METALGUARD® SCA80

Product Descriptions & Applications

METALGUARD SCA80 helps extend antifreeze-coolant life by providing an additional dose of inhibitors to protect all metals in the engine’s cooling systems. It includes additional stabilization for silicates, adds dispersing and suspend ing agents to help prevent scaling and fouling, and boosts additives that will control cylinder liner pit ting, and pump cavitation, erosion and corrosion.

METALGUARD SCA80 increases the nitrite levels in your cool ant by virtue of its high nitrite content. METALGUARD SCA80 can be used to con vert an ti freeze that meets the basic ASTM heavy-duty standard (ASTM D4985) to anti freeze meeting ASTM D6210, the fully-formulated, heavy-duty precharged antifreeze standard. Heavy-duty diesel engine cooling systems must effi ciently provide: effi cient heat re mov al, corrosion protection, scaling control and fouling control over long change-out intervals, and under conditions of heavy load factors.

Blending and Use Instructions

INITIAL PRECHARGE: When precharging new antifreeze con cen trate which con tains less than 2400 ppm Nitrite (as NO2) as confi rmed by a reliable test strip or by analysis, add METALGUARD SCA80 per the following guidelines to provide a min i mum of 2400 ppm Nitrite:

NEW ANTIFREEZE           ADD THIS VOLUME             ADD THIS VOLUME SCA80

NITRITE (NO2) ppm                   % SCA80                     -OR-               PER 5,000

MAINTENANCE CHARGE: METALGUARD SCA80 may be added to an engine cooling system on a fixed schedule at intervals of 20,000 miles, 250 hours of operation or 3 months to maintain proper inhibitor levels. However, for heavy-duty diesel applications with METALGUARD SCA80 it is best to use nitrites as an indicator of inhibitor levels. Check the nitrite level with an appropriate test strip or by analysis. If the nitrite level is below the min i mum accept able level (usually 800-1000ppm NO2) as indicated by a test strip, add one (1.0) ounce of ME T AL GUARD SCA80 per 1 gallon of cooling system capacity (assumed to be 50% coolant & 50% water). Retest and repeat as necessary
