Morphology

sealant = seal (transparent) = seal + ant

The noun denotes a substance that seals; straightforward derivation from the verb 'seal' with the productive suffix '-ant'.

Etymology

The word sealant starts with the simple verb seal, which means 'to close' or 'make tight', and adds the ending -ant, which makes a noun meaning 'a thing that does the action'. So a sealant is a material that 'closes' gaps to stop water or air.
