    Generic Types of Protective Coatings: A Working Guide to the Chemistry

    Protective coatings are grouped by generic resin chemistry. Thermosets (epoxies, inorganic zinc silicates, polyurethanes, polyesters, vinyl esters) cure by chemical reaction and...

    Industrial Coatings: Types, Systems, and Surface Preparation Requirements

    Industrial coatings are protective systems such as epoxies, zinc-rich primers, polyurethanes, thermal spray metals, intumescents, high-temperature silicones and polyureas. Each family has...

    Performance Coatings: What They Are and What Surface Preparation They Require

    Performance coatings are industrial coating systems (high-build epoxies, zinc-rich primers, polyurethane topcoats, thermal spray metals, high-temperature and intumescent coatings) designed for aggressive...

    Corrosion Resistant Coatings: Why Surface Preparation Determines Whether They Work

    Corrosion resistant coatings protect steel by barrier, sacrificial (zinc) or inhibitive action, and all three depend on adhesion to properly prepared steel....

    Corrosion Protection Coatings: Metallic, Organic and Conversion Layers Explained

    Corrosion protection coatings fall into three families. Metallic coatings such as hot-dip galvanizing and thermal spray add a sacrificial or barrier metal...

    Surface-Tolerant Coatings: When Perfect Prep Isn't Possible — and Why Prep Still Wins

    Surface-tolerant coatings, typically aluminium epoxy mastics, are formulated to wet out and bond to imperfect hand- or power-tool-cleaned steel and sound, compatible...

    Intumescent Coatings: What They Are and What Surface Preparation They Require

    Intumescent coatings are passive fire protection coatings that swell when heated, from about 200–250°C, into an insulating char that delays the temperature...

    Surface Preparation for Heavy-Duty Coatings: A Substrate-by-Substrate Field Guide

    Heavy-duty coatings need two things at the substrate: the cleanliness and the anchor profile specified for the primer. Bristle blasting delivers both...
