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.

Film build refers to the accumulation of coating thickness, whether in a single pass or multiple coats. Managing film build is essential for achieving target DFT without defects.

Why it matters in paint cells

  • •Controls final appearance and protection level
  • •Affects cure time and process throughput
  • •Multiple thin coats often better than one thick coat

What to watch for

  • •Exceeding wet film limits causing runs/sags
  • •Inconsistent build across part surfaces
  • •Inter-coat flash time requirements
