MasterProtect H 1100

HYDROPHOBIC IMPREGNANT BASED ON ISOBUTYLTRIETHOXYSILANE

Description

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

Uses

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 an 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.

MasterProtect H 1100 is recommended for application to most of the 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

Advantages

The treated substrates are therefore highly hydrophobic and will inhibit ingress of liquid water and water borne aggressive agents such as chlorides. It also provides a barrier to the attack done by dissolved carbon dioxide by preventing carbonic acid 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 an 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.

Effective water repellence – durability. Inhibits ingress of water borne aggressive agents such as chlorides giving long term protection from reinforcing corrosion

Minimises surface efflorescence – 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 area easily identifiable.  No wasteful repetitive coatings or risk of untreated areas
