What's the difference between water-based mastic and solvent-based duct sealant?

Water-Based Mastic (e.g., DP-1010): Low odor, cleans up easily with soap and water, non-flammable. This is the daily standard for indoor commercial duct sealing. Solvent-Based Sealant: Highly flammable, strong chemical fumes, handles moisture and extreme temperature swings quickly. Used primarily for outdoor roof applications or wet industrial environments.
