Bayhydur® 401-70 is a hydrophilically modified aliphatic polyisocyanate based on isophorone diisocyanate (IPDI), which is used as the co-reactant for aqueous resins and as the hardener for chemically resistant and weather-stable coating systems. This product has a NCO content of 9.4 ± 0.5, a non-volatile content (0.2g / 60min / 120°C) of 70 ± 2, and a viscosity at 23°C,(D=81,8s-1) of 600 ± 200.
Bayhydur® 401-70 is mainly used as the co-reactant for aqueous polyol binders from the Bayhydrol® range. Due to its hydrophilic character, Bayhydur® 401-70 can be easily emulsified in the aqueous phase. The properties (e.g. resistance to chemicals and solvents) of aqueous two-component polyurethane coatings can be improved by the addition of Bayhydur® 401-70.

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.
