  • Formwork release composition and use thereof
    Patent number: 8709534
    Abstract: A formwork release composition containing formwork release oil, which contains a hydrophobic metal oxide and/or metal sulphide component is disclosed. Photocatalytically active compounds, such as particular semiconductors and in particular TiO2, are particularly suitable. The invention also concerns the use of the formwork release composition for producing exposed concrete. The concrete and mortar products thus produced are characterized by a homogeneous surface with self-cleaning properties that gives an enhanced resistance against weathering and a much longer lasting brilliance and whiteness.
    Type: Grant
