1 Dow Oxygenated Solvents Product Overview and Selection Guide

2 Dow Oxygenated Solvents offer a range of solvency, water solubilities and volatilities that present a wide variety of formulating opportunities for the producers of household and industrial/institutional cleaners. Looking Beyond Today You need oxygenated solvents. Your applications depend on them. So you need a supplier who can deliver not only what you need today, but what you ll need for your future growth. That supplier is Dow. We ve been providing solvents for customers for more than 100 years but we re not resting on our accomplishments. We re continuing to innovate to help customers like you develop differentiated products, stay ahead of changing environmental regulations, maintain low cost to serve and compete in a fast-changing business environment. Dow s solvents portfolio include a wide selection of alcohols, including, esters, ketones and ethylene- and propylene-based glycol ethers. Front cover: Dow Oxygenated Solvents are ideal solvents for the coating applications and can be used in a wide range of other applications such as photoresist formulations, photoresist stripping for precision etching, edge bead removal and cleaning. The utilization of a solvent system with the proper balance of solvency, volatility and surface tension properties can significantly improve the application and performance characteristics of coatings. pg 2

3 Alcohols Dow s alcohols range from three to twelve carbon atoms, from propanol to 2,6,8-trimethyl-4-nonanol. A single hydroxyl group characterizes them, and performance is largely controlled by the related hydrocarbon structure. The low-molecular weight, water-soluble products are solvents for the manufacture of protective coatings, dyes and inks. These alcohols are also used in producing plastics, flavorings, perfumes, cosmetics, pharmaceuticals, cleaners and polishes. The higher molecular weight alcohols are only slightly soluble in water and are used as latent solvents for solventbased coatings and as coupling agents in waterborne coatings. They help provide the proper balance of desired properties in a formulation, such as viscosity, flow and leveling, and cure rate. The higher molecular weight alcohols are also intermediates for plasticizers, surfactants, lubricants, ore collectors, pesticides and pharmaceuticals. Esters Our acetate esters have good solvency power for many natural and synthetic resins (e.g., nitrocellulose) and are commonly used in lacquer thinners, wood lacquers and a wide variety of coatings. Isopropyl and butyl acetate are well established as volatile solvents for the manufacture and application of many types of finishes. Less volatile esters are used as tail solvents for organic coatings and as coalescing aids for latex paints. All the acetate esters are miscible with many common organic solvents. They are used broadly in printing inks, aerosol sprays and personal care products, as solvents for fragrances, cosmetics and personal care, and as a processing solvent in the pharmaceutical industry. Dow s line of esters, including UCAR n-alkyl propionates anducar Ester EEP, offers substantial flexibility in formulating coatings. Their linear structures contribute to effective viscosity reduction and to improved solvent diffusion from coating films. They have strong solvency and proper volatility for high solids coatings and printing ink applications. Odor characteristics are significantly more favorable than with other solvents of similar volatility. Their high electrical resistivity properties provide advantages in formulating high solids coatings for electrostatic spray applications. Solvents: Selection Guide for Coatings Alcohols Esters Ketones Glycol Ethers Propionate esters provide excellent replacement options for oxo-hexyl acetate, methyl n-amyl ketone, and xylene. They are commonly used in automotive refinishes, OEM coatings, appliance coatings, cleaning fluids and printing inks, as solvents for cosmetics/ personal care products and fragrances, and as a polymerization solvent for high solids acrylics resins. UCAR Ester EEP and the propionate esters also find use as solvents for the electronics industry.

4 Oxo Acids Dow offers a broad range of Oxo Acids. Oxo Acids are used in a wide variety of applications such as stabilizers, plasticizers, coatings additives, lubricants, pharmaceuticals, pesticides, perfumes, food additives, preservatives and chemical intermediates. Oxo Acids and Ketones are used as processing solvents in the manufacture of pharmaceuticals.

5 Ketones Ketones are an important class of industrial chemicals that are widely used as solvents and as chemical intermediates. They are known for being strong, versatile organic solvents and therefore are essential components of many consumer and commercial products. Ketones are used safely and effectively in everyday products such as paints, adhesives, printing inks and cleaners. They are used extensively in the coatings industry as solvents for nitrocellulose and other cellulose esters and for vinyl chloride-vinyl acetate and other resins. They are used as active solvents or dilutents, often in combination with other solvents. Their low densities, combined with strong solvency, make them desirable solvents for meeting Volatile Organic Compound regulations. Ketones are also used extensively in the manufacture of commercial products such as pharmaceuticals, plastics, fibers and films.

6 Glycol Ethers Dow s glycol ethers portfolio is offered in two product families: E-series ethylene-based, and P-Series propylene-based glycol ethers. Glycol ethers are excellent solvents for many types of applications. The combination of an alcohol and an ether functional group in the same molecule provides unique solvency characteristics with both polar and non-polar properties. This surfactant-like structure gives glycol ethers the ability to couple unlike liquid phases and be miscible in a broad range of hydrophilic and hydrophobic solvents. From electronics to coatings and cleaners, glycol ethers offer a wide range of properties to meet the ever-changing needs of the marketplace. Glycol ethers are used in many applications because of their ability to lower surface tension in aqueous systems, as well as to penetrate and soften soils. In cleaning formulations, they are widely used to aid the removal of greasy soils, to aid in solubilizing other components in the cleaner formulation, and to improve the storage stability of the formulations.

7 solvency allows glycol ethers to be used to reduce viscosity while minimizing VOCs. DOWANOL LoV 485 was recently developed to offer the lowest VOC in the industry (<0.5 wt%) and meet regulations while helping to decrease impact to the environment. In waterborne coatings, glycol ethers are excellent coalescent agents, and their unique hydrophobe/lipophobe balance allows for a broad range of coalescent efficiencies for different resins. They are also used as dye carriers in the textile, leather and printing industries and as solvents for insecticides and herbicides. For reactive and more hydrophobic systems, glycol ether esters and methyl capped glycol di-ethers offer stability and high solvency. DOWANOL Glycol Ether products can prevent a component from separating in cosmetic formulations and help maintain its clarity, even when the product is exposed to extreme temperatures.
