The Afton Chemical Grease Portfolio
Multi-functional Componentry
Multi-functional componentry is a building block approach that combines several performance attributes into a single product. This is an efficient and increasingly popular way to streamline your grease portfolio. The right system can save time and money while maintaining flexibility in creating a full grease product line – from core to enhanced performance.
Building Blocks
Building blocks offer a flexible approach to constructing your finished grease formulation. Starting with an appropriate foundation – from core to enhanced –additional performance can be “dialed in” to meet the goals of your custom grease needs.

High Performance Additives
High performance additives are traditionally used by grease formulators to add individual performance characteristics to their finished greases, maintaining maximum flexibility and uniqueness of formulations.
Anti-wear (AW) and Extreme Pressure (EP) Additives
AW characteristics and protection against EP regimes are important performance characteristics that need to be incorporated in greases for various applications. Afton offers many different options for the formulator seeking to strike the right balance between structural stability, surface activity, performance and cost.
Corrosion Inhibition (CI)
Corrosion inhibition is critical in many grease applications. From testing in salt spray to Emcor dynamic bearings to yellow metal protection, Afton has a wide range of options to allow maximum synergy while minimizing the impact on thickener structure and other important performance criteria.
High Temperature
Grease manufacturers need special additives to meet the unique demands of applications for which heat is a critical variable. Afton offers a range of chemistry designed to meet the stringent needs of your individual grease formulations. From increasing oxidation resistance to improving structural stability at high temperatures, these components can help you meet the distinctive challenges of grease formulating.

| Zinc DialkylDithioPhosphate
(ZDDP)
ZDDP is an effective and cost efficient way for a grease formulator to reduce wear and oxidation in a wide range of grease formulations.
HiTEC® 7197G (C4/C5/C8)
HiTEC® 55450 (C3/C4/C8)
HiTEC® 7169 (C3/C6)
Excellent AW protection combined with antioxidancy.
Wider functional temperature range for protection by degradation of ZDDP.
Provides AW and oxidation protection at lower temperatures.
SECONDARY ALCOHOLS PRIMARY ALCOHOLS
Zinc complexity - all zincs aren’t created equal
• ZDDP requires partial decomposition to deposit Zn, P and S on the metal surface.
• The type, branching and chain length of the alcohol used can affect performance in several ways.
ZDDPs made from secondary alcohols decompose more easily than those made from primary alcohols providing anti-wear protection at lower temperatures.
Antioxidant (and EP) performance requires that sulfur be “released”; this process is made more difficult in ZDDPs made with longer alcohols.
• Branching of the alcohol groups will also affect the stability of the ZDDP in both positive and negative ways further complicating formulation challenges.

Corrosion Inhibition (CI)
| Rust Inhibitors
Protection against rust attack on ferrous parts is critical in many grease applications. From static to salt spray to dynamic bearings, Afton has a full slate of corrosion inhibitors designed to cost-effectively enhance your grease’s performance in these critical areas while maintaining grease stability, extreme pressure and wear protection.
• Succinate ester
HiTEC® 559
• Acidic inhibitor, used at low treat, good synergy with other CIs.
HiTEC® 538
• Poly ester succinimide
• Neutral inhibitor, good rust protection and friction reduction, synergistic
HiTEC® 614
• Low TBN calcium sulfonate
• Excellent in protecting against corrosive/ humid conditions such as ASTM B117 salt fog test
Formulating with rust inhibitors
Why don’t all additives behave the same?
Synergy
To meet the demands of severely corrosive conditions (such as 3% NaCl), individual rust inhibitors can offer some protection at higher treat rates. However, synergistic combinations can often be identified that can lower overall treat rate and cost.
Thickener Interaction
The complexities inherent in grease formulating include variations in grease thickener chemistry and manufacturing conditions which can have an enormous impact on additive effectiveness – especially with regard to interactions with polar additives such as rust inhibitors.

| Yellow Metal Protection
Well-formulated grease products should not be chemically aggressive to parts containing yellow metals.
