PP U V C u r i n g C o m p o s i t e Te c h n o l o g y Prepreg NEW: UV curing biaxial Prepreg for Turbine Blade repair. Fast curing single component resin developed to work even in low temperatures, saving time, effort and waste in all repair formats. n UV Curing resin system with dedicated RENUVO™ Lamp Technology n Summer grade material for use at +15OC to +30OC n Winter grade material for use at +5OC to +18OC n Compatible with current topcoat solutions n Benefits from SparPreg™ handling characteristics n Clean processing avoiding mixing and contamination n GL Certified product range n Long outlife at room temperature n Excellent Mechanical Properties Introduction RENUVO™ Prepreg (PP) is a breakthrough UV curing Prepreg system, developed by Gurit as a repair system for turbine blades. The system is used in combination with RENUVO™ Multi-Purpose System (MPS) to complete structural repairs. RENUVO™ PP offers a step change in materials for the repair market. With working temperatures as low as +5OC, PP has demonstrated a practical solution to an engineering problem, how to perform repairs, quickly, at these temperatures. For this reason, 2 specific grades of material have been formulated to give the operator the right material for both hot and cold environments. Additionally both grades are available in unidirectional (UD) and biaxial (XE) formats. The RENUVO™ PP system eliminates the human error of mixing, dispensing and working with more traditional wet laminating repair systems. Additionally the material offers the operator the security that wherever the material has been sourced it is the same product manufactured to the same high exacting process. Using a dedicated UV source, ideally RENUVO™ Lamp Technology, RENUVO™ PP is cured in 180 seconds for a leading edge repair, up to 5mm thickness. Used in combination with RENUVO™ MPS, the repair can be quickly finished without the need for secondary operations to fill and fair. PDSWE-RENUVO PP-4-0911 1

Transport & Storage The RENUVO™ Prepreg should be stored in its original packaging during transport and storage. Suitable long-term storage conditions will result in a shelf life of 1 year at 21°C. Storage should be in a dry place out of direct sunlight and ambient light, since the prepreg is sensitive to UV light. The recommended storage temperature should be between -18°C and 21°C. Whilst storage at higher temperatures between +5°C and 30°C prior to application will not adversely affect the product shelf-life, it may cause problems such as distortions of the prepreg and excess resin bleed....
