Sormat ITH-Wi is a fast-curing two-component chemically unsaturated injection compound with good performance. ITH-Wi is developed from a special highly reactive substance which makes it possible to use in extremely low temperatures of down to -20 °C. The compound has lower viscosity (thinner fluid) than standard components in order to be possible to inject and blend with low temperatures. ITH-Wi is most suitable for concrete. Suitable with small edge distances e.g. attachment of facade cladding, recess bars, pin bolts for steel columns and ground bolts. Thanks to extremely little shrinkage, the ITH-Wi is specially suited for injection in connection with recess with reinforcement bars.

Leave the mixing pipe on partially used cartridges, which can be used within up to one month depending on the storage conditions. Replace the mixing pipe before re-use. Mixing pipes are included with each cartridge. The 300 ml cartridge can be used with standard silicone gun. Larger cartridges for professional use and more extensive works.

Installation in solid materials: Drill a hole according to the assembly data in the table. Diamond-drilling holes must be buffed. Clean the hole carefully from drill dust with a brush and blow pump. We do not recommend cleaning the hole with water because this would double the curing time. Fill up the hole to 2/3 with injection compound. Turn down the anchor rod manually and rotate it a few times in order to make sure that the compound has been distributed around the anchor rod. Note the curing times before applying load on the anchor. Install the detail to be secured by tightening the nut to the recommended tightening torque as shown in the table.

I) Open time period, before a chemical reaction (curing) starts. Curing time: before load can be applied on the anchor in a dry environment.
