The composition comprises a polyurethane polymer having cycloaliphatic isocyanate group, and a cycloaliphatic dialdimine of general formula (I). 10-70 %, preferably 20-60 wt.% of a filler is also provided. The polyurethane polymer is made of polyol and a cycloaliphatic diisocyanate. The cycloaliphatic dialdimine having general formula (I). R 1>, R 2>univalent or bivalent hydrocarbon residue, preferably a methyl group; R 3>H or 1-12C alkyl or arylalkyl group; R 4>heteroatom, hydrocarbon residue or a residue of general formula (II), where R 5>=6-30C linear or branched alkyl residue with oxygen in the form of ether, ester or aldehyde or 5-6 membered aromatic or heteroaromatic ring; A : cycloaliphatic primary diamine residue after removal of two primary amino groups; and n : 2. (A) Provided that the cycloaliphatic primary diamine residue does not have hydroxyl group, primary or secondary amino group, mercapto group, urea and other groups having active hydrogen. Independent claims are included for: (1) a method for adhesion of substrates, which involves applying composition; and (2) a method for producing a coating, which involves applying composition on substrate.
