Silicone waterproofing materials are primarily divided into three major categories, each with unique properties and applications.

1. Methyl Potassium Silicate (First Category): This water-soluble alkaline compound forms a breathable waterproof layer after curing. It is widely used for moisture protection on building exteriors and concrete structures, offering both environmental friendliness and durability.

2. High Hydrogen-Content Silicone Oil (Second Category): Through the reaction of active hydrogen with substrates, it forms a hydrophobic film, providing excellent permeability and weather resistance. It is particularly suitable for deep protection of porous materials such as stone, brick, and tile.

3. Silicone Resin (Third Category): By cross-linking reactions, it forms a three-dimensional network structure, delivering a high-strength waterproof coating with outstanding resistance to high and low temperatures. It is commonly used on metal roofs, glass curtain walls, and other surfaces requiring strong adhesion.

These three types of materials achieve waterproofing through different mechanisms. Users can select the most suitable option based on substrate characteristics, construction environment, and budget considerations. Methyl potassium silicate is ideal for large-scale applications, high hydrogen-content silicone oil excels in deep penetration protection, and silicone resin is best for complex surface treatments.
