AkzoNobel AEROBASE-G90004 (5-LITRE-CAN)

Aerobase Polyurethane Top Coat

Overview

Aerobase is a low VOC, isocyanate-cured, three-component polyurethane basecoat developed by AkzoNobel Aerospace Coatings for commercial aircraft exterior finishing. Designed for use within a basecoat/clearcoat system, Aerobase delivers exceptional colour uniformity, gloss retention and long-term weatherability while reducing process time through rapid drying. When combined with approved Aviox® Clearcoat UVR, the system provides a durable, high-gloss finish that meets and exceeds OEM requirements for exterior aircraft performance.
