Solvent based silane sealer Stifel 40/40 LVOC is a transparent, breathable, ready-to-use formula that penetrates deep into concrete and masonry. Stifel 40 has a small molecular structure that allows it to move through concrete pores and penetrate deep, up to 1/2-inch or more. It chemically reacts with siliceous materials to form a hydrophobic barrier to prevent the absorption of water and waterborne chloride ions. In effect, users will experience a long-lasting water-repellent surface.

Applications

• Use on concrete parking garages, driveways, parking lots, sidewalks, bridge decks, pool decks, patios, vertical concrete, masonry and more.

• Protects reinforcing steel in concrete from corrosion due to the effects of water, deicing salts and other water borne chemicals.

• Suitable for use on smooth concrete or exposed aggregate.

• Suitable in precast, prestressed, and poured-in-place applications.

• In lightweight and air entrained concrete.

Advantages of this Solvent Based Silane Sealer

• Silane penetrates deep into substrate in order to achieve a high level of water and chloride screening.

• Protects against the damaging effects of water intrusion, deicing chemicals and also exposure to freeze/thaw conditions.

• Contains 51% active silane to penetrate deep into the capillaries of the substrate without producing a film.

• Breathable to allow interior moisture to escape without damaging sealer.

• Colorless, non-staining, non-yellowing - does not alter the natural appearance of concrete's surface.

• Protects without altering the appearance or texture of the treated surface.

• Chemical reactions with the capillaries form long-lasting water repellent groups that crosslink to minimize water intrusion.

• As a water repellent, helps to protect from damage caused by chloride ion intrusion in order to extend the life of the treated surfaces.

• Leaves no residue on non-porous surfaces such as glass, metal frames or painted surfaces.
