MasterProtect H 1100
Hydrophobic impregnant based on isobutyltriethoxysilane.
Description
MasterProtect H 1100 is a low-viscosity, clear liquid based on a selected high-purity, undiluted isobutyltriethoxysilane. This
class of silanes has a very low molecular size, which ensures effective impregnation of concrete and masonry surfaces through deep (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.
The treated substrates are therefore highly hydrophobic and will inhibit ingress of water and waterborne aggressive agents such as chlorides, while retaining the original appearance. The substantial reduction in water absorption of the treated substrates also assists in the thermal insulation characteristics.
Recommended Uses
MasterProject 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
Features and Benefits
- Effective water repellence – durability. Inhibits ingress of waterborne aggressive agents such as chlorides.
- Minimises surface efflorescence – Clean appearance of masonry surfaces.
- Breathable – Allows excess water vapour to evaporate from the substrate.
- Highly penetrative – Ensures long-term effectiveness even on surfaces exposed to traffic (e.g., car parks).
- Can be supplied with fugitive dye – The treated area is easily identifiable. No wasteful repetitive coatings or risk of untreated areas.
