How to apply
Apply a bead of Besil 93 series Adhesive/Sealant (see Handling Precautions) to one of the prepared surfaces, then quickly cover with the other substrate to be bonded.
On exposure to moisture, the freshly applied material will “skin-over” in about 2-5 minutes at room temperature and 50% relative humidity. Any tooling should be completed before this skin forms. The surface is easily tooled with a spatula. The adhesive/sealant will be tack-free in approximately 5 minutes.
Cure time
After skin cured continues inward from the surface. In 24 hours (at room temperature and 50% relative humidity) Besil 93 series Adhesive/Sealant will cure to a depthof about 2mm. Very deep 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
