SPECIAL RECOMMENDATIONS
Special RecommendationsRecommended cures: 7 days at room temperature, or 24 hours at 70°C. · Compositions other than the one detailed here are possible. Large amounts of experimental data on them exists and is available on demand. · Not resistant to solar UV radiation. · Owing to flammability risk, not to be used as a conformal coating in manned spacecraft unless a fire-resistant overcoating is used. It’s acceptability as an adhesive will depend on the configuration. · Possible use as a screw-locking compound. · Possible use as an ink with suitable addition of pigments and solvents. · Possible use as a conductive coating when filled with silver powder. · Flammability highly dependent on coating thickness. Configuration flammability tests required.
