Abstract
An aqueous fire-retardant composition capable of forming a foam layer and consisting of I. an aqueous preparation comprising A. a non-etherified amino-formaldehyde resin or its components or a mixture thereof B. at least one ammonium phosphate, C. a skeleton forming component and Ii. a solution of at least one further amino-formaldehyde resin being at least partially etherified with at least one alcohol having 1 to 12 C-atoms and dissolved in an organic solvent, a construction supporting unit and an electrical cable unit with a coating of said composition.

An aqueous fire-retardant coating composition capable of forming a foam layer and consisting of
- I. an aqueous preparation comprising
- a. a non-etherified amino-formaldehyde resin or its components or a mixture thereof
- b. at least one ammonium phosphate,
- c. a skeleton-forming component and
- Ii. a solution of at least one further amino-formaldehyde resin being at least partially etherified with at least one alcohol having 1 to 12 C-atoms and dissolved in an organic solvent.
In a heat-foamable fire-retardant composition having a) a skeleton-forming component and b) at least one ammonium phosphate component, the combination of c) an aqueous phase with non-etherified amino-formaldehyde resin or components thereof and d) an organic-solvent solution of amino-formaldehyde resin at least partially etherified with alcohol having from 1 to 12 carbon atoms;
- the amino-formaldehyde resin which is at least partially etherified being other than a resin based on dicyanodiamide when the non-etherified amino-formaldehyde resin of (c) is based on dicyanodiamide.
