chemical industry. SUBSTANCE: described is polyethylene-based composition wherein polyethylene is multimodal and is essentially mixture of at least first polyethylene having first average molecular weight corresponding to fluidity melt from 50 g/10 min to 2000 g/10 min and with first molecular weight-distribution, and second polyethylene with second average molecular weight which exceeds said first average molecular weight, and with second molecular weight distribution, ratio between first and second polyethylenes varying from 20:80-80:20, and said mixture has third average molecular weight corresponding to fluidity of melt from 0.1 g/10 min to 50 g/10 min, and third molecular weight distribution corresponding to ratio of fluidity of melt ( ell known coating compositions have insufficient coating ability and unsatisfactory resistance to cracking from outside load. EFFECT: claimed coating composition has good said parameters. 36 cl, 3 ex, 4 tbl |
