Waterproof functional wall paint is mainly used in food production enterprise workshop wall coating system, household or public building toilets, hospitals, medical and electronic production workshops, schools, basements, clubs, commercial buildings, etc. Environments with special usage requirements.
The principle of waterproof wall paint can be divided into two types: one is to form a complete coating film to block the penetration of water or the penetration of water molecules; the other is to prevent water penetration through the hydrophobic effect of the coating itself. Pass. Polymer composite coatings can form a complete and continuous paint film after curing, and the width of the molecular gap is about several nanometers. Individual water molecules can pass through these gaps, but water in nature is usually in an association state, dozens of Due to the action of hydrogen bonds, water molecules form a large water molecular group. In fact, it is difficult for water molecular groups to pass through the gap between polymer coatings to cure the paint film. This is the main reason why the waterproof coating topcoat has waterproof function. reason.
