Self-amalgamating tape is very similar to silicone tape, because it bonds to itself when it is stretched. It doesn’t contain any adhesive or gum to create a seal like most tapes. It is made of ethylene propylene rubber and needs to be lapped over itself to work.
3. Peel and stick.Butyl sealant tape usually comes with a protective backing to prevent it from sticking to itself during storage and handling. Carefully peel off the backing to expose the adhesive side of the tape. Position the adhesive side of the tape on the surface, and carefully align it with the area to be sealed.
Wrap and Stretch: Begin wrapping the tape around the object or area that needs repair. Stretch it slightly as you wrap to activate the self-fusing properties.
