Description
The TQC Sheen Pretreatment Test Kit (PTK) is a complete inspection solution designed to assess and verify the performance of pretreatment processes on steel and aluminium substrates before coating application. Pretreatment — such as cleaning, degreasing, iron phosphate or conversion coating — is critical to ensure proper coating adhesion, corrosion resistance and long‑term performance.
This kit provides the essential tools required to perform a variety of pretreatment checks, including surface contamination testing, visual assessment of conversion coatings, and quantitative evaluation of pretreatment quality. By enabling accurate and repeatable assessment of substrate condition, the Pretreatment Test Kit helps laboratories, quality control teams and applicators confirm that surface preparation meets project or specification requirements before coating application.

Why Pretreatment Testing Matters
Proper pretreatment of metal surfaces removes contaminants such as oils, greases and soluble salts, and creates a suitable surface profile or chemical conversion layer to promote adhesion and corrosion protection. Inadequate pretreatment can lead to coating failure, corrosion under the coating, reduced adhesion and poor overall performance.
The PTK test kit brings together key test methods that help inspectors verify cleaning and pretreatment effectiveness, supporting quality assurance throughout the coating process.
