Application to purchase fields

automotive coating efficiency

Line efficiency is a purchase question, not a performance claim from this desk. Capture transfer efficiency method, film-build window, oven schedule and waste handling so quotations stay comparable.

  1. 01 Coverage basis: theoretical, measured, or still undefined
  2. 02 Cure schedule and substrate temperature range
  3. 03 Viscosity window that the robot or booth can hold
  4. 04 SDS flash point and waste classification for the same fill

Trade-off the matrix cannot hide

Waterborne systems often reduce flash-point burden and reported VOC, but they can change booth humidity control and flash time. Solvent-borne systems may fit an existing oven, yet they move UN number, storage and waste cost. Neither route is declared better here. The RFQ should name the process the plant can actually run.

Coverage slogans without a substrate, film-build and method do not belong in a price cell. If two factories use different coverage math, we keep both numbers and the methods instead of averaging them.

Typical limits we write on the brief: efficiency numbers are method-dependent; moisture or temperature outside the TDS window can void a comparison; hazardous-material handling follows the SDS, not this matrix.

What we ask the factory to restate

If a supplier mentions automotive coating efficiency, the reply should cite the test method, panel type, atomizer, and whether the number is first-pass transfer or material utilization. Without those, the claim stays in the open column.

What stays with the buyer

Robot programs, booth air balance and waste permits are site conditions. We do not convert a TDS sentence into a plant guarantee.

Convert the application note into an RFQ

Add substrate, film-build window, atomizer type and bake schedule so automotive coating efficiency numbers stay tied to a method instead of a slogan.
