FIELD: materials.
SUBSTANCE: invention relates to glueing compositions for fiberglass strands, the fiberglass strands obtained by coating glass fibres with the said glueing compositions and composite materials containing the said fiberglass strands. Glueing composition contains by weight of dry residue/content of dry substance: 0.1-2 % of at least one structurising additive, 2-15 % of at least one film-forming agent, 0.1-4 % of at least one binding agent, 0.01-0.5 % of at least one cationic polymer containing a poly-alkylen imine skeleton, wherein the said polymer has 20 % or less of active amino groups, 0.1-6 % of at least one compound selected from a lubricant, a surfactant, a plasticizer, a dispersing agent, additives and their mixtures.
EFFECT: technical result is improvement of stability and the increase of viscosity of the glueing composition while improving treatment of fibres.
