MasterProtect H 1100 - Hydrophobic impregnant based on isobutyltriethoxysilane

 

 

How does MasterProtect H 1100 work?

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. 

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

 

What are the unique features of MasterProtect H 1100?

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.

 

What are the benefits of MasterProtect H 1100?

  • 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
