SPECIAL RECOMMENDATIONS
Special RecommendationsThis product is filled with micro-balloons which must be thoroughly dispersed at the time of use. · The resin must be deaerated (by vacuum exposure) before casting and also briefly after casting. · Recommended cure is 24 hours at room temperature. Post cure at 60°C may be applied to reduce outgassing. · Post cure at 60°C for 24 hours is compulsory when material is used as insert potting. · Temperature range and cure schedule are dependent on the catalyst used. Both 9 and 11 have space approval, and experience in space use. · Different catalysts will also affect other properties.
