🏗️ Engineered for Demanding Civil Engineering Projects
Infrastructure assets face constant exposure to harsh environments—from UV and salt fog to chemical spills and high humidity. YQXPOLYMER’s CSM S30L is a spray-grade chlorosulfonated polyethylene (CSM) that delivers superior, long-lasting protection for both steel and concrete substrates across bridges, tunnels, parking structures, and marine facilities.

🔧 Key Applications of YQXPOLYMER CSM S30L in Infrastructure
🌉 1. Bridge and Viaduct Coatings
CSM S30L forms a flexible yet tough coating that adheres strongly to metal surfaces. It resists UV degradation, prevents salt-induced corrosion, and remains durable even under long-term environmental cycling.
Benefits:
High UV resistance
Salt spray and corrosion protection
Flexible film with excellent adhesion
Extended service life in outdoor conditions
🚇 2. Waterproof Coatings for Tunnels & Parking Garages
Spray-applied CSM S30L creates a seamless, elastomeric barrier that shields concrete from water ingress, chloride attack, and environmental contaminants—ideal for subterranean infrastructure.
Benefits:
Excellent waterproofing performance
Crack-bridging ability
Durable in high-humidity, enclosed spaces
Anti-carbonation barrier for concrete
⚠️ 3. Chemical-Resistant Containment Linings
CSM S30L is inherently resistant to a wide range of acids, alkalis, solvents, and fuels—making it the ideal coating system for secondary containment areas, such as refineries, chemical zones, and industrial spill basins.
Benefits:
Exceptional chemical resistance
Non-permeable membrane
Easy maintenance and inspection
Long-term protection from spills and leaks
🌊 4. Coastal & Marine Concrete Protection
With outstanding resistance to saline water and marine atmospheric corrosion, CSM S30L helps extend the lifespan of coastal infrastructure like seawalls, docks, and offshore platforms.
Benefits:
Marine-grade salt fog resistance
Anti-chloride penetration
Resistance to algae, erosion, and freeze-thaw cycles
Compatible with anti-fouling systems
