METALGUARD A70
Universal Antifreeze Additive Package for use with Virgin and Non-Virgin (propylene and ethylene) GlycolProduct Description and Applications
METALGUARD A70 is more than just a universal additive package which meets both automotive and heavy-duty specifications. It utilizes proprietary technology to provide superior performance quite economically and possesses several advantages associated with organic extended life additive packages, including lower dissolved solids levels and the absence of sometimes objectionable inhibitor components. Aside from being a non-silicate, non-phosphate, non-nitrate, non-amine one-part inhibitor package, METALGUARD A70 minimizes cold weather additive package crystallization problems since it does not begin to crystallize until the temperature falls below 32ºF. In addition, it contains additives to minimize hot surface scaling while also preventing heat transfer surface fouling due to minor oil leakage.METALGUARD A70 additive package produces antifreeze that meets ASTM D3306, the specification for light-duty and automotive service and ASTM D4985, the specification for diesel and other heavy-duty applications. METALGUARD A70 can be used effectively with either ethylene or propylene glycol. This universal additive system can also be used with either virgin or high-quality reclaimed glycol from distillation units, reverse osmosis membranes, and most flocculation/filtration systems. WEBA Corp recommends that you send a sample of any non-virgin glycols that you are considering for use with any of WEBA Corp's additive packages; we will determine if any pretreatment will be necessary prior to blending antifreeze to ensure compliance with all required specifications.

Nearly all of OEM automotive light-duty ad heavy-duty specifications are patterned after or identical to the ASTM standard specifications given above. For individual OEM specification compliance contact your sales representative. Note that the ASTM specifications listed include the key performance tests (ASTM D1384, D4340, D1881, D2570, D2809).
Blending Instructions
Storage and Blending: Always store concentrated METALGUARD A70 additive package at a temperature of 60ºF or higher. To make antifreeze concentrate (97.8% glycol, 2.2% additives), first charge the desired quantity of glycol to the blending tank. The glycol should first be charged to the blending vessel at a temperature of 50ºF or higher, and at a pH of 7.0-9.5. Maintain this temperature throughout the blending procedure. Based on the quantity of glycol being treated, add 2.2% by volume of METALGUARD A70 while agitating or circulating glycol (two 55 gallon drums per 5,000 gallons of glycol). Continue to agitate for 30 minutes after all of the additive package has been transferred into the blending vessel.Water Quality And Dilution: When antifreeze concentrate is diluted to 50% by volume with water, the water of dilution must be of acceptable quality. Deionized water is the best to use, but other sources of water are acceptable as long as they contain no more than 350 ppm total hardness measured as calcium and magnesium compounds. Higher hardness levels may cause excessive inhibitor consumption, scale deposits and metal pitting.
Making Claims for Antifreeze/Coolant Blended with WEBA Corp's Additive Packages
The specifications listed in this bulletin are based on antifreeze produced with WEBA Corp's additive packages, virgin glycol and deionized water. Antifreeze blenders must demonstrate compliance with ASTM or other specifications with their antifreeze/coolant, because the quality of the glycol and water used is as important as the additive package. Note that OEM's have placed limits on the percentage of recycled glycol that can be used in factory fills as have other purchasers of antifreeze. Glycol quality specifications have also been established. Obtain copies of the specifications that you wish to meet, thoroughly read them and conduct any required tests, prior to stating that the antifreeze produced meets the specifications. WEBA Corp can provide assistance locating the necessary specifications/standards. To confirm that your finished products meet the required industry specifications, WEBA Corp recommends that you test your glycol and finished products at an accredited laboratory. Glycol should be tested for conformance with ASTM E1177 and finished products should be tested for the ASTM performance tests listed on this product bulletin. WEBA Corp can assist your company in preparing your samples for testing with pre-tests performed at the accredited laboratory. WEBA Corp will warrant our additive packages only if the recommended blending procedures are properly followed. In addition, the glycol or other base fluid used with our additive systems must meet industry or ASTM standards unless specifically exempted in our literature.
