¡¡¡¡Today, there are many new types of coating being developed and available on the market. Anti-corrosion coatings are divided into standard and heavy-duty categories according to their anti-corrosion properties. There are also coatings categorized by the amount of working surface preparation needed called "Rusty Surface coatings" which can be applied onto rusty surface with minimal surface preparation.

¡¡¡¡Heavy-duty coatings are undoubtedly the most important industrial anti-corrosion coating but the strict requirement with regard to preparing any surface for coating (for example drying and sand blasting) mean that the full protection offered by the Rusty Surface Coatings is seldom achieved without scrupulous 'pre-coating' surface preparation.

¡¡¡¡During the early nineties Japanese companies and US successfully developed some innovative work-saving heavy-duty anti-corrosion coatings which can be applied directly onto rusty surfaces with out the need for sand blasting. These new products changed the face of Rusty Surface Coatings.

¡¡¡¡Wishing to compete in world markets, in 1993 Qunly successfully developed the Qunly BW9300 series providing a work saving, heavy-duty anti-corrosion coating. Technical Data has shown that Qunly BW9300 coatings are more effective than competing products. The BW9300 coatings are the ideal long lasting anti-corrosion protection for metal or concrete structures in the Chemical, Ship Building, Power Generation and Steel Manufacturing industries without need for regular maintenance and service even in the most adverse conditions.
