Rapid electrochemical assessment of paint
8 Dec 2025The Rapid Electrochemical Assessment of Paint (REAP) is a procedure designed to estimate the long-term corrosion resistance of coated metals or to test the quality control of coated products.
Explore this guide on how to conduct REAP testing using Gamry's PTC1 paint testing cell, based on a proposed method being considered by the American Society for Testing Materials (ASTM).

Surface Area TestingPhysisorption studies fundamental parameters essential for the characterization of materials such as the specific surface area and pore size distribution. Properties such as porosity, strength, hardness, permeability, separation selectivity, corrosion, and thermal stress resistance can all be directly correlated to the porous structure of a material.Electrochemical CellCorrosion
