Corrosion Protection Solutions
Based on ISO 12944 international standards, we provide systematic anti-corrosion coating solutions for different corrosion environments. From C1 indoor dry environment to CX extreme corrosion environment, we have mature matching systems.
Confirm indoor/outdoor service, humidity, UV, immersion risk, chemicals, temperature, abrasion, and cleaning process.
Steel, galvanized steel, concrete, aluminum, wall surface, or existing coating all require different preparation and primer choices.
A complete system normally includes surface preparation, primer, optional intermediate coat, and a compatible topcoat.
Before quotation, confirm current TDS/SDS, packaging, shelf life, color, export requirements, and application conditions.
Use the sections below to narrow the coating family and system structure before requesting a quotation. The final selection should still be confirmed against substrate preparation, corrosion class, application method, destination regulations, and current Qilu Paints TDS/SDS.
Select protection system by corrosion environment grade
For indoor dry environments such as office buildings, residences, and dry warehouses with low corrosion risk
For rural atmospheres and unheated buildings with occasional condensation, such as small factories and gyms
For urban and industrial atmospheres with moderate humidity and pollution, such as chemical plants and high-humidity production areas
For chemical atmospheres and coastal salt spray environments, such as chemical plants, coastal buildings, and swimming pools
For high-humidity and aggressive chemical atmosphere environments, such as coastal offshore platforms, chemical plants, and pulp mills
For extreme corrosion environments, such as offshore oil platforms, marine structures, and highly aggressive chemical environments
For very very high corrosion environments, such as offshore oil platforms, marine structures, and highly aggressive chemical environments
Common coating questions by substrate, environment, and project use case
For structural steel, start with blast-cleaning requirements and corrosion class. Common systems use epoxy zinc-rich or epoxy anti-rust primer, epoxy intermediate coat, and polyurethane or fluorocarbon topcoat for exterior color retention.
Tank and chemical areas need careful review of medium, vapor exposure, cleaning process, splash risk, and temperature. Epoxy, glass flake epoxy, chlorinated rubber, or specialty coatings may be selected after confirming service conditions.
Outdoor infrastructure often combines anti-corrosion primer, high-build intermediate coating, and weather-resistant topcoat. Maintenance windows, salt exposure, and expected durability should be clarified before selecting the system.
Floor systems depend on concrete strength, moisture, traffic load, chemical exposure, slip resistance, and shutdown time. Epoxy primer, epoxy mortar or self-leveling layers, and topcoat should be selected as a system.
Machinery coatings balance appearance, drying speed, adhesion, impact resistance, and production rhythm. Acrylic, alkyd, polyurethane, epoxy, and baking finishes may be suitable depending on substrate and line conditions.
Wet service needs closer review of immersion, humidity, chemical cleaning, and substrate. Chlorinated rubber, epoxy, and specialty coatings should be checked against the current TDS/SDS and service environment.
For hot surfaces, confirm continuous and peak temperature, thermal cycling, substrate preparation, and whether the coating is decorative, anti-corrosion, or heat-indicating. Silicone products are common candidates.
Wall systems need substrate evaluation, putty or leveling layer, primer compatibility, alkalinity, moisture, color requirements, and local environmental rules. Waterborne and architectural products are frequent options.
Use these as starting points, not final specifications
Surface preparation -> anti-rust or zinc-rich primer -> epoxy intermediate coat when required -> polyurethane or fluorocarbon topcoat.
Cleaning or sanding -> alkyd or epoxy primer -> compatible enamel or industrial topcoat.
Confirm VOC limit and substrate -> waterborne primer -> compatible waterborne topcoat -> verify drying and recoat conditions.
Inspect existing coating -> remove loose film and corrosion -> spot primer -> compatible repair coat or full system rebuild.
