Both products are comprised of a USP-Certified (food-grade) base propylene glycol and a proprietary food-grade corrosion inhibitor package. Extended Life Coolant (ELC) Corrosion Inhibitor for Propylene Glycol based Heating & Cooling Systems. It modifies the metal surface by absorption, making it less susceptible to corrosion. As such, where human exposure may occur, propylene glycol based heat transfer fluids are preferred. This article will answer the following questions. adroll_pix_id = "KAZWVOIGNJFDRDYYNILF3O"; Corrosion inhibitors for ethylene glycol solutions, with particular reference to cadmium-plated and terne-plated steel. adroll_current_page = "other"; Corroban 50 is a synergised molybdate / organic corrosion inhibitor which is ideal for MTHW, ... Corroban 90 and 99 are food-grade inhibited propylene glycol antifreeze’s that can also be used as bacteriostats to safely control microbial growth in food production applications. Description: coolants are preferred over the traditional ethylene glycol coolants.Corrosion inhibitor formulations are well developed for ethylene glycol coolants, but there is concern that the inhibitor suite for propylene glycol systems may not be as mature. Proper human safety products such as splash goggles, lab coat, NIOSH approved gloves and boots should be worn while handling and applying chemicals. The inhibitors in CoolFlow NTP are formulated to give the best possible performance and fluid lifetime at Propylene Glycol levels between 25 and 60% v/v. Glycol antifreeze coolant with corrosion and scale inhibitors - low toxicity food and beverage grade. Multi-metal inhibitors generally reduce the occurrence of corrosion via several mechanisms. – Order Online. Should be stored in original containers away from heat, direct sunlight. An aqueous inhibitor concentrate is available to provide corrosion protection where freezing protection is not an issue. Potentiodynamic polarization tests were carried out to study the effect of each chemical. Ethylene Glycol or Propylene Glycol Based Antifreeze. Chiller Fluids, Anti Freeze & Heat Transfer Fluid. Journal of Applied Chemistry 1959 , 9 (11) , 589-594. A mixture of 5.0% sodium benzoate + 0.3% sodium nitrite in 25% ethylene glycol has been shown to be effective in preventing the corrosion of cast iron and other metals both at room temperature and in conditions of intermittent heating. It is not intended to be used as an additive to food or pharmaceuticals. Automotive anti-freeze contain inhibitors that tend to react and coat heat exchange surfaces, thereby reducing energy efficiency. 86A Topsia Road The goal should be to minimize the amount of glycol in the fluid mixture, while maintaining the needed freeze protection and corrosion inhibitor content. 50% INHIBITED PG is specially formulated with a unique multi-metal corrosion inhibitor blend to passivate system surfaces and prevent corrosion. In most cases you should mix glycol with water. Reducing the Propylene Glycol concentration below 25% reduces the inhibitor concentrations to a level that may not provide adequate corrosion, scale and biological protection for a system. We deliver to clients across Canada, with your order shipped in 3-4 business days. Your On-Line Source for propylene glycol, ethylene glycol, corrosion inhibitors and buffer solutions. Accepta 8700 is a food and beverage grade mono-propylene glycol based antifreeze coolant incorporates additional corrosion and scale inhibitors. Due to immense corrosion in system, the rust in the system metal makes the glycol turn red in colour, ergo increasing the glycol degradation rate. The corrosion inhibitor protects metal surfaces from corrosion without reducing the system’s heat transfer efficiency. The incorporated propylene glycol inhibitor serves to modify metallic surfaces by absorption. 1 gallon of ChemWorld SR1 will protect 140 gallons of 20% glycol solution from corrosion.
