FIELD: machine building.
SUBSTANCE: fibre-optic structure covered with resin composition, at that resin composition contains the following components in specified proportions expressed in weight percentage of solid substance: 75 - 98% of mixture of at least one novolak with glass-transition temperature below or equal to 60°C and of at least one novolak with glass-transition temperature above 60°C, 0.5 - 10% of at least one wax, 0 - 3.5% of at least one plasticising agent.
EFFECT: producing resin composition proper for coverage of fibre-optic structure meant for strengthening of abrasives in a bunch which confers the structure more elasticity and low adhesiveness, reduces risk of contaminating release of formaldehyde and nitrogen compounds.
