PCS PCS Coating Systems and Specifications

Question 1

What document defines the coating system requirements, surface preparation standards, and acceptance criteria for a project?

Accepted Answer

Coating specification

Answer

A coating specification is the binding document that defines all technical requirements for a coating project, including prep standards, products, and acceptance criteria.

Question 2

Which coating system type is most commonly specified for structural steel exposed to industrial atmospheric conditions?

Accepted Answer

Three-coat zinc/epoxy/polyurethane system

Answer

A three-coat zinc primer, epoxy intermediate, and polyurethane topcoat system provides optimal corrosion protection and durability for industrial atmospheric steel.

Question 3

When a coating specification calls for a 'DFT' of 3–5 mils, what does DFT stand for?

Accepted Answer

Dry Film Thickness

Answer

DFT stands for Dry Film Thickness, the measured thickness of a cured coating layer expressed in mils (thousandths of an inch) or microns.

Question 4

A generic coating specification references 'SSPC-PS Guide 20.00.' What type of information does this guide provide?

Accepted Answer

Coating system selection guidance by environment

Answer

SSPC-PS Guide 20.00 provides guidance for selecting appropriate coating systems based on the service environment and substrate type.

Question 5

Which factor is MOST critical when selecting a topcoat resin type for a coating system exposed to UV radiation outdoors?

Accepted Answer

UV stability and chalk resistance

Answer

UV stability and chalk resistance are the primary topcoat selection criteria for outdoor exposure to prevent color fading and film degradation.
