MasterProtect H 1100

Hydrophobic Isobutyltriethoxysilane Liquid for Effective Concrete and Masonry Impregnation

How Does MasterProtect H 1100 Work?

MasterProtect H 1100 is undiluted isobutyltriethoxysilane, a clear, low-viscosity liquid. MasterProtect H 1100 has a very low molecular size, which ensures effective impregnation of concrete and masonry surfaces with 3-8 mm penetration into the pore structure.

The impregnated MasterProtect H 1100 reacts with moisture or interstitial humidity and forms a permanently bonded hydrophobic lining on the pore walls of the substrate.MasterProtect H 1100 does not change the appearance of the base concrete after absorption and thus is ideal for architectural concrete elements. MasterProtect H 1100 is also available with a red fugitive dye that provides easy identification of the treated areas. The colour of the dye will disappear in approximately 1 week, depending on the number of coats applied and the amount of UV light.

Recommended Uses:

MasterProtect H 1100 is recommended for application to most cementitious, masonry, and mineral substrates above ground, not subject to hydrostatic pressure. Applications include treating the surfaces of:

• Bridge decks, abutments, piers, soffits, etc.

• Beams, columns, and walls of buildings

• Exposed brick structures

• Car parks

• Marine structures

What Are the Unique Features of MasterProtect H 1100?

The treated substrates are highly hydrophobic and will inhibit the ingress of liquid water and waterborne aggressive agents such as chlorides. It also provides a barrier to attack by dissolved carbon dioxide by preventing carbonic acid from entering the structure. MasterProtect H 1100 does not change the appearance of the base concrete after absorption and thus is ideal for architectural concrete elements. MasterProtect H 1100 is also available with a red fugitive dye that provides easy identification of the treated areas.

What Are the Benefits of MasterProtect H 1100?

• Effective water repellence - inhibits ingress of waterborne aggressive agents such as chlorides, giving long-term protection from reinforcing corrosion

• Minimises surface efflorescence - maintains a clean appearance of masonry surfaces

• Breathable - allows water vapour to move through the substrate

• Highly penetrative - ensures long-term effectiveness even on surfaces exposed to traffic (e.g.: car parks)

• Can be supplied with a fugitive dye-treated are easily identifiable, no wasteful repetitive coatings or risk of untreated areas
