In the automotive refinish coatings industry, product quality is a key factor in customers’ decision-making. As a professional refinish coatings manufacturer exporting to over 70 countries, WASHINTA always places quality control as the top priority. Today, we’ll take you “inside” our factory to reveal how we ensure that every can of refinish coating meets the highest standards.
1. Strict Selection of Raw Materials
Quality assurance starts at the source:
All our colorants, resins, additives, and solvents come from world-renowned suppliers.
Every batch of raw materials undergoes chemical composition analysis, stability testing, and color inspection before entering the factory to ensure compliance with our standards.
This step guarantees the base performance and long-term color stability of the coatings.
2. Advanced Production Equipment
To ensure uniformity and consistency in every batch, we have invested in modern production lines:
Fully automatic dispersion systems to ensure complete blending of colorants and resins;
High-precision filling equipment to guarantee accurate volume and ratios for every can;
Enclosed production environment to prevent dust and contamination, ensuring pure coatings.
High automation reduces human error and ensures stable, reliable product performance.
3. Strict Process Control
Every production step follows rigorous process standards:
Temperature, humidity, and mixing speed are precisely controlled;
Different types of coatings (solid colors, pearlescent, waterborne) follow independent production processes;
Every batch undergoes quality inspections, including viscosity, drying time, gloss, and adhesion tests.
Only products that pass all tests proceed to the next stage.
4. Comprehensive Quality Testing
Our laboratory is equipped with advanced instruments:
Spectrophotometers to ensure color matches standard samples;
Weathering testers to check coating stability under high/low temperature and humidity;
Mechanical performance tests to evaluate adhesion, hardness, and impact resistance.
Every can of coating undergoes multiple tests to ensure excellent performance in the customer’s hands.
5. Continuous Improvement and R&D Support
Quality is not only about production control—it also relies on continuous R&D:
Our professional R&D team continually optimizes formulas to improve color matching accuracy and coating durability;
Customer feedback is directly used to refine production processes, forming a closed-loop quality management system;
The application of new materials and technologies keeps our products at the forefront of the market.
Conclusion
The quality of automotive refinish coatings determines repair results and customer satisfaction.
From raw material selection, production equipment, process control, to rigorous testing and R&D support, we ensure the high quality of every can of coating through strict control at every step.
Choosing a professional refinish coatings manufacturer means choosing reliability, safety, and efficiency.
