Blue Dichtol Polymeric Capillary Sealer

Stronghold Coatings introduces Blue Dichtol, a polymeric capillary sealer for castings and composites that allows 100 percent visual inspection to ensure that porosity has been sealed. It impregnates micropores and hairline cracks without vacuum or pressure, forming a protective barrier to gasses and liquids that is not invisible when cured. 

Blue Dichtol penetrates deeply, (up to 0.004”), into the coating to prevent corrosion of the metal substrate. Pressure resistant to 8,700 psi, and temperature resistant to 932° F, this product is ideal for castings, composites and more. Easily applied by dip, brush or spray, it dries in minutes and cures at ambient temperature. It significantly increases machinability and dampens vibration, to further enhance the utility of the components being treated. Proven in a wide range of industries and applications including sealing of engine casings, pump housings, bridge cables, composite parts, and all thermal sprayed coatings.

Approved for military use, NSN8010016541508, and made in the USA, Blue Dichtol is part of the Dichtol family of capillary sealers that offer an economical alternative to pressure or vacuum impregnation of castings. Dichtol-treated castings had a significantly lower failure rate compared to vacuum impregnation on the same parts.
