Organic solvents used to prepare diluents

The previous article introduced the function and dosage of thinner,Click to read: The role and dosage of diluent, below, we introduce which organic solvents can be used to prepare dilutions agent.

The composition of the thinner is not a technical secret, because the corresponding composition is found in the MSDS that the coating manufacturer must provide or disclose (although the composition of the composition in the MSDS usually gives a range).

Let’s look at the commonly used ones first What are the organic solvents used to prepare non-reactive diluents?

①Aliphatic hydrocarbons: Carbon atoms in the molecule are linked into chains Carbon skeleton, hydrocarbons that are open at both ends without forming a ring are called open-chain hydrocarbons, or chain hydrocarbons for short. Because fats have this structure, they are also called aliphatic hydrocarbons. Commonly used aliphatic hydrocarbon solvents include 200# solvent gasoline (rosin water, mineral spirits, white water), 140# solvent gasoline, etc.

② Aromatic hydrocarbons: Aromatic hydrocarbons usually refer to hydrocarbons containing benzene ring structures in their molecules. It is a type of closed chain. It has the basic structure of a benzene ring. Most of the compounds discovered early in history had an aromatic taste, so these hydrocarbons were called aromatic hydrocarbons. Hydrocarbons discovered later that did not have an aromatic taste also used this name. Aromatic hydrocarbon solvents include: benzene, toluene, xylene (usually a mixture of isomers including ethylbenzene), trimethylbenzene (usually a mixture of isomers), heavy aromatic hydrocarbon solvent naphtha (also known as high Boiling point aromatic hydrocarbon solvents refer to aromatic hydrocarbon mixtures with more than 10 carbon atoms).

③Alcohols: including methanol, ethanol, isopropyl alcohol, n-butanol, benzyl alcohol, etc.

④Esters, alcohol esters : Ethyl acetate, butyl acetate, sec-butyl acetate, propylene glycol methyl ether acetate (PMA), propylene glycol ethyl ether acetate, ethylene glycol Diethyl ether acetate, ethylene glycol butyl ether acetate, dimethyl carbonate, mixed dibasic acid ester (DBE), mixed acid propylene glycol ester (CBE), polyol dibasic acid ester (EGDA), etc.

⑤Ketones: acetone, methyl ethyl ketone (butanone), cyclohexanone, methyl isobutyl ketone (MIBK), isophorone, diacetone alcohol, etc.

⑥Alcohol ethers
