After more than a year-long testing with selected customers, we have officially launched the softer version of our well recognized visual epoxy system EP4.5 – the EP4.5S. The resin system keeps the key features of standard EP4.5, such as excellent surface part quality with a standard autoclave process. On top it is very soft and with perfect drapability. The prepreg with EP4.5S resin matrix is thus especially suitable for easy layup of complex parts and can improve the clean room efficiency due to faster layup process.
