Case study of water-based paint: the quality of water-based paint is unstable

Maintaining the stability of waterborne coatings is one of the keys to the success of waterborne coatings manufacturers. This is especially important for manufacturers of industrial waterborne paints. There are many reasons for the unstable quality of water based paint, such as water-based paint process,water-based paint formula and water-based paint raw materials.

Matter

Jiangsu some coating company waterborne wood matte white finish quality is good, a few furniture factory use the effect is very good. However, there are always problems with recent products. Formula and raw materials remain unchanged. The manufacturerasks hua jinsi what is the problem that causes quality problem of water paint product, and how to make quality of water paint product stable.

Scene investigation

The professional technicians of Sinograce Chemical visited the factory in person and found that the quality of the water-based wood lacquer made just now was very good, and the inspection was no problem. However, after storage for a period of time, the product return coarse, adhesion is not good, poor hiding power, quality is not stable. Poor customer performance.

Analysis

No problem with formula data and process. It is preliminarily concluded that the problem lies in the raw materials of waterborne wood lacquer.

Sinograce Chemical technicians conducted a series of comparative tests in the laboratory for several possible problems and soon found abnormalities in titanium dioxide. Dispersants have little effect on its dispersion. Scraper fineness shows wet film shrinkage, gloss is not normal, and fineness and qualified. As a result, particle agglomeration will

occur in the finished product after a long time, and coarse return will be easy to appear, leading to the decline of adhesion and poor covering power.

After determining the problem of titanium dioxide, huazinsi's professional and technical personnel carried out the verification experiment again, and the result proved that the problem was caused by the quality difference of titanium dioxide. After several batches of titanium dioxide in the modulation of water-borne wood matte white finish, the results are very good: smooth film, various performance indicators are up to the requirements.

Solution

Sinograce chemical suggested that the quality of titanium dioxide batch problems, guide customers to replace titanium dioxide varieties. Sinograce Chemical advised customers to further use the newly selected titanium dioxide storage stability test. A week later, the customer feedback sample is very good, excellent quality. Coating manufacturer has sent the product to furniture factory, response is good.
