Special methyl silicone oil for building materials undergoes comprehensive upgrade. Green building waterproof and demolding materials usher in a widespread adoption trend. 

1.Urban renewal boosts demand for building materials, and methyl silicone oil becomes a core waterproofing additive.
With the continuous implementation of old residential area renovations, prefabricated buildings, and underground pipe galleries projects, the market size of building waterproofing, concrete demolding, and gypsum board processing has steadily expanded. Methyl silicone oil, due to its excellent hydrophobicity, lubricity, and weather resistance, has become a mainstream functional raw material. Traditional oily additives tend to turn yellow and pollute the base surface. The water-based emulsified methyl silicone oil formula gradually replaces the old products and is suitable for various waterproof construction scenarios such as exterior walls, roofs, and tunnels. The consumption of special silicon oil for building materials in the industry has maintained double-digit growth for consecutive years. 

2. Water-based low-VOC formulation is mass-produced, meeting the requirements of new building environmental protection regulations
The new building environmental protection standards strictly limit the volatile pollutants of construction additives. Solvent-based silicone oil products are gradually restricted. The industry has launched solvent-free and low-ring-body water-based methyl silicone oil, which is refined through multiple stages of evaporation. The residual silicon oxide is far below the national standard limit, and there is no pungent smell during construction, and no harmful substances are released after completion. This series of products have obtained green building certification and are suitable for indoor and outdoor construction of commercial housing, public venues, etc., effectively avoiding the risk of project environmental acceptance. 

3. Multi-functional Modified Silicone Oil Solves Key Problems in Concrete Construction
Ordinary methyl silicone oil only has a single demolding effect. The new modified building silicone oil integrates multiple functions such as lubrication, waterproofing, and anti-adhesion. When used for pouring of plain concrete and prefabricated components, the demolding is smooth without any sharp corners, and the mold surface is not prone to accumulation of dirt. This can extend the service life of the mold. After thousands of dry-wet cycle tests, the water absorption rate of the concrete treated with the silicone oil has significantly decreased. It can resist the erosion of rainwater and underground moisture, and is highly suitable for coastal high-salt and high-humidity construction projects. 

4. The large-scale production of special silicone oil for gypsum boards expands the application scope of interior building materials
In the production of paper-faced gypsum boards, self-leveling gypsum, and artistic gypsum sculptures, special methyl silicone oil can enhance the water repellency and surface smoothness of the boards, preventing wall dampness and mold growth. The addition of emulsion-type methyl silicone oil is convenient, has good compatibility with gypsum slurry, does not affect the curing speed of gypsum, and the demand for high-end waterproof gypsum production lines is continuously increasing. Relying on stable domestic supply, the auxiliary material procurement costs of building materials enterprises continue to be optimized, helping to promote the large-scale popularization of green prefabricated building materials.
