The present invention is directed to a composition for stripping coatings from a surface, the composition including: a. A solvent mixture composed of a phenyl substituted alkyl alcohol and an alkyl or aryl glycol ether or an alkyl or aromatic alcohol; b. A coupler composed of a salt formed from a water soluble organic amine and an acid comprising at least one C7-C18 ethoxylated anionic surfactant; c. Optionally water. The use of the C7-C18 ethoxylated anionic surfactant provides a stripper which can be diluted in water of various compositions yet provides an effective stripping/cleaning agent.
La présente invention concerne une composition permettant de décaper des revêtement d'une surface, cette composition comprenant: a. Un mélange de solvants formé d'un alcool d'alkyle à substitution phényle et d'un éther d'aryle glycol ou d'alkyle ou d'un alkyle ou encore d'un alcool aromatique; b. Un agent de couplage constitué d'un sel formé à partir d'une amine organique soluble dans l'eau et d'un acide comprenant au moins un tensioactif anionique éthoxylé C7-C18; c. Facultativement de l'eau. L'utilisation du tensioactif anionique éthoxylé C7-C18 permet d'obtenir un décapant qui peut être dilué dans l'eau de diverses compositions et qui constitue cependant un agent décapant/nettoyant efficace.
