Doublecure® 184 is used for the application on non-yellowing UV Radiation Curing Systems. It is an alpha cleavage type photoinitiator, which combines the characteristics of high photospeed and exceptional storage life. Its non-yellowing and low-irritating properties, makes it an ideal choice for clear coatings on paper, flooring, metal, plastics and wood. Doublecure® 184, when irradiating with UV light, undergoes a homolytic and intramolecular type of breakage to generate a pair of free radicals to initiate the polymerization of UV curable systems.
It does not require hydrogen donor to initiate its radicals. However, its radicals are very sensitive to oxygen in the air. Doublecure® 184 is strongly recommended when non-yellowing properties are crucial. Results obtained from an outdoor exposure study show that it gives better long-term non-yellowing performance than other initiators. Furthermore, it exhibits lower sensitivity to air inhibition than Doublecure® 173 during curing.

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.
