A polyol emulsion of castor oil and monoepoxides is combined with methylenediphenyl diisocyanate (MDI) and cement to produce a polymer cement.

Castor oil-based polyol emulsions

A process for preparing hydrophobic polyols that includes reacting A) a mixture having an OH content of from 180 to 300 mg KOH/g, a viscosity at 23&#xb0; C. of from 5000 to 20 000 mPas and an OH functionality of from 2.8 to 4.5 including from 5 to 20 wt. % of 3-pentadecadienylphenol, from 5 to 10 wt. % of 3-pentadecadienyl-recorcinol and from 1 to 5 wt. % of 2-methyl 3-pentadecadienylrecorcinol; with B) alkylene oxides (AO) with addition of the AO monomers onto the AO-reactive groups of component A); the ratio of the amounts of A) to B) being from 1:9 to 9:1; where the hydrophobic polyols have an OH number of from 140 to 220 mg KOH/g and a viscosity at 23&#xb0; C. of from 1000 to 4000 mPas. The hydrophobic polyols can be used in polyurethane systems, in coatings, adhesive bonds, sealants or moulding compounds, which can be used to coat substrates.
