A chemical plant experienced severe corrosion issues in production pipelines due to long-term exposure to acidic/alkaline media, with some pipe walls thinning by over 30%, posing safety risks. Traditional epoxy coatings provided insufficient corrosion resistance, requiring recoating every 2 years at high maintenance costs.
Solution: MC-800 High-Solid Polyurethane Anti-Corrosion Coating
– Superior Corrosion Resistance: Certified to ISO 12944 C5-M, resistant to chemical media at pH 2-12
– Long-Term Protection: Lab-accelerated corrosion tests show coating remains intact for over 5,000 hours in 80°C acidic environments
– Fast Application: Surface dries in ≤15 minutes, supports curing at -10°C, minimizing downtime
Construction Data
▶ Total pipeline length renovated: 1.2km
▶ Construction period: 40% shorter than original solution (completed in just 5 days)
▶ Inspection results: Coating thickness ≥250μm, adhesion meets GB/T 9286-1998 Grade 1 standard
Customer Feedback
“After using PU-800, the pipelines have operated corrosion-free for 18 months, with an expected protection period exceeding 8 years and annual maintenance costs reduced by 60%.” — Lu Gong, Plant Equipment Department
