UV Curing Composite Technology
Open the catalog to page 1RENUVO Guru RENUVO™ offers a fresh and novel approach to the manufacture, maintenance and repair of today's wind turbine blades. RENUVO™ uses UV light from specially-designed lamp equipment to achieve full cure in justa few minutes. RENUVO™ Blade Repair RENUVO™ blade repair materials are designed to be handled at temperatures as low as +5°C. This greatly widens the operating window for carrying out repairs and dramatically reduces the turbine downtime. RENUVO™ materials are easy to handle, requiring no mixing or awkward hand-impregnation of heavy glass fabrics. The RENUVO™ product range...
Open the catalog to page 2RENUVO™ In-Factory Blade Production and Finishing RENUVO™ materials are also suited to the automation and optimisation of existing in-factory blade production processes such as leading and trailing edge finishing, in-mould repairs and surface preparation prior to topcoat applications. As blade production processes can vary greatly, any of the RENUVO™ products may be combined in order to achieve a bespoke solution. In order to maximise the flexibility of such solutions, RENUVO™ Wet Laminating (WL) has been developed specifically for in-factory applications: RENUVO™ WL: Formulated to behave...
