Definitions
- the invention relates to the use of special polyols for the production of isocyanate casting resins and coating compositions.
- the polyols to be used according to the invention are obtainable by epoxidized fatty acid esters of monofunctional Cj. 8 alcohols with alcohols having a functionality in the range from 2 to 10. According to the invention, such epoxidized fatty acid esters are used which are based on fatty acid mixtures as the fatty acid component and which essentially have 18 carbon atoms, the oleic acid content of the fatty acid mixtures being at least 80% by weight.
- Casting resins are liquid synthetic resins or those that can be liquefied by moderate heating, which are poured into open molds and harden there. Casting resins also include isocyanate casting resins. According to DIN 55958, this means synthetic resins that are based on aliphatic, cycloaliphatic or aromatic isocyanates and still contain free isocyanate end groups. They can be cured under various conditions.
- a one-component casting resin consists of a polyurethane prepolymer with terminal free or blocked isocyanate groups, which at Cure exposure to moisture, which can be heated to z. B. to accelerate the reaction or to increase the strength.
- a two-component casting resin is based, for example, on polyhydroxy compounds of branched polyesters or polyethers as the first component and on polyisocyanates as the second component. After mixing both components, they harden at room temperature or slightly elevated temperature. Such two-component casting resins are used, for example, for the casting of cable fittings.
- isocyanate casting resins or coating compositions which are largely insensitive to moisture and chemicals can be prepared by using ring-opening and transesterification products of epoxidized fatty acid esters of monofunctional C ⁇ _ 8 as polyols - uses alcohols. These products are accessible by reacting the epoxidized fatty acid esters with alcohols with a functionality which is preferably in the range from 2 to 4. According to the preparation examples 1 to 5 of the DE-A-43 08 097 mentioned, a technical quality epoxystearic acid methyl ester is used as the starting material.
- fatty acid component on which the methyl epoxystearate is based is a mixture of essentially palmitic acid, stearic acid, oleic acid and linoleic acid, the proportion of oleic acid, based on the total fatty acid mixture, at approx.
- a fatty acid mixture has long been commercially available under the name Edenor TiO5 (manufacturer: Henkel KGaA).
- the polyols according to DE-A-43 08 097 now have a number of application-related advantages, but are generally liquids which are slightly yellow in color.
- the yellow color of these products is unproblematic Applications in the field of casting resins, topcoats or coatings, provided the polyols are reacted with aromatic diisocyanates.

- the R group represents a Cj.g-alkyl group.
- the special fatty alkyl radical i.e. the fat component of the fatty acid ester
- a fatty acid mixture which essentially has 18 carbon atoms and the content of which Fatty acid mixtures Oleic acid - based on the total fatty acid mixture - is at least 80% by weight
- this transformation also applies analogously to the second formula of Scheme 1, whereby this time, of course, not an fatty alkyl residue but an epoxy-fatty alkyl residue is to be replaced, one would get one general scheme which describes the preparation of the polyols according to the invention.
- the present invention therefore relates to the use of polyols which are obtainable by reacting epoxidized fatty acid esters of monofunctional Cj.g alcohols with aliphatic alcohols having a functionality in the range from 2 to 10, the epoxidized fatty acid esters as the fatty acid component being based essentially on fatty acid mixtures 18 C atoms and the content of these fatty acid mixtures of oleic acid - based on the total fatty acid mixture - is at least 80 wt .-% for the production of isocyanate casting resins and coating compositions.
- epoxidized fatty acid esters are reacted with aliphatic alcohols with a functionality in the range from 2 to 10.
- This implementation takes place according to the teaching of DE-A-43 08 097 in the sense of a ring opening and transesterification.

Products of this type can be produced by known processes, and the transesterification can be carried out during or after the ring opening step by removing the lower alcohol from the reaction equilibrium.
- Ring opening and transesterification products are preferred in which a ratio between epoxidized fatty acid ester and the alcohol used for the reaction of 1: 1 to 1:10 is used.
- Analogous to the opening products of epoxidized fatty alcohols, 1: 1 or 1: 2 adducts can also be produced here.
- fatty acid mixtures from new sunflower oil are used as the basis of the epoxidized fatty acid esters as the fatty acid component.
- the fatty acid composition of new sunflower oil is as follows: 80 to 95% by weight oleic acid, 2 to 12% linoleic acid, 1 to 5% stearic acid, 2 to 5% palmitic acid. All percentages are to be understood as% by weight based on the total fatty acid mixture.
- those epoxidized fatty acid esters are particularly preferred which are based on fatty acid mixtures from new sunflower oil as the fatty acid component and in which the oleic acid content of these fatty acid mixtures is at least 85% by weight.
- Such oil is commercially available for example under the name "trisun ®" by the company Special Vegetable Oils (SVO), Eastlake, Ohio, USA.
- a so-called “high-oleic, low stearic” sunflower oil - abbreviated as HOLS sunflower oil - is used as the basis of the epoxidized fatty acid esters.
- the fatty acid composition of HOLS sunflower oil is as follows: 85 to 95% oleic acid, 2 to 8% linoleic acid, 0.5 to 2.5% stearic acid and 2 to 5% palmitic acid ..
