Silicone Water Repellent Manufacturers Introduce The Main Uses Of Water Repellents

Update:2022-09-09 00:00

Water repellents are known to reduce the water permeability of mortar and concrete under hydrostatic pressure. And this through the water repellent improves the internal density of the concrete to achieve its role in improving the impermeability of the concrete. In addition, it should be noted that the hydrophobicity of the hydrophobic agent is the embodiment of the hydrophobic effect on the surface of the material. There are very similar silicon-oxygen bonds between the structure of silica crystals (such as quartz, etc.) and the three-dimensional structure of silicone resin cross-linked macromolecules. Mineral materials have a greater affinity. Therefore, when the water vapor (or raindrops) in the air touches the surface of the material, the hydrophobic surface of the material can exert its hydrophobic effect, making it difficult for liquid water to stay on the slope and facade, and finally achieve The effect of preventing the penetration of external moisture into the interior of cement-based materials. In addition, the water repellent is "breathable", so it can maintain the moisture balance of the covering itself (and thus further improve its durability). Below, Silicone Water Repellent Manufacturers introduce the main uses of water repellents:

1. water repellent is mainly used in cement dry powder building materials. The water repellent can greatly reduce the water absorption rate of the material because it can impart excellent water repellency to the material, and even improve its anti-contamination ability without affecting the flexural strength and compressive strength of the material (does not affect the material. paintability, etc.).

2. The water repellent can also be used in facing mortar, caulking agent, gypsum products, tile adhesive, water-resistant putty, waterproof coating, and cement-based mortar with impermeability and waterproofing.

3. The water repellent can be used in various construction projects (in all walks of life) that need to be waterproof, seepage, and moisture-proof. Among them, it can be mainly used in basic engineering roofs, kitchens, basements, civil air defense projects, walls, toilets, In subways, tunnels, pools, water towers, swimming pools, dams, docks, and other construction projects with impermeability and waterproofing requirements.
