SPECIAL RECOMMENDATIONS
· Recommended cure: 16 HoursHH at 65°C after last layer of paint has been applied ECSS-Q-70-35. · 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). · Quality control tests by micro-VCM (ECSS-Q-70-02) are recommended. · Flammability test on 1mm thick Aluminium substrate in 21% O₂. Material burns when applied to 7.6 micron Kapton. Configuration test mandatory. · Use with Pyrolac P123 Primer for better adhesion. · Difficult to procure in Europe.
