Solvent-based sealants use solvents or crosslinked polymers with wet and dry bonding formulations. They are often easy to apply and provide a layer of protection against contaminants and environmental stressors. Unlike water-based sealants, solvent-based sealants have smaller particles, which can allow for greater penetration onto a material surface. As solvent-based sealants typically contain VOCs, there are regulations around usage and safe handling requirements. Ellsworth Adhesives supplies solvent-based sealants from 3M and Henkel Loctite.
