4 FORMULATION GUIDE (Cont d) Flash Rust Inhibitor Addition of flash rust inhibitor is recommended to prevent flash rusting or early rusting. The following flash rust inhibitors are suggested: AMB (10% H 20) lbs./100 gals. Note: The use of Sodium Nitrite solutions has been found to occasionally cause stability and water sensitivity problems when used with. Use of this additive should be evaluated thoroughly in your formulation to insure compatibility. Dispersant The following dispersants are recommended for : Tamol 165 Tamol 681 D % based on pigments weight 1-1.5% based on pigment weight 1-1.5% based on pigment weight Thickener For increasing the viscosity of, it is suggested that the following thickeners be added incrementally under good agitation and allowed to mix for sufficient amount of time: Rheolate 300 RM 8W 5-10 lbs./100 gals lbs./100 gals.
