SPECIAL RECOMMENDATIONS
Special RecommendationsThe accelerator (catalyst) is sensitive to atmospheric humidity and CO2. Minimal exposure to atmosphere is recommended during storage and mixing. · Recommended cure is 2 hours at 70°C. · Quality control test by micro-VCM method (ECSS-Q-ST-70-02C) is recommended.
