	SPECIAL RECOMMENDATIONS

Special Recommendations

Recommended cure: 15 mins. at 125°C after last layer + post cure 50 Hours at 100°C (Specification ECSS-Q-70-34). · Primer: Lesonol 01-66050 may be used for increased adhesion. · 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 according to ECSS-Q-70-02 are recommended. · Difficult to procure in Europe.
