RG-CHW® is formulated to be applied to chilled water systems with operating piping temperatures between 40ºF - 90ºF (4ºC - 32ºC).
RG-CHW® is a surface conversion compound utilizing mineralization technology, or the "Science of Minetics." RG-CHW® is gel compound which replaces the corrosion process by growing a mineral formation on and into the metal surface 50-200 angstroms thick. As time passes, the mineral layer on the substrate increases in thickness. RG-CHW® is not “new” technology; it is new to the chilled water industry and is a breakthrough for controlling corrosion under insulation (CUI). RG-CHW® is a non-drying gel compound that is easily applied to pipes, fittings, valves, tanks and vessels. RG-CHW’s non-skinning and non-sag properties make it a permanent solution for CUI on chilled water systems.
RG-CHW® prevents corrosion and stops existing corrosion from advancing. It requires minimal surface preparation on corroded surfaces (SSPC-SP-2, Hand Tool Cleaning), which drastically reduces the overall cost of a system remediation without pipe replacement. (Integrity testing is recommended on corroded pipe).
Installation thicknesses of 25-30 MILS allows the unique formulation of the gel to heal a breach (mechanical damage) of the mineral barrier, and the RG-CHW® formula is so unique, that even if the vapor barrier is breached allowing some moisture into the system, the RG-CHW® will buffer the moisture that migrates through the gel to an elevated pH.
RG-CHW® is typically applied on the pipe using PVC chemical gloves and a patented AccuTrowel™ tool. The opacity and color of the product (light green) allows for easy site inspection of an installation. RG-Cleaner is also available from Polyguard; this cleaner is specifically formulated to clean tools, equipment, and hands without harmful chemicals.
RG-2400® Cleaner is also available from Polyguard; this cleaner is specifically formulated to clean tools, equipment, and hands without harmful chemicals.
AccuTrowel™ is a stainless steel trowel set designed for use on various sized pipes ranging from 2" to 12" to aid in ensuring you apply the accurate mil thickness for proper pipe coverage and helps reduce material waste.
