Henkel Aerospace has developed a new chemistry platform for composite structural applications. The objectives were to develop a broad base resin technology with superior process characteristics and higher thermal and mechanical performance to bridge the gap between 140°C hot/wet T{sub}g epoxy performance and 220°C hot/wet T{sub}g BMI performance. Because of its ambient stability, this one part resin system is easy to handle, store and transport. Low viscosity and long pot life at process temperature offer robustness in advanced processes. This resin system shows superior cure shrinkage and high compression strength and modulus. Additionally, this 120°C-180°C cure resin system gives a very good combination of hot/wet T{sub}g, toughness and modulus. The combination of processing ease, excellent mechanical properties and very low cure shrinkage provides more cost effective composite parts with reduced weight and lower service operation costs. This paper reviews the application of this system as a matrix resin for prepreg, other advanced composites and syntactics.
