ALPHATEC® 171

Download Bulletin AT171

ALPHATEC^® 171 is a three-component polymer grout system consisting of modified epoxy resin, chemical hardener, and a chemically modified aggregate.

ALPHATEC^® 171 has been specially formulated for heavy duty chock grouting under many different types of machinery with metal-made supporting frames. That is why it can be used, like its aggregate-free version (ALPHATEC^® 170), in a sandwich approach. ALPHATEC^® 171 has been approved for use in chocking main propulsion engines in marine applications, as well as for miscellaneous deck machinery and auxiliaries.

Features

Ease of use, three-part mix

Good flow properties

Very high compressive strength

Good mechanical properties at high temperatures

Packaging and Safety

ALPHATEC^®171 is available in three-component, two litre sets. Each set is composed of liquid, hardener and filler. Larger sets are available upon request but, since pot life is a function of mixed volume and ambient temperature, they should only be used for the largest pours, such as main propulsion engines of 10 MW or more where the total chock volume can easily be 300 or 400 litres.

All ALPHATEC products are intended for industrial use, and should be used only by experienced personnel with proper equipment & training. Always use proper protective clothing, including gloves, face masks or shields, and wash any exposed skin thoroughly after using the product.

Mixing and Handling

Always use the full amount of hardener, pour it into the filler portion and mix thoroughly for at least one minute. Immediately after, add the liquid portion and keep on stirring until the colour change (yellow to green) has become homogeneous. A non-aerating mixer (Jiffy mixer or equivalent) should always be used.
