Laminating resin system approved by the GERMAN FEDERAL AVIATION AUTHORITY with different pot lives for processing of glass, carbon and aramide fibres, featuring high static and dynamic loadability.
After heat treatment at 50 – 55 °C (120-130°F), the system meets the standards for gliders and motor gliders
(operational temperatures -60°C (-75°F) to +54°C (130°F)). In order to meet the standards for motor planes
(operational temperatures -60°C (-75°F) to + 72°C (160°F), heat treatment at 80 °C (175°F) is necessary.
The range of pot lives is between approx. 45 min and 5 h. The hardeners have the same mixing ratio and can be mixed among themselves in any ratio. This permits a selection of the optimum system for all processing methods.
After initial curing at room temperature, the components manufactured are workable and demouldable.
You will receive high-gloss and non-tacky surfaces, even with unfavourable precuring conditions, e. g. lower temperatures or high humidities.
The mixing viscosity guarantees fast and complete impregnation of the reinforcement fibres; however, the resin will not spill out of the fabrics on vertical surfaces. In order to obtain special properties, it is also possible to add fillers to the mixture of resin/hardener, such as Aero-sil, microballoons, cotton flakes, metal powder, etc.
If high heat resistance or aircraft approval are not necessary, hardener 285 can also be used without heat treatment afterwards. However, the indicated properties will only be obtained after heat treatment at temperatures over 50°C (120°F).
