Test Background
Mold resistance refers to the ability to tolerate or prevent or inhibit the growth and reproduction of mold spores and mycelium. The paint film mold resistance test can determine the mold resistance of various types of paint films.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various paint films and provides professional mold resistance testing services for paint films.
Scope of tests
1) According to use: there are wood paint, iron paint, glass paint, aluminum paint;
2) Divided by state: water-based paint and oil-based paint. Water-based paint is mainly latex paint, while lacquer paint, polyurethane paint, etc.;
3) According to the form of action: volatile paint and non-volatile paint;
4) According to the surface effect: transparent paint, translucent paint and opaque paint.
Test method
1. Simulate the environmental conditions for mold growth in nature and design accelerated tests according to the physiological characteristics of mold growth.
2. Inoculate mold spores on the surface of the sample, then place the sample for culture under environmental conditions suitable for mold growth, and observe the growth of mold on the surface of the sample.
3. Evaluate and grade the mold resistance of the paint film according to the degree of mold growth on the surface of the sample.
