Key performance of wallpaper coating and its detection method

Wallpaper coating is a kind of coating applied to walls, usually composed of polymers, pigments and additives, whose main role is to improve the color, texture and protection performance of the wallpaper surface. They can be applied to all kinds of indoor walls, such as residential, office, shopping mall, hotel, etc., with rich colors, good durability and easy cleaning, etc., while improving the beauty and service life of the wall. Wallpaper paint usually has a variety of effects, such as matte, bright light, metal, paint, stone, etc., suitable for a variety of interior decoration styles and needs.

Key performance of wallpaper coating and its detection method

Step of detection
Dry film thickness: Use a thickness gauge to measure the dry film thickness of the wallpaper coating, record the measured value and calculate the average value.

Tensile strength and elongation at break: tensile tests were carried out using a tensile testing machine, test data were recorded and tensile strength and elongation at break were calculated.

Water resistance: Use a water circulation device to place the wallpaper paint in water, record the time and observe the change of the coating.

Wear resistance: Wear tests were carried out using a wear testing machine, test data were recorded and wear resistance was calculated.

Temperature resistance: use high and low temperature test box to simulate different temperature environment, observe the change of wallpaper coating.

Chemical resistance: Use a chemical tester to test the chemical resistance of wallpaper coatings.
