Architects, engineers and contractors select stone and tile to add function and decoration to structures. Whether it is for commercial or residential construction projects, these elements must be applied with liquid and oil repellents to maintain their appearance and value. That’s why AGC developed AsahiGuard® for Stone and Tile to preserve porous and non-porous stone and tile.
From Marble to Terra Cotta, Inside and Out
AsahiGuard is effective for polished stones (marble and granite), porous stones (limestone) and very porous materials (concrete, terra cotta, brick and paving stones). Professionals use AsahiGuard to protect countertops, shower stalls, flooring, patios, walkways, walls, hearths, backsplashes, fireplaces and pool aprons. AsahiGuard liquid and oil repellents significantly minimizes staining of stone by common fluids like red wine, coffee, mustard, ketchup, blue ink, mayonnaise, soda, suntan lotion, motor oil and olive oil.
AsahiGuard uses fluoropolymers dispersed in water to repel liquids by forming a low-energy surface coating on treated stone. Liquids bead when spilled on stone or tile treated with AsahiGuard sealants. This beading action minimizes the amount of surface area that the spilled fluid contacts, neutralizes penetration and enhances cleanability. AsahiGuard products require just one application added in the factory or field either by brush or roller, and they cure quickly at air temperature and are odor-free.
Because it is based on short-chain C6 chemistry, AsahiGuard imposes no danger to humans, animals, materials or the environment. C6 fluorinated polymers are proven safe for use on stone and tile, contain no perfluorooctanoic acid (PFOA) or perfluorooctane sulfonic acid (PFOS) or their precursors, at detectable limits, and cannot break down to form PFOA or PFOS.
AsahiGuard is formalin-free, non-flammable and non-corrosive. It meets the most stringent regulatory requirements internationally, including the U.S. Toxic Substance Control Act, Japan’s Chemical Substances Control Law, and all applicable European Union standards.
AsahiGuard formulation depends on the type of stone or tile and indoor or outdoor use. Custom formulations provide additional aesthetic characteristics such as high gloss, low gloss, enhanced color or a wet look.
To ensure that customers receive just the right sealing solution for their projects, AGC’s technology service experts provide testing including: Oil/water repellency; stain resistance; cleanability; formulation recommendation and development; and on-site support for product trials.
