Outline
• Overview- Phosphate Esters- Colonial’s Phosphate Ester Product Line
• Selected Phosphate Esters for Industrial Lubricants
• Summary
CONFIDENTIAL USE ONLY 2
Phosphate Esters: Chemistry
• Anionic surfactants• Made from hydroxyl group–bearing
substrates and phosphating agents• Stable over a broad pH range• Show good solubility• General Composition
- Di-phosphate esters (d-PE)- Mono-phosphate esters (m-PE)- Free phosphoric acid - Unreacted alcohols or alkoxylates
Substrates- Alkanols- Alkoxylates- Fatty alkanolamides- Carbohydrates- Others
Phosphating Agents- Five (5) available- P2O5 and PPA dominate- Directly impacts the product composition
CONFIDENTIAL USE ONLY 3
Phosphate Esters: Properties & Performance
What Affects Properties of Phosphate Esters- Type of substrates- Phosphating agents- Degree of ethoxylation of alcohols- Phosphating process- Mono/diester ratios- Type of salts
CONFIDENTIAL USE ONLY 4
What Can Phosphate Easters Do?- Extreme pressure (EP) wear protection- Corrosion Inhibition- Boundary lubrication- Emulsification- Surface Wetting- Dispersing- Detergency- Giving antistatic effects, esp. on synthetic fibers- Fire retarding
Phosphate Esters: End Applications
• Metalworking fluids
• Hydraulic fluids
• Paints and coatings
• Plasticizers
• Cleaners
• Fire retardants
• Agrochemical formulations
• Ink

Phosphate Esters: Global Market
• The global phosphate ester market was valued at $ 843.9 M in 2017
• Expected to be at $1.2B by 2022 at a CAGR of 6.9% from 2017 to 2022.
• The growth driver is from - The Asia-Pacific region - Technological advancements in lubricants, surfactants, pesticides, fire retardants, hydraulic fluids,
plasticizers, and paints and coatings for application-based end-use industries
• Mainly manufactured in the Asia Pacific region- NA and EU have stringent regulations regarding manufacturing as well as usage of phosphate
ester.
