OAT-908 combines organic-acid inhibitors with sodium nitrite, sodium molybdate, sodium benzoate and triethanolamine. It is blended in Taylor, Texas, and is not dyed.\u003c\/p\u003e\n\u003ch4\u003eWhat is the freeze point of 20% ethylene glycol?\u003c\/h4\u003e\n\u003cp\u003eThe freeze point is approx. 18 °F (-8 °C) at 20% ethylene glycol by weight. The percentage is by weight, not by volume, so compare it against weight-percent freeze tables. It suits indoor closed loops that do not see freezing temperatures.\u003c\/p\u003e\n\u003ch4\u003eShould I choose EG 20\/80, 30\/70 or a stronger blend?\u003c\/h4\u003e\n\u003cp\u003e20\/80 is the lightest ethylene glycol blend in the line, for indoor loops such as CDU technology cooling loops, rear-door heat exchangers and chilled-water loops inside a conditioned building. If piping, dry coolers or equipment can get near 18 °F, choose 30\/70 or 40\/60, which carry more glycol and freeze at lower temperatures.\u003c\/p\u003e\n\u003ch4\u003eIs the OAT-908 package nitrite-free?\u003c\/h4\u003e\n\u003cp\u003eNo. OAT-908 is a nitrite-containing hybrid inhibitor. If your specification requires a nitrite-free coolant, this product does not meet it.\u003c\/p\u003e\n\u003ch4\u003eIs it hazardous?\u003c\/h4\u003e\n\u003cp\u003eIt carries the GHS signal word Warning: may cause damage to organs (kidneys) through prolonged or repeated exposure (H373). Ethylene glycol is toxic to people, pets and wildlife if swallowed, so clean up spills immediately. See the Safety Data Sheet for full hazard, first-aid and disposal guidance.\u003c\/p\u003e\n\u003ch4\u003eIs it DOT regulated for shipping?\u003c\/h4\u003e\n\u003cp\u003eNo. It is not regulated for transport by DOT in any package we sell, from 1 quart through the 330-gallon IBC tote, and ships without a hazmat surcharge.\u003c\/p\u003e\n\u003ch4\u003eEthylene glycol or propylene glycol?\u003c\/h4\u003e\n\u003cp\u003eBoth are offered at 20% with an OAT inhibitor. Choose propylene glycol (PG 20\/80) where accidental ingestion, pets or food areas are a concern; ethylene glycol is more toxic if swallowed. Neither is for food contact or potable water.\u003c\/p\u003e\n\u003ch4\u003eWhich metals is it compatible with?\u003c\/h4\u003e\n\u003cp\u003eOAT-908 protects steel, cast iron, copper, brass and solder. Avoid galvanized (zinc) surfaces and strong acids. Install it as a fresh fill after draining and flushing; do not mix it with phosphate-, silicate- or nitrite-free coolants.\u003c\/p\u003e\n\u003ch4\u003eHow do I top off or dilute it?\u003c\/h4\u003e\n\u003cp\u003eIt is supplied ready to use, so do not dilute it further. Top off with the same 20\/80 premix to keep glycol and inhibitor on spec; adding water alone lowers both. For any make-up water use deionized or distilled water only, never tap water.\u003c\/p\u003e\n\u003ch4\u003eAre the SDS, TDS and COA available?\u003c\/h4\u003e\n\u003cp\u003eYes.
