SPECIAL RECOMMENDATIONS
· Cuvertin 306 made by Henkel (Germany) generally shows higher TML/CVCM. · This paint (like most others) is not recommended for use in badly vented places where high electrical fields are present in the vicinity (corona risk). · Coating to be applied according to ECSS-Q-70-25 with use of Pyrolac P123 Primer. · Quality control tests by micro-VCM (ECSS-Q-70-02) are recommended. · Flammability test on 1mm thick Aluminium substrate in 24.5% O2. Material burns when applied to other substrates, e.g. Kapton. Configuration test mandatory. · This paint has been shown to contaminate space hardware returned from space. This is probably due to processing aids based on silicones.
