2、 desired under this standard is a highly refined oil, compounded with suitable additives to improve its water emulsifying and rust-inhibiting characteristics as well as film strength and wetting properties. 2. APPLICATION: This material was originally released for application in lubricating systems
3、to eliminate the effects of free moisture in com- pressed air by absorbing the moisture and forming a stable oil-in-water emulsion. Additionally, the material is intended to promote longevity of cup leathers, packings O-rings and seals. 3. REQUIREMENTS: 3.1 GRAVITY: At 60F (15.6C) (A.P.I.): 24 min (
