GP-927 Plunger Lubricant is a modified petroleum-based lubricant, which is designed to provide superior protection for shot sleeves and plunger tips used in cold chamber die casting of aluminum and magnesium.  GP-927 shows a higher viscosity at elevated temperatures, than conventional oil-based plunger lubricants, which leads to improved lubrication and less smoke.
