Orientación rápida de recubrimiento
Empiece aquí antes de la calificación técnica
Use estas primeras orientaciones para elegir una familia aproximada de recubrimientos. La selección final depende del sustrato, la preparación de superficie, la exposición, las normas y los documentos.
Maintenance repainting where blasting is limited or old coating remains
Calificación primeroSurface-tolerant epoxy or rust-tolerant primer plus polyurethane or compatible topcoat
Use when site preparation capability is the constraint and final recommendation must check the existing coating.

Preguntas de selección
- What asset is being protected, and is it new build, factory finish, or maintenance?
- Which exposure risks matter most: corrosion, UV, water, chemicals, abrasion, heat, fire, hygiene, VOC, or throughput?
- What result should be optimized: lowest initial cost, balanced protection, longer maintenance interval, production speed, lower VOC, appearance, or surface-tolerant maintenance?
- Which cooperation route fits the buyer: product supply, system package, OEM, distributor, project support, or local supply-chain collaboration?
Preparación de superficie
- Confirm substrate condition, oil, salts, dust, rust, laitance, old coating, and surface profile
- Match preparation grade to the selected system and expected durability
- Run adhesion or compatibility checks when old coating remains
Condiciones de aplicación
- Confirm substrate temperature, ambient temperature, humidity, dew point margin, ventilation, and drying window
- Review film thickness, recoating interval, pot life, and handling time from current TDS
Colores y embalaje
- Standard colors and practical finish targets can be reviewed before quotation
- Special colors, gloss, texture, and private-label packaging need sample or batch confirmation
Documentación disponible
- Current TDS
- SDS request
- Packaging and shelf-life check
- Export document review
- Basic application notes

Sistemas Essential / Standard / Extended
Essential
Lowest practical initial cost where exposure and durability requirements are moderate.
- Confirm substrate and preparation level
- Use a simple primer and finish route suitable for the service class
Final product selection depends on current TDS and project constraints.
Standard
Balanced protection, application practicality, and document support for normal commercial procurement.
- Confirm primer and topcoat compatibility
- Use a system schedule matched to exposure and handling needs
Recommended as the default review route for most inquiries.
Extended Service
Longer maintenance interval, stronger weathering resistance, or more aggressive exposure.
- Increase barrier build where justified
- Use higher durability finish options when UV or color retention matters
Requires stronger review of surface preparation, inspection, and film build.
Maintenance / Surface-Tolerant
Maintenance work where full blasting is limited and old coating may remain.
- Identify old coating and remaining corrosion
- Use compatible maintenance primers only after review
Loose rust, oil, salts, powdery coating, and weak old film still need removal.
