CONCRETE FORM RELEASE COMPOSITIONS

摘要

The forming of shapes using cement and/or concrete is an old art. In this process a form is removed, leaving the shape of the pattern which is result of the form designed. Fluid concrete and/or cement can then be poured into the cavity to form the object . To increase the life of the forms, and to make removal of the form easier, the form must be coate d with a protective material. Despite many available form release compounds, mineral seal oil, a nd a mixture of mineral seal and oleic acid, have been the commercial choices. A biodegradab le form release composition including vegetable oil with a petroleum oil and/or an alcohol a nd a method of utilizing such a release composition to reduce adhesion between concrete and formwork or a mold is disclosed. The form release composition is biodegradable with a low VOC content.
