Maintenance coatings for fast repair, easy application and long-lasting protection
Maintenance coating systems are designed to restore protection on weathered or damaged surfaces with minimal disruption to operations. Applicators require products that are easy to apply in the field, dry quickly, adhere well to aged substrates, and deliver durable corrosion resistance over time. Maintenance coatings must also offer compatibility with existing paint systems to ensure seamless touch-up and refurbishment.
Synocure® acrylic polyols for efficient maintenance & DTM topcoats
For 2K maintenance and DTM topcoats, Synocure® acrylic polyols provide a versatile combination of adhesion, flexibility and weathering performance with economical isocyanate consumption. These properties make them ideal for field repairs and refurbishment cycles on steel structures, machinery and industrial assets exposed to outdoor conditions. Key product examples include:
- SYNOCURE® 862 X 55 — fast-dry economical favorite for field repairs
- SYNOCURE® 878 N 60 — versatile "go-to" grade for maintenance & DTM
Together, these resins enable maintenance coatings that can restore protection quickly and extend the life of coated assets with minimal downtime.
Synolac® and Unithane® alkyd resins for seamless field application
For 1K maintenance coatings, Arkema’s Synolac® and Unithane® ranges deliver easy application, strong adhesion, UV durability and corrosion resistance in a cost-effective package. Their field tolerance and fast-dry profiles support touch-up operations, overcoating, and repairs on multi-coat systems in industrial and marine environments. Relevant maintenance grades include:
- Synolac® 5014 X 60 — fast dry ally for quick return-to-service
- Synolac® 563 — cost and performance conqueror
- Synolac® 7503 X 60 — corrosion protector with chemical & UV durability
- Unithane® 655 WD 55 — abrasion resistance booster for tougher maintenance scenarios
These solutions also support sustainability objectives through bio-based content, lower VOC profiles, and optimized film build for reduced environmental footprint.
Multi-layer or DTM systems for balanced protection and durability
Multi-layer and DTM (Direct-to-Metal) coatings require a careful balance of corrosion resistance, UV durability, film hardness and application efficiency. In these systems, acrylic polyols enable primers, intermediates and topcoats that together withstand aggressive weathering, salt spray and mechanical stresses. Arkema provides resin grades delivering an excellent balance of performance and cost across multi-layer and DTM systems, such as:
- SYNOCURE® 570 X 65 — durable, straightforward champion for primer & DTM
- SYNOCURE® 9237 S 70 — resilient low-VOC star for balanced performance
- SYNOCURE® 867 BA 60 — robust performer for improved outdoor durability
These systems deliver effective corrosion protection and longer service life across infrastructure, industrial equipment, transport and marine applications.
High-build coatings for maximum corrosion resistance and service life
High-build coatings are designed to deliver higher film thickness per layer, improving barrier performance against corrosion and extending durability in severe service environments. These systems are widely used in offshore, marine and industrial infrastructure, where salt spray, chemical exposure and mechanical stresses accelerate coating degradation. Applicators also seek low VOC, solvent-free or high-solids solutions that reduce the number of coats while maintaining long-term performance.
Arkema enables high-build coatings through SYNOCURE® acrylic polyols for polyurethane topcoats and CRAYAMID® reactive polyamide hardeners for epoxy primers and intermediate layers. Together, these technologies provide the combined corrosion resistance, chemical performance and mechanical robustness required to extend the lifespan of critical assets.
Synocure® acrylic polyols for durable high-build PU topcoats
High-solids acrylic polyols help formulators achieve thicker film build, improved barrier properties and excellent exterior durability. They support high performance in C4/C5 and offshore environments. Examples include:
- SYNOCURE® 9279 S 70 — premium performance pioneer
- SYNOCURE® 866 EEP 75 — long-lasting leader for weathering performance
- SYNOCURE® 9226 BA 82 — the 250g/L groundbreaker for high-solids build
These topcoats contribute to enhanced corrosion resistance and extended service life under marine and industrial exposure.
Crayamid® reactive polyamides for high-build epoxy primers
For epoxy-based primers and intermediate coats, CRAYAMID® reactive polyamide hardeners deliver outstanding mechanical and chemical resistance, excellent adhesion and proven anticorrosive performance. Their inherent surface tolerance and humidity compatibility support high-build coatings applied on steel surfaces in real-world conditions. Relevant grades include:
- Crayamid® 140 — solvent-free, low viscosity, corrosion protection
- Crayamid® 195 X 60 — fast surface dry & excellent compatibility
- Crayamid® 230 X 60 — strong cure properties in extreme humidity & wet conditions
- Crayamid® 960-100 — solvent-free, long pot life, corrosion protection
These systems are widely used in Protective & Marine assets where harsh operational environments demand thicker films, strong barrier performance and high resistance to aggressive chemicals.
Safer for workers, lower carbon footprint, and no compromise on performance — Arkema’s newest acrylic polyol emulsion unlocks waterborne NISO 2K coatings that deliver a more sustainable path forward for industrial applications.
Industrial coatings are evolving toward safer and lower-VOC 2K technologies. Arkema’s NISO and HAPS-free solvent solutions deliver these benefits without sacrificing performance. Case studies highlight both approaches.
