SYNTECH HAG is the ideal material to fill and seal cracks, crevices, cracks and cavities, putting an end to infiltrations, quickly and decisively. It is a hydrophilic, hydro-expansive, low-viscosity polyurethane resin, accompanied by a specific accelerating activator (comp. B) to be dosed normally at 10% on the weight of the resin (comp. A).
IT IS EASY INJECTION
By means of specific manual pumps (from 40 to 200 Bar) or electric (200 Bar and more), using the special flat-head screw injectors.
IT IS CERTAINLY PENETRATING
Thanks to its low viscosity, its hydrophilic and hydro reactive components and its high capillary activity. It penetrates and permeates cracks up to amplitudes of 0.2 mm
IT IS EFFECTIVELY REACTIVE
Since, in contact with water or humidity, it increases from 10 to 20 times its initial volume, through a reaction and vulcanization process with the formation of a dense and elastic foam, with a cellular structure, which stops the infiltration and hermetically seals the injected fissure.
IT IS COMPATIBLE WITH ALL SUPPORTS
Concrete, natural stones, bricks, steel, laminates, cable coatings and polyurethane-based injection materials, possibly pre-existing.
IT IS CHARACTERIZED BY A SHORT TIME OF WATER REACTION
About 30″ (*) which can be accelerated, where necessary, up to 15″, increasing the dosage of component B.
(*) = The reaction speed (foam formation) is influenced by the temperature of the mixed material, by the conditions hydrodynamics, by the temperature of the structure and by the temperature of the contact water.
