Acetone in Paints and Coatings: Grade Selection and Procurement Guide

Acetone is a commonly used organic solvent and has a wide range of applications in the paint and coating industry. It is used not only as a solvent, but also as some additives or driers. Because the methyl and ketone groups in the molecular structure of acetone are easy to sublimate, it may cause yellowing or cracking of the paint or coating. Therefore, in the production of paints and coatings, the purity and grade selection of acetone is particularly important.

Acetone purity grades and uses

The purity grade of acetone is mainly divided into four grades: Grade A, Grade B, Grade C and Grade D. These grades are based on the purity and use of the acetone. Grade A acetone has a high purity and is usually used in the production of high-end acetone oxime and other high-value active reagents. The purity of grade B acetone is slightly lower than that of grade A, which is suitable for general use. Propyl-grade acetone has a lower purity and is mainly used in chemical experiments and industrial preparations. Acetone is of the lowest purity and is mainly used in laboratories and small-scale production.

KEY FACTORS OF ACETONE GRADE SELECTION

There are several key factors to consider when choosing an acetone grade. The use of acetone determines its purity requirements. If acetone is to be used in the production of high-value active reagents such as acetone oxime, first-grade acetone must be selected. The storage conditions of the acetone also affect the purity. Acetone is easy to decompose or absorb other substances in high temperature or humid environment, so it needs to be moisture-proof, dust-proof and high temperature-proof during storage. The purity of C is also related to environmental requirements. With the increasing awareness of environmental protection, many countries and regions have strict restrictions on the use and discharge of solvents, so the choice of environmentally friendly acetone has also become an important consideration.

Acetone storage and use precautions

The storage and use of acetone requires attention to the following points. Acetone is flammable and needs to be stored away from open flames and high temperature sources. Acetone is easy to volatilize at room temperature and needs to be well ventilated during storage. When using acetone, you need to operate in a well-ventilated place and avoid direct contact with skin and eyes.

Acetone Procurement Guide

When purchasing acetone, you need to pay attention to the following points. Choose acetone from regular manufacturers because these manufacturers have stricter standards of purity and quality control. Select products with the same nominal purity and actual purity to ensure that the product meets the requirements of use. Pay attention to the production date and shelf life of acetone and avoid using expired products.

As an important solvent in paints and coatings, the purity and grade of acetone directly affect product quality and environmental protection requirements. Choosing the right acetone grade, following the correct storage and use methods, and following procurement standards are important steps to ensure the quality of paints and coatings.
