FIELD: polymer materials. ^ SUBSTANCE: invention relates to polyurethane-polyol compositions comprising product of reaction of a polyol and Herbert alcohol, the two containing In average 12 carbon atoms. Preferred polyols are alpha,beta-diols and alpha,beta-diols. Polyurethane-polyol compositions exhibit very low viscosity and are particularly suitable in coating compositions with very low content of volatile organics. Hardened coating obtained from claimed compositions ensure high resistance to cracking and can be applied on various substrates such as metal, plastic, wood, glass, ceramics. ^ EFFECT: increased strength of coatings on a variety of substrates. ^ 5 cl, 3 tbl |
