QC Matters to Us All

WOTAI QC measures are implemented at every stage of the manufacturing process. We monitor and control the temperature, reaction time, and other critical processes. Regular sampling and testing are conducted to evaluate the additives’ quality at different stages. It may involve testing for viscosity, pH, solid content, particle size, and other indicators.

All Steps Involved for QC

Quality control begins with the inspection of raw materials. The first step is testing and verifying the raw material’s quality, purity, and consistency. WOTAI products include polymers, cellulose ethers, calcium formate, VAE RDP, superplasticizers, anti-foaming agents, concrete fibers, and others. We ensure all ingredients meet the specified standards and store them properly, free from contaminants.


Adherence to standard operating procedures (SOPs) ensures a smooth and efficient manufacturing process. Process control plays a crucial role in maintaining good quality of the final product. The results of different tests are in batch records. Serving as an essential documentation tool for traceability purposes. We ensure product traceability, quality assurance, and improvement in our operations.
