EPD: Injectable mortar securing of threaded rods and masonry, 1670 kg/m3, Hilti HIT-HY-270 (Hilti AG, Kaufering plant)
The declared product of HITHY 270 is a twocomponent system. The resin component (component A) comprises a resin based on methacrylate as well as mineral and cementlike fillers. The curing agent component (component B) comprises of peroxide hardener, water and mineral fillers. Mixing the two components A and B in the static mixer initiates the curing (hardening) reaction of both binder systems. During the curing phase, a very strong bond is formed between the organic and inorganic binder matrix. The hybrid system formed during cement and resin curing results in a crosslinked duromer with desired design properties (high bond strengths within short curing time) and particular longterm stability. Composite foils are used for the twocomponent foil pack of HITHY 270. This kind of packaging serves the following purposes: waste volume reduction, easy storage and transport, less packaging material. Through legislation and increased public awareness users have increasingly become discerned towards the use of styrene and other highly volatile components with their resulting unpleasant odour and low flash point (flammability). The reaction resins used in all Hilti hybrid adhesives contain no styrene, are practically odourless and have a considerably higher flash point, i.e. higher than 100 °C in comparison to 34 °C for styrenebased products. HITHY 270 is the ultimate performance injectable hybrid mortar with approvals for fastenings in all masonry materials.
