SPECIAL RECOMMENDATIONS
Special RecommendationsRecommended cure is 24 hours at room temperature, plus 4 hours at 60°C with catalyst 9. · Other catalysts are available for the same resin, but these will affect the properties: Catalyst 11 for high-temperature cure; Catalyst 24 LV for low viscosity. Some experience in space is available for both. · A derived resin (2850 KT) can be used for extremely high thermal conductance (4.2 W/m.K).
