion. The testing of three-proof paint aims to evaluate its physical and chemical properties, curing properties, and three-proof performance, covering performance tests such as main component analysis, specific gravity, viscosity, solid content, surface drying time, glass transition temperature, adhesion test, water absorption rate, mold resistance test, salt spray test, gas corrosion test, and hydrolysis resistance evaluation. Ensure that the three-proof paint meets the reliability requirements of electronic equipment in harsh environments.

| Test Objective

1. Through physical and chemical performance tests such as main component analysis, specific gravity, viscosity, and solid content, ensure that its formula complies with design specifications and provides a stable foundation for subsequent processes.

2. Through curing performance tests such as surface drying time, glass transition temperature and adhesion tests, verify its curing efficiency and bonding strength with the substrate to avoid the risk of delamination or peeling.

3. Through three-proof performance tests such as mold resistance test, salt spray test, gas corrosion test, and hydrolysis resistance evaluation, verify the protective durability of the three-proof paint under conditions such as humidity, salt spray, and chemical corrosion to ensure the long-term stable operation of electronic equipment.
