The invention relates to adhesive compositions containing alcohol and isocyanate components, antipyren, pigment and filler. It contains carbofunctional boron-containing oligoalcohols with molecular mass of from 120 to 420 and hydroxyl groups’content of from 12.5 to 34.0 wt. % that are prepared by azeotropic etherification of boric acide with individual acyclic diols at a ratio of from 1:2 to 1:3 (in moles), and in addition it contains a solvent up to required consistency. Samples of adhesive compounds based on such a composition exhibits tensile at break within the range of 2.7 ÷ 5.9 Mpa against 2.52 Mpa in the best sample of prototype. |
