Introduction  \n2. Range of application  \n3. Color  \n4. Coverage  \nALEXIT® BladeRep® Topcoat ALP20 is a coating system that is specifically designed to enhance the performance of existing lightning protection systems on wind blades. The system features an innovative ArcGuide® technology that facilitates the formation of stronger leaders from the receptor, increasing the probability of lightning strikes attaching to the receptor instead of causing damage to the blade.  \nALEXIT® BladeRep® Topcoat ALP20 is a specialized topcoat designed to be applied as the final coating on wind turbine rotor blades. It can be applied to specific areas of the blade in close proximity to the lightning receptor(s), via roller. BladeRep® Topcoat ALP20 has been tested and validated on blades that have lightning receptors and internal down conductors. Applying the product over blades that use expanded metal foil/mesh or carbon fibre in the vicinity of lightning receptors (within 1 meter) is not recommended.  \n721E - light grey (similar to RAL 7035)  \n3256 -traffic red (similar to RAL 3020)  \n\n|  | m²/kg | m²/kit |\n| --- | --- | --- |\n| Theoretical coverage at 100 µm / 4 mil approx. of mixed material | 3.8 | 3.8 |\n\nRecommended dry film thickness: 100 (±20) µm (4 mil) .  \n5.

Application  \nRoller: High quality solvent resistant rollers, foam or short nap fur type.  \nApplication conditions: 15-35 °C (60-95 °F) and 20-85 % relative humidity. The minimum application condition should  \nbe 3 °C (5 °F) above dew point.  \nIf applying the product in conditions which are not listed above, please consult your ALEXIT® BladeRep® representative.  \nFor Professional Use Only Page 1 of 2  \nThe information contained in this data sheet is based on our level of research and development.
