Chemical park sewage pools contain hydrogen sulfide gas, mixed acid wastewater and corrosive sludge, causing severe pit corrosion on concrete and steel substrates. Traditional epoxy lining needs long curing time and forms seam gaps prone to medium leakage. Modified polyurea solves all pain points of sewage tank anti-corrosion.

FLDC two-component spray modified polyurea complete lining system for industrial chemical sewage facilities:

1. Epoxy penetration sealing primer for concrete base sealing
2. Modified polyurea base layer, ultra-fast curing within seconds
3. Polyurea top coat with anti-mildew additive Core Advantages: ✅ Instant curing after spraying, no construction downtime waiting ✅ Fully seamless integral film, zero medium leakage risk ✅ Resist hydrogen sulfide, organic acid and sludge long-term erosion ✅ Excellent flexibility, no cracking under foundation settlement ✅ Wide construction temperature range (-10℃ ~ 45℃) We supply polyurea lining solutions for chemical industrial park renovation projects worldwide.
