Our coating solutions support marine, oil & gas, manufacturing, infrastructure, and architectural projects — providing marine coatings, protective systems, powder coatings, and flooring solutions tailored to industrial performance requirements.
Technical FAQ
Coating Selection & System Types
How do I choose the right marine coating for my vessel or structure?
The correct coating depends on exposure conditions, substrate type, maintenance access, and required service life. Buyers should consider whether the structure is immersed, in splash zones, or exposed to UV, then select systems designed specifically for those conditions.
What is the difference between epoxy coating and polyurethane coating?
Epoxy coatings provide strong corrosion resistance and adhesion, making them suitable for primers, tanks, and structural protection. Polyurethane coatings offer better UV resistance and color retention, which makes them suitable for topcoats exposed to sunlight.
What coating is suitable for areas constantly exposed to seawater?
Areas exposed to seawater typically require high-performance epoxy systems designed for immersion conditions. These coatings provide strong adhesion, corrosion resistance, and protection against water penetration.
How do I know which coating system is suitable for long-term protection?
Suitable systems are usually backed by performance data, international standards compliance like ISO, and successful use in similar environments. Reviewing technical data sheets and project references helps buyers evaluate long-term reliability.
Application & Surface Preparation
What surface cleanliness standard is required before coating?
Most industrial systems require a minimum of Sa 2.5 (Near-White Metal Blast) per ISO 8501-1 for immersed or highly corrosive environments. Atmospheric exposure may permit Sa 2 or St 3. Correct profile depth (typically 40–70µm Rz) is equally critical to ensure adhesion.
Can coatings be applied in high humidity or tropical conditions like Malaysia?
Yes, with the right product selection. Several Hempel and International Paint systems are formulated for tropical application — tolerating up to 85% RH. Surface temperature must remain at least 3°C above dew point. Our technical reps can advise on humidity-tolerant primers if scheduling around weather is impractical.
What application methods are supported — brush, roller, or spray?
All three methods are supported and product data sheets specify the recommended approach. Airless spray is most common for large steel structures. Brush and roller are ideal for stripe-coating edges, welds, and bolt heads. Always confirm tip size and pressure from the product TDS to avoid film defects.
Performance & Maintenance
How long can I expect an industrial coating system to last?
Lifespan varies by environment and DFT achieved. A properly applied 3-coat epoxy–polyurethane system in a C3 atmospheric environment can deliver 15–20 years before major maintenance. Immersed or offshore C5-M environments typically see 5–10 year maintenance cycles. Regular inspection schedules extend system life significantly.
Can I overcoat an existing coating without blasting?
In many maintenance scenarios, yes — provided the existing coating is sound, well-adhered, and free of contamination. Spot-blast corroded areas to Sa 2.5, power-tool clean surrounding areas to St 3, then apply a compatible maintenance primer. Compatibility must be confirmed with the overcoating product’s data sheet.
Project Planning & Supplier Evaluation
Does MPC provide technical support and on-site inspection?
Yes. Our technical team offers pre-job consultations, coating system recommendations, and on-site quality inspections. We can assist with coating schedules, DFT monitoring, and documentation for owner/class society approval. Contact us early in the project lifecycle for the most effective support.
What documentation is available — TDS, SDS, approvals?
Full Technical Data Sheets (TDS), Safety Data Sheets (SDS), application guides, and relevant third-party approvals (e.g. Lloyd’s Register, DNV, BV) are available for all products we distribute. Request documentation via our contact team or visit the respective brand portals we can direct you to.
How do I get a quotation for a large project?
Reach out to our team directly Zac (+6014-383 9192), Mr. Loh (+6012-388 1689), or Mr. Phang (+6012-783 6687). Provide your surface area estimate, environment category, and any spec documents. We’ll prepare a competitive system recommendation with pricing.
