Advanced CIPP & Pipeline Rehabilitation Resins
Specialized UV-curing and thermal-curing resin systems for trenchless pipeline repair. Engineered for rapid installation, structural strength, and long-term chemical resistance in sewer and water infrastructure.
Trenchless Technology for Infrastructure Renewal
Lechi CIPP resins represent the forefront of trenchless pipeline rehabilitation technology. Our dual-cure systems (UV and thermal) enable rapid, in-situ pipe repair without excavation, dramatically reducing project costs and community disruption. The Isophthalic and Vinyl Ester formulations provide exceptional resistance to sewage chemicals, groundwater, and industrial effluents, while maintaining high flexural strength to restore structural integrity to deteriorated pipes. With optimized viscosity for felt impregnation and controlled exotherm for thick-wall liners, these resins ensure complete cure and long-term performance in buried infrastructure.
Quick Stats
Application Fields
Engineered for Rapid Rehabilitation
UV-LED Cure Technology
Advanced photoinitiator systems enable rapid curing with UV-LED trains, allowing for high-speed liner installation and same-day return to service.
Thermal Cure Reliability
Hot water and steam curing options provide consistent, full-depth cure in large-diameter pipes and complex geometries where UV shadowing may occur.
Structural Restoration
High modulus and flexural strength enable the liner to function as a standalone structural pipe, extending service life by 50+ years.
Manufacturing Process Compatibility
Our Pipeline Repair Resins series is meticulously formulated to integrate seamlessly into your existing manufacturing infrastructure, from high-precision molding to heavy-duty winding.
