AkzoNobel AEROWAVE-2501 (290-ml)

Additional Product Information

Overview

Aerowave Filler 2501 is a high-performance, low-VOC, two-component filler designed for aerospace composite, plastic, and metallic substrates. It enables fast curing at ambient conditions, remains flexible after curing, and provides a shrinkage-free surface. Aviation and MRO teams rely on it for precision surface repairs, filler applications, and preparing substrates for primer and topcoat processes. Its low dry-film-weight and efficient application reduce operational costs while maintaining environmental compliance.
