Moisture Resistance and Water Vapor Permeability Testing for Aerogel Insulation Coatings

Water absorption by total immersion per ASTM D570 and ISO 62 — the coated specimen is immersed in water and the mass of water absorbed is measured to verify the aerogel thermal insulation coating resists moisture uptake, which would degrade its insulation performance and promote corrosion of the substrate.
Water vapor transmission rate and permeability per ASTM E96 and ISO 12572 — the moisture vapor permeability of the aerogel coating is measured to confirm the coating allows the substrate to breathe and prevents condensation build-up within the building envelope or insulation system.
