The Physical property above was test after cured 7 days. Shear test of base material is iron tablets
In 24 hours (at room temperature and 50% relative humidity) SATOP® 8576 Adhesive/Sealant will cure to a depth of about 2-3mm. If deeper sections, especially when access to atmospheric moisture is restricted, will take longer to cure completely.
Cure time is extended at lower humidity levels. Before handling and packaging bonded components, users are advised to wait a sufficiently long time to ensure that the integrity of the adhesive seal is not affected. This will depend on many factors and should be determined by the user for each specific application.
To reach stable property, it’s better to rise the temperature step by step, for example, after cured 7 days, heat the sealant on 150℃ for 5 hours, then 200℃ for 4hours, 230℃ for 4hours, 250℃ for 3 hours ,and 280℃ for 2hours.
