Adhesives connect materials with a higher strength but are not always elastic and don't allow much movement between the surfaces. Sealants connect materials, sealing the gap in-between surfaces to block out any dust and debris, they can also absorb the movements within the joint and provide a more finished look to a project. Sealants tend to make a weaker connection between two surfaces. Some hybrid products such a Fix ALL offer both a strong connection and a perfect seal. The hybrid technology combines both properties of a sealant and an adhesive.
