Scope

Reference definitions for paint-cell terminology used in feasibility reviews, equipment selection, process setup, and production planning.

Best used for

Best used to create shared vocabulary across engineering, purchasing, operations, integrators, and external suppliers.

Use with caution

Definitions do not replace equipment datasheets, coating TDS/SDS documents, or site-specific compliance review.

Evidence basis

Compiled from TD engineering terminology, project scoping language, and equipment-integration workflows.

Cure time is the duration required for paint to reach its final hardness and properties after application. This includes both flash-off time and final cure, affecting throughput, handling, and quality.

Why it matters in paint cells

  • •Determines buffer space and handling requirements
  • •Affects overall throughput and takt time
  • •Quality depends on proper cure conditions

Cure types

  • •Air dry: Ambient cure, slowest (hours to days), minimal equipment
  • •Force dry: 60-80°C, accelerates air-dry coatings
  • •Bake cure: 120-180°C, required for thermosetting coatings
  • •UV cure: Seconds, requires specialized lamps and coatings

Cure verification

  • •Pencil hardness or MEK rub tests for cure confirmation
  • •Adhesion testing (cross-hatch) verifies film integrity
  • •Cure window tracking ensures time-temperature profile met
  • •Under-cure often shows as soft film or poor solvent resistance
