| Résumé : |
The authors explain why the use of hydrophobic polyols can achieve better surface performance in coating and flooring applications.
Oleochemical polyols are spacial polyfunctional alcohols based on natural vegetable oils. They offer alternatives to higher hydrophilicity petrochemical-based polyols.
Because they are derivatives of vegetable triglyceride oils, they retain the advantages of classical oil paints and alkyd resins. But because of their low viscosity, they offer a base for solvent-free, full solids coating systems. As so-called reactive diluents, they are additionally able to replace solvents in coatings by forming part of the polymer film after curing instead of evaporating as solvent do. |
