Permeable crystalline waterproof coating is an active substance with active silicon molecular structure, with small molecular weight and both hydrophobic and hydrophilic groups.
Its hydrophilicity is greater than hydrophobicity, it is soluble in water, and condensation crystallization does not occur in dry environment, but occurs in wet environment.
It is made of active silicon, cement and active inorganic mixture.
Permeable crystalline waterproof coatings are rarely used in daily life.
It can be used for waterproof construction of basements, roofs, toilets and bathrooms in civil buildings, as well as maintenance and plugging of all concrete structural defects such as concrete building facilities.
2. Crystal formation conditions:
Polycondensation crystallization occurs when the concentration of active aqueous solution increases, and the active crystallization masterbatch is dissolved in water during cement hydration or wet surface construction of wet cement products, and dispersed in cement products with water.
However, with the increase of time, water participated in the hydration reaction of cement, and some water was lost by volatilization, which led to the increase of active aqueous solution concentration and polycondensation crystallization.
Extended data:
Product features:
1, automatic defect repair
The active substance sealed by the coating can produce secondary crystallization at the defects of the base layer when it meets water, which has the function of automatically repairing defects such as microcracks and has strong resistance to the changes of the base layer.
2, good physical and chemical properties
Strong permeability and alkali resistance.
3. Good waterproof effect
Can really achieve a construction, lasting waterproof, eliminating the trouble of annual maintenance.
4. Good environmental protection performance
This product takes water as solvent, which is green, nontoxic, tasteless and pollution-free, and can be used for waterproof treatment of drinking water.
5, the construction is convenient
It can be used for the construction of water front and back of concrete structure.
