Application of Organic Silicon Building Waterproofing Agent

Sep 26, 2024

Organic silicon coatings have very low surface tension and excellent waterproof performance. In addition, their superior cold resistance, heat resistance, elasticity, and weather resistance make them widely used as waterproof and moisture-proof coatings, especially for building and material waterproofing, with very satisfactory results.Moisture intrusion is the main cause of damage to concrete and masonry buildings. In order to extend the service life of buildings, it is best to use a waterproofing agent on the surface of buildings that can prevent moisture intrusion without hindering the escape of internal moisture. Silicone resin is the preferred waterproof coating that can meet the above requirements. Buildings treated with organic silicon waterproof and moisture-proof coatings can prevent rainwater infiltration and extend their service life, with an effective lifespan of 10-15 years.

Sodium alkyl silanol is a relatively inexpensive water-soluble waterproof and moisture-proof coating. It has reactive silanol groups that can form a strong bond with the surface of the material. The sodium silanol group can react with carbon dioxide in the air to form new silanol groups and also form new binding bonds. It is easy to construct and not limited by the dryness or wetness of the substrate. By adjusting the ratio of phenyl and methyl groups, a coating with both good water permeability and waterproofing can be obtained. Therefore, it is widely used as a waterproof and moisture-proof coating in architecture, and has important value in the restoration of ancient buildings and brick and stone artworks.

Organic silicon building waterproof coating, also known as building waterproofing agent, has excellent properties such as waterproofing, weathering resistance, anti peeling, and chemical corrosion resistance.
The waterproofing principle of organic silicon building waterproofing agent is different from common waterproofing materials such as organic coatings and asphalt. Organic coatings and asphalt achieve waterproofing effect by blocking the pores of masonry and concrete structural materials; Organic silicon building waterproofing agents react chemically with structural materials to form several molecules thick insoluble waterproof resin films on the surface of the substrate.
Due to the fact that organic building waterproofing agents do not block the pores of building materials, they not only have water repellency, but also maintain the normal ventilation of buildings, which is their biggest advantage. Buildings treated with organic silicon building waterproofing agents can maintain cleanliness, be dust-free, improve the thermal and sound insulation performance of buildings, and prevent surface cracking caused by freeze-thaw cycles, thereby preventing or reducing weathering and extending the service life of buildings.

The construction of silicone waterproofing agent can be carried out through methods such as spraying, brushing, and impregnation, or by mixing it with cement and mortar. Their application areas include roof tiles, surface tiles and porcelain floor tiles, prefabricated concrete components, aerated concrete and asbestos cement, interior and exterior walls, renovated concrete surfaces, natural stone building reinforcement and waterproofing, adding silicone resin to other coatings and building materials, external mortar and mortar joints, base coatings, etc.
