Desmolac® 4340 X/IB is a non-reactive linear polyurethane based on IPDI, with approx. 40 % in xylene/isobutanol (51:9). It is used as a binder for physically drying primers and finishes for plastics. This product has a non-volatile content (1g/1h/125°C) of 40 ± 1%, a viscosity at 23°C of 7,500 ± 1,500 mPa·s, a hazen color value of ≤ 150, a density at 20°C of approx. 0,94g/ml, and a flash point of approx. 22°C.
Pigment preparations such as Bayderm® Colours B-TO and C-TO (Bayer) are recommended for colouring formulations. It is also possible to use standard pigments or pigment/extender combinations. The solvent resistance of films based on Desmolac® 4340 X/iB can be greatly improved by the addition of Desmodur® N 75 (10 to 20 %, calculated on the solid resin). This will result in post-crosslinking of the film with atmospheric moisture after 1 to 2 weeks. However, Desmodur® N 75 should not be added until just before application of the coating to prevent reaction with the isobutanol in the solvent mixture of the supply form.

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.
