Types and Properties of Heavy Anticorrosive Coatings

　　 Heavy-duty anti-corrosion coatings Compared to conventional anti-corrosion coatings, they can be used in more demanding corrosive environments and provide a longer protection period. Heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years or more in chemical atmospheric and marine environments, and even in acid, alkali, salt, and solvent media, and under certain temperature conditions, they can be used for more than 5 years. Below, let's look at the types and properties of heavy-duty anti-corrosion coatings.

　　I. Heavy-duty anti-corrosion coatings Types of

　　1. Epoxy resin paint, thick-film epoxy zinc-rich primer, epoxy rust-proof paint, epoxy glass flake, epoxy coal tar pitch paint, epoxy floor paint; vinyl chloride paint, primer, topcoat, machine tool paint, hammer finish paint, fireproof paint, anti-corrosion paint, varnish, PVC putty.

　　2. Chlorinated rubber anti-rust paint, chlorinated rubber coatings of various colors, chlorinated rubber aluminum anti-rust primer, chlorinated rubber iron red aluminum anti-rust primer, chlorinated rubber primer anti-fouling paint; acrylic paint, acrylic polyurethane varnish, various acrylic polyurethane enamel paints, acrylic road paint; fluorocarbon coatings, fluorocarbon anti-corrosion coatings, metallic fluorocarbon coatings, fluorocarbon exterior wall coatings.

　　3. Alkyd paint, mica iron alkyd anti-rust paint, alkyd hull paint, alkyd enamel paint; silicone high-temperature resistant paint, various silicone air-drying paints, various silicone curing paints, silicone high-temperature resistant insulating paint, aluminum powder high-temperature resistant paint, sound-damping high-temperature resistant paint; solvent-free anti-corrosion coatings, solvent-free epoxy glass flake heavy-duty anti-corrosion coatings, solvent-free epoxy coal tar pitch coatings, solvent-free anti-corrosion coatings for pipe inner walls, solvent-free self-leveling floor paint.

　　II. Heavy-duty anti-corrosion coatings Properties of

　　1. Heavy-duty anti-corrosion coatings have good adhesion and physical-mechanical properties. Strong adhesion to steel substrates or other coated objects is a prerequisite for excellent heavy-duty anti-corrosion coatings, especially good wet film adhesion, low shrinkage, appropriate hardness, toughness, wear resistance, and temperature resistance.

　　2. The difference between heavy-duty anti-corrosion coatings and ordinary anti-corrosion coatings lies in their higher technical content and greater technical difficulty, involving multiple aspects of technological advancement and product development. Heavy-duty anti-corrosion coatings no longer rely solely on paint knowledge and experience, but on multidisciplinary knowledge and cross-integration from fields such as electronics, physics, ecology, machinery, equipment, and management.

　　Thick film is an important characteristic of heavy-duty anti-corrosion coatings. Heavy-duty anti-corrosion coatings can be applied in energy industries, such as power transmission and transformation equipment, coal mines, nuclear power, hydraulic equipment; transportation, such as bridges, automobiles, trains and railway facilities, containers, ships, highway guardrails, airport facilities, etc.; marine engineering, such as offshore platforms, coastal and bay structures; and large industrial enterprises, such as papermaking equipment, cement plant equipment, pipelines, and mining and smelting.
