SPECIAL RECOMMENDATIONS
Special RecommendationsRecommended proportions: 100 pbw part A, 0.2 pbw part B. Thorough mixing is necessary. · Cure 7 days at room temperature. · For superior adhesion, use primer DC 1200 (Dow Corning) or SS 4155 (General Electric). · Can be made electrically conductive with Cho-Bond 1029B: 250 pbw for 100 pbw RTV 566. · RTV 567, a nonfilled version of 566, is very difficult to procure in Europe.
