- the polyurethanes according to the invention have a thickening power and develop the desired thickening at low speed gradient.
- This example illustrates the medium shear gradient viscosity (Stormer TM in KU), stretched-out and sag resistance of said paint formulation using a polyurethane according to the invention (tests 2-3 and 2-4), using a compound of formula (I) comprising 8 or 10 ethylene oxide units.
- this example also illustrates a polyurethane of the Acrysol RM825 type (test 2-1, commercial product of reference in the field of paints) and two polyurethanes according to the patent application WO 02/102868 (tests 2-2 and 2-5). , using a compound comprising respectively 3 and 25 ethylene oxide units.
- Test 2-1 (Without Invention - Acrysol RM825)
- Test 2-2 (Without Invention - 3 ethylene oxide units)
- Tests 2-3 and 2-4 (according to the invention - respectively 8 and 10 units of ethylene oxide) Allow to obtain a formulation having a good compromise thickening / stretched-spreading / resistance to sagging.
