PLTL-45 – Total Solids Type II MIL-L-23398
Aerosol solid film lubricants are sprayed onto surfaces, allowing solvents to evaporate leaving the desired solid film lubricant. To obtain the intended film attributes, the aerosol needs have the proper ratio of solids to solvent. This test determines the percent solids in aerosol solid film lubricants using the procedure in Mil-L-23398.
A sheet of white lined paper is weighed, sprayed with an aerosol solid film lubricant, allowed to dry and weighed again. The percent solids in the aerosol is calculated and reported.
