Heavy-Duty Anti-Corrosion Resins

Elite-tier chemical-resistant resins designed for the most aggressive industrial environments. Superior resistance to strong acids, alkalis, and oxidative salts with exceptional thermal stability.

Maximum Protection for Industrial Infrastructure

Lechi anti-corrosion resins include Isophthalic, Bisphenol A, and specialized Vinyl Ester formulations tailored for extreme chemical services. These resins form a dense, cross-linked polymer network that acts as a permanent barrier against molecular penetration of corrosive fluids. Engineered for the fabrication of GRP tanks, pipes, scrubbers, and electrolytic cells, our resins maintain their mechanical integrity where metals and general-purpose plastics fail. We offer specific grades optimized for diverse processes including filament winding, hand lay-up, and RTM.

Superior resistance to H2SO4, HCl, and NaOH
High Heat Deflection Temperature (HDT) up to 130°C
Excellent mechanical strength for structural equipment
Low permeation rates for long-term safety
Global compliance for chemical and water storage
