By the end of 2025, high-performance silicone sealants for construction are quietly transforming the market. Boosted by the “Good Housing” policy, ultra-low energy standards, and urban renewal, these sealants offer high durability, low VOC, self-cleaning, and photocatalytic features, emerging as hidden stars in green building materials.
Policy fuels demand:
New regulations require public and high-end buildings to use sealants with ≥25-year lifespan and ≤50 g/L VOC, phasing out traditional acrylics and polyurethanes. Silicone’s stability from -50°C to 200°C, 50+ year durability, and near-zero VOC make it the preferred choice.
Tech drives premium:
Leading companies launched smart products: TiO₂-enhanced sealants that break down air pollutants, anti-mold/shift hybrids for humid regions, and black conductive sealants for BIPV joints. Prices reach 35–50 CNY/kg, 2–3× normal sealants, with margins over 40%.
Urban renewal & exports:
Over 220,000 aging residential projects are being retrofitted, while demand from Belt & Road countries rises. China’s construction silicone exports grew 28% in 2025, led by Middle East and Southeast Asia.
With high technical and certification barriers, the top five brands now control 70%+ of the market. Silicone is no longer just a component—it’s the tech backbone of modern green buildings.
