E-SPERSE® 700 is a yellow liquid for emulsion polymerization. The nonionic surfactants, E-Sperse® 700 and 703, vary in their ethoxylation level and thus their hydrophile-lipophile balance or HLB. Matching the HLB of the emulsifier to the monomers and to the polymer is critical for optimal emulsion properties.
The choice of the proper one for your emulsion polymer system can best be determined by experimentation. E-Sperse® 700 and 703 nonionic polymerization surfactants may also be used in conjunction with other commonly utilized nonionic or anionic surfactants to produce smaller particle size emulsions. The E-Sperse® series emulsifiers are much lower foaming than traditional alkylphenol ethoxylates so lower levels of defoamers are necessary in the polymerization process.
Ethox Chemicals offers a wide assortment of surfactants that use a broad variety of chemistries which include sulfation, phosphation, esterification, alkoxylation and custom synthesis. Their E-Sperse® line includes not only pigment dispersants but also defoamers, leveling agents, foam wetting agents, specialty additives and reactive surfactants. They are always willing to work with customers to create new surfactant products even if it is for a single customer.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
