ANTI-ADHESION COMPOSITION Russian patent published in 2006 - IPC B05D5/08 

FIELD: anti-adhesion materials.

SUBSTANCE: invention relates to a composition comprising 0.1-4% of mixture of perfluoropolyoxaalkylene carboxylic acids of the general formula: wherein n = 3-50. For preparing colloidal solution of perfluoropolyoxaalkylene acid the composition comprises additionally 1-2% of amidoalcohol of the general formula: wherein n = 0 or 1; m = 1 at q = 1 and m = 2 at q = 0 that is prepared by interaction of dimer and/or trimer of hexafluoropropylene oxide with mono- and/or diethanolamine and water, up to 100. After treatment with the proposed composition surface of solid bodies acquires water-oil-repelling properties and the gluing seam rupture strength is reduced by two orders that accords with strength levels providing by the nearest analog representing a mixture of perfluoropolyoxaalkylene acids in coolants. Invention can be used for decreasing adherence of moldable plastic, crude rubber articles and other polymers to a tool and press-forms.

EFFECT: improved and valuable technical properties of composition.
