Heavy duty coating refers to the relatively conventional anti-corrosion coatings, the corrosion can in a relatively harsh environment applications, and has to achieve a longer protection than conventional anti-corrosion coating of a class of anti-corrosion coatings.

Features of heavy-duty coatings
① It can use in harsh conditions, and have long-lasting anti-corrosion life of heavy-duty coatings in the chemical atmosphere and ocean environments, and can be used for more than 10 or 15 years, even in acid, alkali, salt and solvent medium in and Under certain temperature conditions, it can also be used for more than five years.
② Thick film is an important indicator of heavy anti-corrosion coatings. Coating anti-corrosion coating of dry film thickness of about 100μm or 150μm, and heavy-duty paint dry film thickness of 200μm or 300μm in the above, there is 500μm ~ 1000μm, even up to 2000μm.

The main difference between a conventional heavy-duty coatings and anti-corrosion coatings in its high technology content, large technical difficulty, involving technological advancement and product development in many ways, it is no longer over-reliance on the knowledge and experience of paint, but on electronics, Knowledge and the intersection of physics, ecology, machinery, equipment and management of multi-disciplinary, integrated and efficient, dispersants and rheological additives of high corrosion-resistant resin application, the development of new corrosion impermeability pigments and fillers, advanced construction tools application, construction and maintenance technology, on-site detection technology, integrated application to require heavy-duty Coatings and being.
