Professional Hand Lay-up & Filament Winding Resins
Proven resin systems for traditional composite fabrication. Engineered for optimal fiber wet-out, controlled reactivity, and consistent mechanical performance in tanks, pipes, and structural laminates.
The Foundation of Composite Fabrication
Lechi hand lay-up and filament winding resins are the workhorses of the FRP industry. These versatile formulations provide the perfect balance of working time, viscosity, and curing speed for both manual laminating and automated winding operations. Our Isophthalic and Orthophthalic grades offer superior corrosion resistance and mechanical strength for chemical storage tanks, pressure vessels, and piping systems. With controlled thixotropy for vertical applications and excellent air release properties, these resins ensure consistent, high-quality laminates in every production environment.
