Methyl acetate has gradually become a mature product in the world, replacing acetone, methyl ethyl ketone, Ethyl acetate, cyclopentane and the like. In 2005, Eastman Company of the United States replaced Methyl acetate with acetone solvent. Because Methyl acetate is not a restricted organic pollutant discharge, it can meet new environmental standards for coatings, inks, resins and adhesives.

Stability and reactivity: stable
Hazardous characteristics: It is flammable, and its vapor and air can form an explosive mixture. In case of fire, high heat, it will cause fire and explosion. Contact with oxidant reacts violently. Its vapor is heavier than air and can spread to a relatively distant place at a lower place. It will ignite and ignite in case of fire.
Solubility: Slightly soluble in water, soluble in most organic solvents such as ethanol and ether.
Incompatible materials: Strong oxidizing agents, alkalis, acids.
Product advantages
1, can be compatible with most organic solvents
2, has a wide range of solvency, can dissolve acrylic, vinyl, nitrocellulose, epoxy, polyurethane, polyester, phenolic resin, etc.;
3. It has higher flash point and higher anti-whitening performance than acetone, and can better meet the requirements of coatings, paint process recipes and users;
4. It can replace the application of ethyl ester, acetone and methyl ethyl ketone in the process formula requiring low boiling point volatile organic solvent;
5. Polyurethane shoe material can replace cyclopentane, chlorofluorocarbon, etc. as an environmentally friendly foaming agent.
6. VOC-Exempt Regulation Status Exempts from restricted conditions and environmentally friendly solvents.
