Adhesive and sealant dispensing equipment is refilled with compatible cartridges or bulk material to mix, measure, and consistently distribute adhesives and sealants. Caulk gun applicators and accessories dispense caulks and sealants from single tubes and include components to support their performance and maintenance. Two-part applicators and nozzles dispense two-part adhesives that bond materials together. Spray applicators include tips, guns, and tubing that attach to containers with pressurized adhesive or sealant. Hot melt applicators melt adhesives to produce a controlled flow of glue that bonds materials. Dispensing syringes, bottles, and tips help apply adhesives and sealants in controlled and consistent amounts.
