Product Description

Introduction

CM-WB inhibitory propylene glycol antifreeze, using industrial grade propylene glycol (99.9%), softening water, using professional resist package, special pigment production and processing. It is widely used in the process cooling loop, automobile and air conditioning system to provide antifreeze and anti-corrosion protection. CM-WB inhibitory propylene glycol antifreeze has the minimum antifreeze temperature-60ºC, the minimum available flow temperature-50ºC, and the maximum available temperature is 120ºC. CM-WB inhibitory propylene glycol antifreeze contains industrial compound corrosion inhibitors, which can provide protection for metals (mainly iron, copper and aluminum metals).

 Notes for use

1, prohibited to use tap water, groundwater and other high hardness water dilution;
2. No entry into other unidentified chemicals;
3. In order to extend the working life, it is recommended to use airtight, or use nitrogen seal to isolate oxygen;
4, the normal use of pH> 7.5, when the pH is less than 7.5, please contact senbo chemical technicians;
5. Do not use it in the non-working temperature range;
