Baybond® PU 405 is an anionic/non-ionic crosslinking polyether urethane polymer used as the film-forming component in glass fibre sizes. This product becomes milky white when dispersed in water. This product has a non-volatile content (0.9-1.1g / 1h / 125°C, convection oven) of 32-35, a flow time at 23°C, (4mmcup) of 11-18, and a pH value 20°C (supply form) of 6.0-8.0. Baybond® PU 405 was developed for the sizing of glass fibres used to reinforce thermoplastics, particularly polyamide. Glass fibre sizes based on Baybond® PU 405 are characterised by their outstanding film-forming properties and very good adhesion. They have very good colourfastness, even at high temperatures. The mechanical film properties of the product are developed fully by post-crosslinking at temperatures from 170°C for a duration of 20 minutes. Baybond® PU 405 is also highly resistant to shear forces and hydrolysis.

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.
