USE OF KETAL AS A SOLVENT IN ADHESIVES AND KETAL-CONTAINING ADHESIVE COMPOSITION

摘要

The present invention relates to the use of a cyclic ketal, 2-methyl-2-ethyl-1,3-dioxolane, as a solvent in adhesives, and to an adhesive composition containing said ketal. The ketal 2-methyl-2-ethyl-1,3-dioxolane exhibits a high solubilising power for the polymer polychloroprene, forming solutions with high viscosity and suitable drying time after application as a film to a surface. Due to its satisfactory technical performance, the adhesive composition with the formulation according to the invention has good market acceptance and can be used instead of compositions containing toluene or other aromatic and oxygenated solvents.
