COMPOSITION AND METHOD FOR PREVENTION OF LEADING EDGE EROSION IN WIND TURBINES

摘要

The present invention thus provides formulations and precursor compositions that can be used for wind turbine leading edge protection. More particularly, two types of formulations and precursor compositions are disclosed:Formulation type A: a formulation comprising a crosslinked polycondensate (A) and optionally one or more additive(s); wherein the polycondensate (A) contains repeating units derived from at least: a dicarboxylic acid (a); a diol (b); and an ethylenically unsaturated diacid (c); wherein the formulation is cured via ethylenically unsaturated diacid (c). The precursor composition to formulation of type A is a composition that can be cured to yield formulation type A.;Formulation type B: a crosslinked polycondensate (B) and optionally one or more additive(s); wherein the polycondensate (B) contains repeating units derived from at least: a dicarboxylic acid (a") and a diol (b"); wherein the formulation is cured via polycondensate (B) chemical end groups and a cross-linking agent. The precursor composition to formulation of type B is a composition that can be cured to yield formulation type B.;The present invention furthermore provides films and sheets, which contain or consist of formulations of type A or B. The present invention also provides various uses of the formulations of the present invention on wind turbine blade leading edges as described hereinbelow.
