What is the difference between sealant and silicone?

Due to the low surface energy of cured silicones, it is almost impossible to get anything to easily stick to silicone. Because of this special glues and surface preparations are needed to bond cured silicones to another material. Sealant is a compound used to seal things. Silicone sealant is only one type of sealant.

What is the difference between polyurethane and polysulfide?

Polysulfide is the slowest curing of the three sealant types, often taking a week or more to reach full cure. Polyurethane is the best sealant for the hull-to-deck joint. It is also a good choice for through-hull fittings and for rubrails and toerails, but not if rails are raw teak because some teak cleaners soften it.

Is polysulfide a plastic?

Polysulfide is the most versatile of marine sealants. It is a synthetic rubber with excellent adhesive characteristics, and you can use it for almost everything. However, the solvents in polysulfide sealant attack some plastics, causing them to harden and split.

What is the difference between Sikaflex 512 and Sikaflex EBT?

512 is supposed to be slightly faster curing, with better resistance to UV. EBT may cure faster in moist conditions. I think any of them will be very good, providing the surfaces to be bonded are well degreased (meths). Just don’t use it if you want to take it apart again!
