Organic silicone waterproofing agent is a material widely used in the fields of construction and waterproofing, featuring various types and properties. The following is a detailed classification and description of organic silicone waterproofing agents: 
Methyl silicic acid sodium and methyl silicic acid potassium: 
。 Properties: They can all be made into powder form and liquid form. The liquid form of methyl silicic acid sodium usually contains a concentration of 30% and 40% in the market, while the liquid form of methyl silicic acid potassium typically has a concentration of 42% and 52%. 
。 Waterproofing principle: Their waterproofing principles are similar. They are all of the penetrating type waterproofing agents. Due to their extremely small molecules, they can penetrate into the interior of building materials and form a waterproof layer. 
。 Application: Both of these waterproofing agents can be used for waterproofing treatment of building concrete. They can be added internally to the concrete or diluted and sprayed on the surface of the building. 
2. Hydrogen-containing silicone oil emulsion: 
。 Properties: This is an oily waterproofing agent, which is the product obtained after emulsifying hydrogenated silicone oil. The oily waterproofing agent does not mix with water, but when emulsified into an emulsion, it can mix with water. Its typical contents are 30% and 50%. 
。 Waterproofing principle: The molecules of hydrogen-containing silicone oil emulsion are relatively large and mainly serve for surface waterproofing. When the poly-silicone emulsion is heated above 140℃, the poly-siloxane molecules are oriented on the fabric, with the hydrophobic group -CH3 facing outward, forming a waterproof layer. 
。 Application: Due to its oily nature, hydrogenated silicone oil emulsion is more suitable for waterproof treatment of surfaces such as glazed tiles, ceramic tiles, floor tiles, and ceramics. 
3. Water-based and oil-based silicone waterproofing agents: 
Type: Organic silicone waterproofing agents are divided into water-based and oil-based types. The water-based organic silicone waterproofing agent is colorless or light yellow, while the oil-based one is transparent. 
。 Application: 
The water-based organic silicone waterproofing agent is suitable for use in the construction industry, exterior wall finishes, underground projects, ancient-style buildings, water tanks, bricks and tiles, cement, gypsum products, as well as for waterproofing, moisture-proofing and anti-pollution treatment of rural rooftops. 
The oily silicone waterproofing agent is mainly used for waterproofing treatment on glazed surfaces, tiles, floor tiles, ceramics, etc. 
In conclusion, organic silicon waterproofing agents include various types such as sodium methyl silicate, potassium methyl silicate, and hydrogen-containing silicone oil emulsions. Each type has its own unique properties and application scenarios. When choosing and using them, it is necessary to match them according to specific waterproofing requirements and material characteristics.
