Coating suppliers frequently face failures: paint films pass factory adhesion tests yet peel off at customers’ sites. The cross-cut, scribed-circle and pull-off tests assess coating adhesion from distinct perspectives and are not interchangeable. The cross-cut test enables fast qualitative batch screening for thin coatings. The scribed-circle test simulates local combined stress to comply with traditional specifications. The pull-off test delivers quantitative tensile data, mandatory for thick coatings, heavy-duty anti-corrosion works and bidding projects. A single passed test cannot detect hidden defects under thermal cycling or weathering. Our 3-tier QC system uses cross-cut for mass production, scribed-circle for re-inspection, and pull-off tests for engineering orders. Multi-testing eliminates “false pass” risks, guaranteeing long-term performance of water-based and powder coatings against peeling in industrial and heavy anti-corrosion applications.
A batch of water-based coatings and powder coatings were successfully sent to Türkiye. From on-site factory inspections by customers, formula customization to cross-border delivery, we provide low VOC environmentally friendly coatings, stable anti-corrosion and weather resistance performance, and full chain technical services, landing cooperation in the Asian and European markets, and continuously promoting the global layout of China's environmentally friendly coatings.
If the anti-corrosion coating is not done well, it will be troublesome in the later stage. Many construction sites and factories have encountered the problem of blistering, rusting, and peeling of the paint film shortly after spraying, which is time-consuming and time-consuming to rework, and also affects the project schedule and reputation. Today's article focuses on the three most common paint film problems in anti-corrosion construction, explaining the reasons, first aid plans, and prevention points in one go. Whether it is water-based anti-corrosion paint, powder, or heavy-duty anti-corrosion coatings, they can all be used.
With stricter environmental policies, water-based coatings have become an industry necessity. This article illustrates its five core advantages and one-stop oil-to-water solutions to help factories cut costs and gain more orders.
