The importance of waterproofing in home decoration is beyond doubt. The waterproof coatings on the market are different. Many professional terms make many consumers powerless. In fact, no matter what kind of waterproof coating, Yantai Jiu Asahi Waterproof tells you that as long as these performance indicators are not wrong:
. Solid content
Refers to the proportion of solids contained in the waterproof coating. The solid content is closely related to the thickness of the film and the quality of the coating, because the coating is formed by the solid content of the coating.
, Heat resistance
It is pointed out whether the waterproof film formed by the waterproof coating has high temperature properties such as softening deformation and non-flowing. It reflects the high temperature resistance of waterproof coatings. With high temperature and waterproof engineering, the indicators cannot be ignored.
. Low temperature flexibility
The performance of the membrane's waterproof coating is flexible at low temperatures. It reflects and builds on the low temperature performance of waterproof coatings.
Refers to no leakage performance in a certain water pressure waterproof coating (hydrostatic pressure and dynamic water pressure) and a certain period of time. It is the main quality index of waterproof coatings to meet waterproof requirements.
Strength and ductility
After the waterproof coating is formed, it must have a certain tensile strength and elongation in order to adapt to the basic deformation caused by temperature difference, dry and wet factors, and ensure
Waterproof effect. Bond strength
The waterproof coating must have a certain adhesion to the surface of the base layer. The basis for greater bonding strength and better bonding performance.
In addition, coatings with drying time and aging properties are also important. In short, the procurement of this waterproof coating must meet the relevant standards.
