Butyl Lactate

Butyl lactate is a butyl ester derivative of lactic acid produced by fermentation of carbohydrates as raw materials. Since butyl-L-lactate is an environmentally friendly high boiling point solvent, it is widely used in paints, coatings, plastics, and other fields.

Characteristics

The use of green solvents instead of traditional solvents has been the development trend of coating and ink and other related industries. Characteristics of butyl-L-lactate as a green solvent include:

It is made from plant-based raw materials, which is renewable.
It can be biodegraded to carbon dioxide and water, which is environmentally friendly.
It has natural aromatic fragrance and low volatility, which effectively improves the strong irritating odor of traditional solvents.
With good miscibility with organic compounds.
It has good viscosity, effectively improves the strength of the coating, and can improve the gloss of the coating.
It can solve the problem of gloss loss and shrinkage in coatings (e.g. anti corrosive coating) for its high boiling point and low volatility.
