I needed coolant/antifreeze for my laser cleaning machine. My shop is heated, however, I was concerned that freezing could be an issue in the event of a power outage. I needed coolant and antifreeze for my laser cleaning machine. Although my shop is heated, I was concerned that freezing could become an issue in the event of a power outage. I spoke with the laser manufacturer, and they confirmed that this product would be suitable for my application. However, it is a bit expensive, which is why I rated it four stars.

Works great for my laser engraver, reasonable price

Great stuff for cooling your CO2 laser! More balance cooling and heat Transfer. A absolute must if you’re in an outside shop. OMTech is the only place I found that sells it. Although buying direct through them it takes a long time and packaging isn’t that great, took a couple of weeks and the packaging didn’t make it, shipper sent it back, OmTech direct was gonna take weeks to verify the damage and resend so I got a refund. Buying through Amazon is faster (days), better packaging, and a much better customer experience.

used in a cooler for an induction forge.. Bought for the non conductive, low freezing point, and it's ethylene glycol.. Works so far expensive at $40 a gal

Works great in my laser chiller
