Methyl Acetate
Methyl acetate is a colorless, transparent liquid with an aromatic smell. The solubility in water at 20℃ is 31.9g/100 ml water, and it is miscible with alcohol and ether. It is easily hydrolyzed to generate acetic acid, making the solution acidic. It decomposes into acetaldehyde and formaldehyde when heated at high temperatures, and can further decompose into methane, carbon monoxide and hydrogen.

Product advantages
- Miscible with most organic solvents;
- It has a wide range of dissolving power and can dissolve acrylic, vinyl,nitrocellulose, epoxy, polyurethane, polyester, phenolic resin, etc.;
- Compared with acetone, it has a higher flash point and higher anti-whitening performance, and can better meet the requirements of coatings, paint process formulas and users;
- In the process formula that needs to use low boiling point volatile organic solvent, it can replace the application of ethyl ester, acetone and methyl ethyl ketone;
- In polyurethane shoe materials, it can replace cyclopentane, chlorofluorocarbons, etc. as an environmentally friendly foaming agent;
- VOC-Exempt Regulation Status is exempt from restricted conditions, environmentally friendly solvents.
