Abstract
The present invention relates to the use of a cyclic ketal, 2-methyl-2-ethyl-1,3-dioxolane as a solvent in adhesives, as well as an adhesive composition comprising said ketal. 2-Methyl-2-ethyl-1,3-dioxolane has high solubilization power of the polychloroprene polymer, forming solutions having high viscosity and having suitable drying time after application of a film onto a surface. Due to the good technical performance, the adhesive composition made according to the present invention is well accepted in the market, finding use to substitute compositions containing toluene or other aromatic and oxygenated solvents.
