Both SCA and Extender are used to supplement engine coolants to provide a fully formulated heavy duty (HD) coolant. However, SCA’s and Extenders are as different as conventional silicate HD coolant is to Extended Life HD coolants. SCA chemistry is typically based on a combination of nitrite and inorganic corrosion inhibitors, while Extenders are typically based on nitrite and organic corrosion inhibitors. The use of SCA’s in Extended Life coolants or Extenders in silicate formulations will negate the benefits of the additive and could jeopardize the cooling systems life.
